How to Avoid Running Out of Oil

August 19, 2026August 18, 2026

With the heating oil season just over the horizon, it’s important to keep in mind how much oil you’ll use during the winter. But it’s also a good idea to start checking heating oil prices regularly! At the time of writing, oil prices have spiked due to the war with Iran! Heating Oil is at about $4.25- $4.50 per gallon! This is due to the price of crude oil, and it’s incredibly expensive to fill up a tank with oil! Especially with prices where they are now, it’s crucial to be on top of your usage and keep track of your oil level! So the question stands: “How do I avoid running out of oil? Well, don’t worry, I’ll be answering all the important questions below!

Filling up regularly will help prevent runout! The last thing you want is to wake up to a cold house!

Heating Oil Tank Capacity

The maximum capacity of a standard heating oil tank is around 275-330 gallons. But it’s a good thing to know that these tanks will rarely be filled to their true capacity. The reason for this is that dealers will fill up until the whistle stops. This’ll actually make the true capacity different. On a 275, it will be 250 gallons, while on a 330, it’ll be around 315 gallons. Your capacity will have some effect on how much and how frequently you order oil. Ideally, you’ll want to order oil when your tank gets to a quarter. On a 275-gallon tank, this is around the 75-gallon mark, while on a 330-gallon tank, it’s closer to 95 gallons.

You should NEVER let your tank’s oil level get below 1/8. The reason for this is that this is around the time your system might start to catch sludge. On Roth tanks, this isn’t a problem. However, on standard steel tanks, sludge can be sucked into the feedlines. When this happens, your lines will get clogged, which will cause the system to shut down, resulting in no heat! On a 275-gallon tank, the 1/8 mark is about 35 gallons. But if your tank’s feed lines are top-fed, then this will be the point at which you run out of accessible oil.

What Happens When You Run Out?

When you’re running out of oil, the first thing that’ll happen is that you’ll have no heat. No heat means waking up to a cold home, which isn’t a fun experience! However, it’s important to note that waking up to a cold home doesn’t always mean you’re out of oil. It could mean that there’s a faulty part in the boiler/furnace or the feed lines are clogged! It’s always good to check! One time, my boiler’s starter wasn’t working properly! We had heating oil, but the starter wasn’t working, so my family and I were freezing!

When you run out of oil, you’ll want to run and grab some diesel. This’ll hold you over until your delivery of oil arrives.

If you’ve run out of oil, the very first thing you should do is contact a local oil dealer to place an order! Try to see if they can put you in for an emergency delivery. Once you’ve placed the order, go to the gas station and get about 5-10 gallons of diesel. This should hold you over until your delivery arrives. If you need the step-by-step guide to this, you can check out what to do here.

How Long Will a Full-Tank Last?

If you know what size your tank is, then you’ve got a baseline. You’re going to have an easier time figuring out how much a full tank of oil will last you. However, a Smart Oil Gauge will make the process of finding this out much easier for you! In my articles on Spring and Winter usage, I calculate specifics on how much you’ll expect to burn if you’re interested!

However, if you haven’t guessed by now, winter sees the most heating oil usage by far! Primarily due to the cold weather outside, you’ll find yourself burning around 5-7 gallons a day! Sometimes even more if you have a large house and use it for both heat and hot water. You might see yourself ordering oil more frequently during this time! Typically, you’ll need to order oil every month or so, depending on how much you’re using.

But on the flip side, during the spring and summer months, you’ll end up using significantly less oil! During this time of year, oil usage is going to be at a low. So you might only see yourself burning less than a gallon a day. Running out of oil is very unlikely during this time. But even so, don’t let your guard down!

Your average daily usage is going to be different depending on the size of your home and what the temperature outside is.

Final Thoughts

Avoiding running out of oil is fairly easy. So long as you’re on top of your heating oil usage and tank level. Make sure that when your tank starts to get low, you order at a quarter tank. This gives you enough time to get the delivery before you run out! You can use a website like our FuelSnap website to get the best prices on heating oil in your area! With the combined use of the Smart Oil Gauge and FuelSnap, you’ll get a leg up on other homeowners!

