If the hefty price tag of new diesel generators steers you away from making a purchase, you can still get the same benefits withused diesel generators. This equipment allows you to handle larger commercial applications, such as providing power at construction sites or manufacturing plants, without overextending your budget.

Used diesel generators are quite dependable: most run at 1,800 RPM and are water-cooled. Unlike air-cooled portable gasoline generators with a shorter lifespan, you can often get 15,000 to 30,000 hours of use out of a diesel generator before it requires significant work. And if a reputable seller has maintained the machinery well, it could last for several years.

You can often save 25% to 50% or more by buying used diesel generators. In addition, you can realize additional cost savings with your fuel purchases. On average, diesel fuel can cost 30% to 50% less than other fuels such as gasoline or propone. But you’ll need to schedule delivery of diesel fuel and have a large holding tank on premises.

Remanufactured vs. as-is warranties
The type of warranty you get usually helps you decide which type of used diesel generator to purchase: remanufactured or “as is.”

While you get the lowest price with an as-is model, you don’t receive any type of warranty and could simply be purchasing someone else’s problems. With remanufactured generators, dealers put a lot of work into them to make sure they look and perform as good as new. They also back up the quality of their work with a basic 90-day warranty. Remanufactured diesel generators will cost more, but you get more reliable equipment which means fewer problems in the future.
