Can You Run A Diesel Generator On 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?

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.

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 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 off-road diesel in my oil furnace?

Off-road diesels are coloured red to indicate that they are untaxed and can be used for off-road purposes. Construction fuel, machinery never used on public roads, agricultural service, and heating oil boiler fuel are all examples of these usage. Can these types of diesel fuel, on the other hand, be used to heat your home?

Yes, colored and off-road diesel is an appropriate alternative to heating oil in most cases. These days, most dyed and off-road diesels are ultra-low-sulfur diesel.

According to the EPA and most state rules, heating oil can be low sulfur or high sulfur. This means that, whereas heating oil cannot always be dyed diesel (for example, when used for off-road machinery or agricultural purposes), dyed or off-road diesel can be used as a heating oil substitute.

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 sources become short.

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.

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.

Which is better diesel or propane generator?

And for those worried about the environment, a propane generator is unquestionably the best option. Propane is one of the most environmentally friendly fuels available. Per gallon, it creates less particles and emits fewer greenhouse gases than gasoline or diesel. Propane exhaust is nearly odorless and colorless. Due to their poisonous emissions, diesel engines are forbidden from operating at specific hours of the day in areas where air quality is an issue. Propane generators may be used almost anywhere, at any time, with no environmental impact.

Another factor that benefits propane in the propane vs. diesel generator debate is the long-term cost of ownership. The total cost of ownership outperforms diesel or gasoline engines for portable or whole house standby generators due to lower maintenance, less fuel price volatility, propane’s molecular integrity, and propane engines’ remarkable shelf life.