Making sure that you’re on top of your level and usage is crucial to make sure you’ve got oil in your tank. Keeping an eye on this will prevent you from running out as long as you’re on top of it!

Happy Heating!

Preparing Yourself for Heating Oil Season

August 5, 2026July 22, 2026

If you’ve watched Game of Thrones, you’ll know the iconic phrase “Winter is Coming”. Well, it’s August now, which means Heating Oil Season and Winter are just around the corner! Just like in the show, it’s important to understand that in the Northeast, it’s bad not to be prepared for what’s to come. Winter is peak season for heating oil, and now that it’s August, there’s a lot for you to do before winter is in full swing! Like every winter, you shouldn’t go in unprepared!

Fall and Winter are just around the corner! Which means soon your home will look like this!

Changing Out Your Air Filters

Forced air is an increasingly popular form of heating. If you use this, then now is the best time for you to change out your air filters. Ideally, these should be changed out every couple of months! However, if you have pets, then these should be changed out more frequently! But during the summer months, especially, they’ll get much dirtier. This is often due to collecting allergens, pet hair, dust, and dander! Changing out these filters is crucial to maintaining a healthy home, especially if you live with people who have allergies!

However, what’s the process for changing them? If you follow the steps below, you’ll understand exactly what you have to do to replace them!

The first thing you should do is turn off the furnace. This is crucial because your furnace might turn on if you’re changing out the filters! You don’t want that to happen!
Then, you’ll want to remove the side door to the furnace to access the filters. After doing this, snap a quick picture of how they’re installed currently. This will help you make sure the new ones are installed correctly after you’ve taken the old filters out!
Find out what size your filters are. If you haven’t done this before or are unsure as to what size filters you have, you’ll want to get this information. The most common size for these filters is 25x20x1. But if you don’t have any replacements, you can stop by the hardware store and pick up some.
Once you have the replacement filters, you’ll need to replace them! The replacements should have arrows showing how they’re installed. Follow those so you can install them properly!
You’re all set! Just close up the furnace door and turn it back on!

Changing out your filters is pretty easy! Just make sure you turn off your furnace when you do it!

Gathering Firewood

If you’ve got a fireplace or wood-burning stove at home, then you might know that you have to gather firewood. My family and I have a wood-burning stove, so typically we start to gather firewood around May-June. The earlier you gather it, the better, because it gives the wood time to try out before you burn it! But if you start stocking up now, then you’re still on the right track! Sometimes the cold weather doesn’t start until late September, early October anyway!

If you don’t have a lot of time to gather firewood on your own, then buying pre-cut wood is an option! However, it tends to be a little bit more expensive. You’ll be able to find them at places such as Home Depot, Lowe’s, Tractor Supply, and even some gas stations! But if you’re like my family and have been doing this for a while, you’ll have a log splitter! This speeds up the process of cutting up wood! Rather than relying on an axe. These machines streamline the process!

But if you have the time, gathering and splitting your own wood will save you so much money! Some woods, however, will tend to burn better than others. Oak, for example, is the most popular for burning. It’s not messy, and it takes some time to burn. However, pine is very sappy and can take a bit longer to dry out. Birch, on the other hand, burns quickly, and it doesn’t last very long. However, this makes it an excellent fire starter!

Stocking up on firewood is a great way to prepare your furnace and wood burning stove for the long winter ahead! This’ll also lower your heating oil usage if you have both!

Heating Oil Tank Inspection

As the years go by, your heating oil tank will get older. This often makes it susceptible to general aging over time. The tank itself will experience wear and tear as it gets older. For this reason, regular tank inspections are important for your tank. While this process doesn’t take a long time, it’s crucial for your system’s functionality and your safety.

In this section, I’ll be covering a brief explanation of what’s involved in a tank inspection. But if you want a more in-depth explanation, check out this article here.

Inspect the Legs to make sure that they’re sturdy. Also, make sure that there’s leaks in the tank.
Make sure there’s no rust on the seams of the tank.
Check the bottom and sides of the tank for any signs of leaking oil.
Make sure that the oil lines have no leaks.
Check the oil filter to ensure it’s not leaking.
Check the top of the tank and fittings for any damage, rust, or cracks.

