Can A Diesel Generator Run On Home Heating Oil?

If you have home heating oil, you can run a diesel generator and use the heating oil as a fuel source. However, losing power for any length of time during the cold months could put a strain on your fuel supply. We recommend using a propane generator wherever possible. They run quieter and require less maintenance because they have a dedicated fuel source. Standard can supply you with both a propane tank and a generator.

Is home heating oil the same as diesel fuel?

In almost all furnaces, diesel, as supplied at many gas stations, is a suitable replacement for home heating oil. Both diesel and heating oil No. 2 are petroleum distillates that provide nearly the same amount of heat and can be used in the same systems.

Can I use heating oil for generator?

Although they are quite similar, #2 home heating oil and #2 diesel oil are not the same. It merely has the same lubrication and ignition properties. Home oil is not intended for use in internal combustion engines, according to refiners. Fuel designed for use in furnaces may not contain the same ignition accelerators, smoke suppressants, or biocides to kill bacteria and fungi as are found in diesel fuel used in automobiles.

If you use home heating oil in a generator, you risk voiding the manufacturer’s warranty, which could result in catastrophic damage. Damaged fuel injectors, fuel pumps, and engine glazers are among the first problems you’ll encounter. If heating oil was safe to use in compression engines, fuel firms would advertise it, but they don’t, and for good reason.

A generator requires additives that are not present in residential heating oil. It’s a sure-fire way to shorten the life of fuel injectors, the injector pump, and other components if you use it. The warranty will be void because the failure is not due to a manufacturing flaw, as previously stated.

Keep in mind that diesel oil is thicker and so has higher lubricating characteristics. It gels more easily in cold temperatures, making starting more difficult, and it can also create rough running in engines that aren’t prepared for it.

Can you mix diesel fuel with home heating oil?

Yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes Diesel is near enough to home heating oil to be used as a replacement, and it burns safely. In fact, our experts advises keeping a moderate amount of diesel on hand in case of an emergency, as you never know what can happen, such as terrible weather or an unforeseen supply shortfall.

However, keep in mind that if you decide to keep diesel at home, it must be stored in the proper container (yellow denotes diesel, red denotes motor gasoline, and blue denotes kerosene, just so you know!). You should never keep diesel fuel for more than six months at a time since the quality diminishes and it becomes dangerous. Even if you use fuel additives to extend the life of the fuel, storing it for a year is the maximum amount of time that is prudent.

However, this should only be a short-term remedy! While diesel is totally safe and functional as a temporary heating oil substitute, it isn’t meant to be stored in your tank for long periods of time. Diesel fuel is an excellent alternative in a pinch, but it is ineffective and not recommended for long-term heating.

Can you have a whole house generator if you have oil?

The general rule for replacing the oil in your whole-house generator is to do so once a year or every 200 hours of use. This number of hours corresponds to around 8 1/2 days of electricity, and while we hope you won’t need your generator for that long, it’s something to keep in mind. Consult the product manual for your generator to find out exactly what kind of oil to use. In terms of oil, a whole-house generator normally requires two quarts.

Other Items

  • Spark plugs – after a year of operation, your generator’s spark plugs might become dusty, worn out, and covered in dust and debris. Changing the spark plugs improves the performance of your generator.
  • Air filter – Just like a car’s air filter, your generator’s air filter can become clogged with dust and grime. This is why it’s critical to replace your air filter as part of your regular maintenance.

Why is home heating oil more expensive than diesel?

The price of crude oil is the key factor of both home heating oil and diesel fuel prices. Refining costs (13 percent), distribution and marketing costs (12 percent), and taxes are the remaining components (12 percent ). The cost of crude oil accounts for 61% of the retail price of diesel fuel.

What kind of oil is used for heating homes?

The most prevalent heating oil is kerosene. It’s also known as the 28-second, because it’s a lot lighter and cleaner than the 30-second. As a result, it is a popular choice among many homeowners.

What is the difference between fuel oil and diesel oil?

One of the most significant differences between diesel, fuel oil, and bunker fuel is their combustion efficiency. The combustion efficiency of hydrocarbons is also a feature of the hydrocarbons. The hydrocarbon sizes within each, not the hydrocarbon classes, are the most significant distinction between diesel and fuel oil.

Can I use diesel in my generator?

The major purpose is addressed in the initial use. Will you use your portable generator as a tool for handyman or construction work, or as a backup generator in case your house loses power? Will it serve as your primary power source or as a backup for a remote camping spot or cottage in the woods?

The cost of fuel will be determined by the generator’s required size. Will a few gallons suffice, or will you need to transport tens of gallons to suit your requirements?

For commercial/construction work, you will most likely have any fuel you require, and because gasoline is a common fuel, a size-appropriate generator can be simply selected. Any of the three fuels—gasoline, propane, or diesel—is a simple decision.

This might apply to your cabin, as well as hunting and camping expeditions. Getting a few gallons of gasoline on hand for when you need it makes great sense and is definitely the most likely option.

If your generator is simply used as a backup, you’ll want to think about how much storage you’ll need and how long the gasoline will last. Before recycling your inventory, you should determine whether adding fuel stabilizer is necessary to extend its life.

Propane generators are portable, but they require a bit more effort because you’ll need to bring extra filled tanks or have access to a larger tank. The way you use it is determined by how fast and readily you expect to be able to purchase propane fuel or replace tanks.

Another suitable fuel alternative is diesel, which has a high availability and is more stable in storage than gasoline. However, depending on where it will be utilized, most generators are noisier and may pose a greater environmental risk. Worksite safety is unlikely to be an issue, but the backyard and keeping the neighbors pleased may be.


The Winco HPS12000HE Tri-Fuel Generator is one of a few that can run on gasoline, natural gas, or liquid propane.

You can also acquire one of Impco’s Tri-fuel conversion kits to convert an existing gas-powered generator to run on the three fuels.

What you need know is that each fuel’s BTU or energy at burn will be different, and the engine’s power generation or HP will decrease, giving you less power when using propane or natural gas.

The tri-fuel option, on the other hand, gives you an advantage in long-term generator use when fuel supplies become scarce.

Non-portable backup generators in the entire house market are more likely to be connected to your natural gas supply or liquid propane sources such as 300 or 1000 gallon LP tanks. These are common fuel sources in both residential and commercial construction. The NG/LP fuel available is expected to last for several days, if not weeks.

When compared to gas and diesel engines, these sources produce less BTUs and have lower power output. As a result, diesel engines must be larger than gasoline engines to produce the same level of power.

Sure, huge gasoline and diesel tanks may be obtained to support this effort, but long-term fuel stability remains an issue, and diesel engines are frequently used in larger applications due to their more stable fuel characteristics and power output. If the unit isn’t well isolated, noise levels can become a problem.
