FAQs About Diesel Generators

What is the difference between No. 1 and No. 2 diesel fuel?

• No. 1 diesel fuel is typically considered the premium diesel fuel choice with extra lubricants and fuel additives that help clean the system. This fuel is also known to perform better in cold temperatures. No. 2 diesel fuel is more commonly available, doesn’t burn as quickly and is typically less expensive than No. 1 diesel fuel.

Can I use red diesel in a generator?

• Yes. Red diesel, also known as off-road diesel, can be used for engines that power off-road vehicles and construction equipment like bulldozers. However, using it for street-operated vehicles is illegal.

How long can a diesel generator run continuously?

• Diesel generators are often equipped with a 24-hour fuel tank, and some even come with a 48- to 72-hour tank. Read the owner’s manual or speak with a United Rentals representative to determine what capacity tank you need from your generator rental. Make sure to closely follow all safety guidelines and keep generators positioned outside and away from open windows to prevent dangerous levels of carbon monoxide from entering any homes or businesses.