These are the key points you’ll need to look at when getting a tank inspection!

System Tune-Up

Annual system maintenance is important for your heating oil system to function as intended. Making sure your system is properly maintained is a requirement to ensure that the system itself doesn’t shut down when you need it. If it’s been a while since your last system service, or you need one, contact your local HVAC technician. They’ll be able to do all the required service and maintenance to make sure that your system is in tip-top shape! But keep in mind the price. Usually, system maintenance will cost around $300-$400 on average.

However, when you contact your HVAC company, see if they offer a maintenance contract. These service/maintenance contracts will help you stay on top of your system’s maintenance. This’ll ensure that your system is in good shape for when you need it. Some HVAC companies will actually give you a discount when you sign up with them! It’s a good thing to ask!

Fill-Up Your Heating Oil Tank

Now that it’s getting to the end of summer, it’s a good time to fill your oil tank. Making sure that you have a full tank of oil will be very helpful when winter comes. Filling up your tank of heating oil will make sure your tank is ready to go when the temperatures start dropping! If you’re getting low now or are sitting at around half a tank, now’s a good time as any to order oil. It’s always a good idea to go into heating oil season with a full tank!

Your tank gauge is another important tool for you when it comes to monitoring heating oil usage and level. Most tanks come with a float gauge. However, the Smart Oil Gauge is another useful tool to track your data. You’ll have access to everything that you need at the touch of your fingers! You’ll even be able to order oil with our FuelSnap integration. FuelSnap lets you get the best selection of dealers and prices in your area!

Getting a fill-up now of all times is a great idea! This’ll make sure that you’re all ready for heating oil season!

Closing Thoughts

There are plenty of things that you need to do before heating oil season arrives. If you have the above-mentioned available to you, you’ll be fully prepared for the winter! Make sure you’re prepared when going into heating oil season and winter! You won’t want to be blind sided by a snowstorm or cold weather and not be prepared. If you’ve got a wood-burning stove or fireplace, stock up on firewood. If you’ve got a heating oil system, make sure that you get your tank filled and your system serviced!

As temperatures get lower and lower, we’re going to slowly start turning on our systems. Winter is around the corner, which means we’ll need to be warm for the cold months to come! Do not be un-prepared for what’s to come!

Happy Heating!

How Long Does a Tank of Heating Oil Last

July 29, 2026July 21, 2026

It’s currently late July, which means that we’re in an awkward spot where you’re not burning heating oil. However, heating oil season is just over the horizon! During this time of year, you’ll likely only be using heating oil for hot water, if at all! But even though it’s currently summertime, it’s important to understand that heating oil season is getting closer and closer. So it’s time to start preparing! There are a lot of different factors in how long your heating oil tank will last you. Here’s what you need to know!

The Size of the Tank

It seems like a no-brainer, but the size of your tank will determine how long a full tank will last you! In the modern age, the most common tank sizes are the 275, 330, and Roth 1000L tanks. Now, something to note with these tanks is that while their maximum capacity is 275 and 330, their true capacity tends to be 250 & 300 gallons. The reason for this is that the oil companies will leave the top couple of inches of the tank open for airflow. This prevents the tank from leaking and overflowing when you receive a fill-up. It’s also important that your tank has a working vent alarm. This’ll help indicate when the driver will need to stop pumping.

An uncommon but effective way to store heating oil is with a dual tank system. Dual-tank systems utilize two tanks in tandem. One tank receives the fill, and oil pushes into the tank that’s vented. This pushes air out of the system that builds up when the tank is being filled. The benefit to these systems is that your capacity is twice the size and you don’t have to order oil as frequently. However, you’ll have to order in larger amounts. These tanks will also always be level with each other! The tanks will drain in tandem and then equalize with each other to ensure both tanks have the same amount of oil.

These are the different Roth tanks. They have an array of different sizes. Commonly, anywhere from 110-400 gallon tanks!

But if you have an underground tank, the capacity tends to be 500 gallons. Although they can get to sizes up to 2000 gallons in some cases! However, that’s very rare, especially nowadays! Underground tanks that are older than thirty years tend to be removed often. This is because underground tanks can now be environmental hazards!

How Your Home Effects Usage

Your home plays a major role in how long a full tank of heating oil is going to last you. I’ve compiled a list of all the major effects that your home has on your oil consumption.

Size of the House: Homes with an average square footage of 1500ft, you can see themselves burning around 500 gallons of oil annually. On larger homes, say 3500 square feet, they will easily burn around 1500 gallons every year!

Your Home’s Insulation: Homes that are well insulated will burn significantly less oil than those that aren’t. For example, a 2500 square foot home that has good insulation might only burn 600 gallons annually. However, if that same-sized home isn’t well insulated, you could see that home burning up to 1200 gallons of oil a year!

System Age: A home that has a system that is up-to-date and well-maintained will use less oil than a system that isn’t. Systems that are well taken care of and maintained can last upwards of thirty years! The newer the system, the less overall oil you’ll have to burn! This means the full oil tank you have will last you much longer! You might see your oil usage reduce by upwards of 30%!

Inside and Outside Temperatures: Both the temperature in the home and outside the home will determine how much oil you’re using. During the summer, you likely won’t burn much oil because it’s hot out. Meanwhile, during the winter, it’ll be much colder out. So you’ll tend to burn more oil during this time!

Daily Usage

Daily usage is an important part of your overall consumption! I mentioned this briefly in the previous section, but usage, at its core, is based on temperature. Both indoors and outdoors!

On a warm summer day, you’re likely not going to turn on your heat! So during this time of year, you’ll only use heat for hot water. That is, if you don’t have electric heat! During the summer, you’ll likely be burning less than a gallon a day. So during this time, your usage is at a minimum.

However, during the winter it’s different. This time of year is much colder than the summer, so you’ll often have your furnace turned on to burn oil to heat the home. If you don’t have a secondary form of heating, then you can see yourself burning anywhere from 5-7 gallons a day, at least!

Average daily usage for CT in the winter can change drastically. But this is a rough average.

When Do I need to order Oil?

A lot of homeowners ask themselves this question. Now, while everyone has a different system and consumption, I have an answer. At FuelSnap, we recommend ordering oil at around a quarter tank. On a 275-gallon tank, that’s about when there are only 75 gallons of oil in the tank. This is the perfect time to order oil! When you’re at a quarter, you’ll have enough oil to hold you over until your next delivery. But this will also allow you to order oil at a reasonable price for a fill-up! Most dealers will offer a lower price per gallon once you order a certain amount.

However, if you let your heating oil tank run out, then you’re going to want to order as soon as possible! Running out of oil can be dangerous for your system. When the tank runs out of oil, this can cause sludge to get caught in the feed lines. When sludge gets in the feed lines, it can clog your system and prevent oil from being drawn into the boiler or furnace! If you run out, you’ll have to have an HVAC technician prime your system.

Checking Your Tank Gauge

It’s important to check your heating oil tank gauge often! Checking your tank gauge will help you get a better idea of what your current tank level is. Checking it frequently also helps you monitor your usage and helps you estimate how much you’re using daily. But two different types of tank gauges are commonly seen today.

The float gauge is the most common. It comes with all heating oil tanks, and while some might look different from others, they function the same way. In short, they function based on a cork bobber on the end of a metal rod. That metal rod connects to a colorful disc in a plastic cylinder. The disc lines up with writing on the cylinder, with level displays. The disc will display 3/4, 1/2, 1/4, and more.

The Smart Oil Gauge is a wireless tank gauge that reads off an ultrasonic signal. This gauge sends its signal down to the oil level, where it then reports back to the app. You’ll then be able to see what it transmits on your phone! All you need is your smartphone and a WIFI connection! Once you have the Smart Oil Gauge set up and linked to the app, you’ll get usage data and level readings at the touch of your fingertips!

The Smart Oil Gauge is the perfect tool to be able to monitor oil level and use data! Simply connect it to your WIFI, get the app set up, and you’re good to go!

Conclusion

There are a lot of factors when it comes to how long your oil will last. This is combined with usage, level data, tank size, and house size. All of these contribute to how much oil you’re going to be burning daily. Your daily usage is the major contributor that determines how long a tank of oil will last you.

Ensuring your home has good insulation will determine how much oil your system is burning. If your home is well insulated, then you won’t have to worry about burning a lot of oil! Plus, the larger the tank, the larger the oil capacity is. The more tanks you have and the larger they are, will make or break how often you’ll need to order oil.

When is the Best Month to Buy Home Heating Oil?

November 5, 2020May 6, 2021

One of the benefits of home heating oil is that you can buy it on your own schedule. Some house have multiple tanks which last for several months between fills. In this post we explain the best month to buy home heating oil.

What Causes Heating Oil Prices to Fluctuate?

To determine when to buy home heating oil, it is important to understand why prices fluctuate. There are three primary drivers of heating oil prices to be aware of:

Crude oil supply and demand.
Local heating oil supply and demand.
How you buy your heating oil (i.e. whether you order heating oil online or rely on automatic delivery).

Crude Oil Supply and Demand

Crude oil prices have the most significant impact on heating oil prices. Since home heating oil is a derivative of crude oil, the global supply and demand for crude oil can move heating oil prices up or down. Crude oil is the base fuel that is used in gasoline, diesel, jet fuel, heating oil, and lubricants in all sorts of machinery.

When the global demand for crude oil declines – so does the price. This is because production of oil does not stop immediately, and producers still need to offload their supply. This scenario played out in early 2020 as the COVID-19 pandemic ground global travel to a stop. All of sudden, nobody was flying on airplanes or even commuting to work anymore. As a result, there was suddenly too much oil being produced, and prices dropped dramatically. In April, 2020 prices for heating oil futures contracts even dipped below zero! We broke this down in a pretty cool post here when this happened. At the time, folks were paying as little as $0.99 per gallon for heating oil on FuelSnap!

As COVID-19 ground global travel to a halt in April, 2020, crude oil futures prices went negative. There was suddenly more oil supply than demand and producers needed to offload their supply. This directly impacted heating oil prices at the time, which we broke down in this blog post here.

Local Heating Oil Supply and Demand

Local heating oil supply and demand also impacts heating oil prices. In densely populated areas on Long Island, there are hundreds of thousands of oil-heated homes, and many heating oil dealers to choose from. As a result, the dealers must be very efficient and offer competitive pricing and fast delivery. The end result: heating oil prices in Long Island tend to be lower than other parts of the Northeast.

In less densely populated areas, there may be only one or two heating oil dealers to choose from. They can charge significantly more for heating oil, and don’t even have to deliver right away. Where there is a reduced supply like this, heating oil prices tend to be much higher.

There is also the question of the best month to buy heating oil. You may expect to get a better price during the summer / off-season. However, heating oil dealers tend to make fewer deliveries during the off season. As a result, they are less inclined to lower prices and be very competitive. Below is the historical price for heating oil over the past 30 years. The takeaway: the effect of crude oil supply and demand on prices far outweighs any seasonal effects on heating oil prices.

heating oil historical prices — Heating oil prices fluctuate with the market price for crude oil. As can be seen over the past 30 years, heating oil prices tend not to fluctuate with the seasons. In other words, cold weather generally does not lead to increased heating oil prices. Source: MacroTrends.net.

Will-Call or Automatic Heating Oil Delivery

While the price for heating oil will move up or down with the market, the biggest factor that dictates the price you pay for heating oil is whether you buy as needed (will-call) or have automatic delivery. Automatic delivery is billed as a ‘premium’ service and comes with a premium price. This price premium is generally around 40 to 50 cents per gallon, but as high as $1.00 per gallon or more with some dealers! Imagine a winter where you use 1200 gallons of heating oil, and your neighbor paid $1200 less than you for the same oil. That’s the difference between automatic delivery and will-call. If you’re on automatic delivery, then the best month to buy home heating oil does not apply, since the oil will be delivered on the company’s terms.

You can take advantage of significant savings on heating oil by only buying heating oil as needed on a site like FuelSnap. FuelSnap dealers compete for your business by offering the best prices for heating oil possible. And if you’re worried about running out of oil, just install a Smart Oil Gauge to send you alerts when the tank is low.

Bottom Line: Order Heating Oil Any Month of the Year

So, when is the best month to order heating oil? Since heating oil prices depend on the market price for crude oil, it does not matter which month you order heating oil. The only exception to this is when it is really cold, as you may find it difficult to get heating oil in a timely manner.

Even during a cold snap, you can always check heating oil prices near me on a site like FuelSnap. You will see which dealers are available in your town, as well as when they can make the delivery. You will save hundreds of dollars on average compared to automatic delivery over the course of a season.

Just remember, do not let your tank get too low waiting for a good price. If you run out of oil in the middle of the winter, you make have frozen pipes and a much more expensive problem on your hand. At that point, the best month to buy home heating oil no longer matters. As we like to say, the best thing to do is reorder at a quarter (tank) – no matter what month of the year.

Happy heating,

Steve

How to Read a Heating Oil Tank Gauge

May 5, 2020May 6, 2021

In an oil-heated home, nothing is more important than making sure you don’t run out of heating oil. Even if you pay a premium for Automatic Heating Oil Delivery, it’s important to occasionally check your home heating oil tank to make sure you do not run out. In this post, we’ll walk through the nuances of reading a typical float-style heating oil tank gauge and introduce some alternative ways of monitoring your fuel oil tank.

How to Read a Float Gauge in a Heating Oil Tank

Most fuel oil tanks come with a traditional float-style gauge. This fuel oil tank gauge features an arm with a float attached to its end, and a hinge. There is a plastic vial with a disk that indicates how full the heating oil tank is. As the float lowers, so does this disk. For a detailed breakdown of how an oil tank works, check out our blog post how an oil tank works here.

How a home heating oil tank works. The tank includes fill line, vent line, vent alarm / whistle, and gauge. — A typical heating oil tank features a float gauge with a hinged arm. As the float lowers, the visible disk on the top of the heating oil tank moves down accordingly.

To read the level of a float gauge, look for the tick marks on the plastic vial. These typically indicate Full, 3/4, 1/2, and 1/4. Because the home heating oil tank is rounded at the bottom, these gauges are not very accurate when the tank is low. As a good rule of thumb, always order heating oil online at around 1/4 full. This gives you a few days for the oil to arrive before running out.

Note: Some ‘experts’ say you should look at where the top of the disk lines up with a tick mark, rather than the bottom. These float gauges are nowhere near precise enough to make such a distinction, so just look for where the middle of the disk lines up with a tick mark to determine the level.

Multiply the level shown by your fuel oil tank size to approximate how much heating oil is in the tank. For a 275 gallon tank, 1/4 full is approximately 0.25 * 275 = 69 gallons. For a 330, 1/4 full is approximately 0.25 * 330 = 82.5.

A heating oil float gauge features a disk inside that shows how full the tank is. This should only be used as an approximation of how full the tank is. — Most home heating oil tanks feature a float gauge like this one here. The yellow disk can be used to approximate how full the fuel oil tank is. Because of the rounded bottom of a fuel oil tank, the gauge will go from 1/4 to empty quicker than it will go from 1/2 to 1/4. As such, it is very important to reorder oil when the gauge is reading 1/4 full to prevent a runout.

How Accurate is a Heating Oil Float Gauge?

Since these are not precision heating oil tank gauges, they should only be used as an approximation of how full a tank is. Because of the moving parts inside, these can also be prone to wear over time. If you suspect your heating oil float gauge is stuck, simply unscrew the plastic vial by hand. Use your finger to press the disk down. If the gauge is not stuck, the disk should easily move down, then slowly float back up and remain up, indicating the arm is moving freely.

One of the ways a heating oil float gauge can get stuck is by simply rotating inside the fuel oil tank. This can happen over time, and the result is the float is wedged against the side of the tank, unable to move.

Another problem that can arise is the float itself becoming less buoyant over time. As seen below, the float can develop sludge that prevents it from floating on top of the oil.

Home heating oil float gauges can break down over time. In this particular gauge, the float was covered with sludge after many years of use. — Heating oil float gauges are susceptible to many issues over time, including sludge build-up as shown here.

How Much Heating Oil Should I Order and When?

Once you know how much oil is in your tank, you’ll need to figure out how much to order. Use the guide below to determine how much oil your tank can take.

Amount to Order = Tank Capacity – Current Level

For a 275 gallon vertical heating oil tank, the max capacity is 250 gallons. The reason it is not 275 gallons is because there is always an air space left at the top of the tank after a fill. This allows the oil to expand in the fuel oil tank and prevents the tank from being over-filled.

If your 275 gallon vertical heating oil tank is 1/4 full, we know that 275 * 0.25 = ~69 gallons.

Amount to Order = 250 – 69 = 181 gallons or fewer. An order of 150 gallons, in this case, should easily fit in the fuel oil tank.

A 275 gallon home heating oil tank holds 240-250 gallons depending on its orientation. Use this table as a guide to know how much oil to order.

*A 330 gallon home heating oil tank holds 288-305 gallons depending on its orientation. Use this table as a guide to know how much oil to order.*

By using the above guides, you should be able to determine when to order heating oil for your home. Find the best and cheapest heating oil dealers near you with FuelSnap to avoid being overcharged by local oil companies!

What if I Want to Order 200 Gallons?

Since many dealers offer a discounted price for 200 gallons, you may be tempted to wait until your tank is lower that 1/4 full to order. This can be risky with a float gauge, as they are notoriously inaccurate when the fuel oil tank is that low. Instead, we recommend two options if you would like to get your tank that low:

A Smart Oil Gauge. This will report your oil level to within a couple of gallons. The Smart Oil Gauge knows the specific geometry of your heating oil tank as well. As such, it can account for the rounded edges and the reduced amount of oil in the bottom of the tank.
A yard stick. Using a yard stick to measure the specific number of inches of oil in the tank will give you a good idea of how much oil is in the tank. This is obviously cumbersome, but much more reliable than the float gauge. Once you’ve measured the level, in inches, check it against a tank chart to determine the level.

Smart Oil Gauge - WiFi Heating oil gauge - will show exactly how much oil is in a tank, and give a countdown to a quarter tank. — Using a Smart Oil Gauge is the best way to determine how much heating oil is in your fuel oil tank. The Smart Oil Gauge works extremely well when the tank is low, and will give a countdown of days until the level will be at 1/4 or 1/8. Using the app’s ‘shop for oil’ feature, you will also see the maximum amount of heating oil you will be able to order at any given time.

How Much Heating Oil Will I Use in a Day?

This is a great question to be asking yourself as you plan your next heating oil order. The first factor is whether you are using oil for heat only, or heat and hot water. If you are using heating oil for hot water, you will continue to consume oil year-round. Your usage may be reduced to 1-2 gallons per day in the summer months, and as high as 6 or more gallons per day in the winter months. This depends on the size of your house, how well-insulated it is, and other factors. The age of your heating system and keeping it well maintained are also contributing factors.

The only good way to know how much oil is used on any particular day is by installing a device like the Smart Oil Gauge. The Smart Oil Gauge uses an ultrasonic sensor to measure the oil level every hour. It then graphs this data over time, giving you usage statistics.

Smart Oil Gauge is a heating oil tank gauge that will show you how many gallons per day you are going through. — The Smart Oil Gauge allows you to tell exactly how many gallons of home heating oil your home uses over an hour, day, week, month, or year. These statistics are extremely helpful when adjusting the thermostat throughout the year.

Use the Float Gauge to Approximate Your Heating Oil Tank Level

Now that you understand how to read a float gauge, don’t forget that it is only an approximation. For a precise tank level when the tank is low, consider a Smart Oil Gauge or using a yard stick. Both of these options will give you a much better indication of the tank level.
