Is Diesel, Natural Gas or Gasoline Best?

There are several different fuel choices for commercial generators. Fuel availability in your area, shelf life, and other factors will help in your decision for which type of commercial generator is best for your business.

Propane/Natural Gas

Pros: For standby generators, they can be hooked directly into your gas utility lines (no fuel storage necessary), they are clean burning, and quiet running.

Cons: Lower output (may need larger generator compared to diesel)

Diesel

Pros: The diesel generator is the most fuel-efficient. A gallon of diesel fuel will last 2 to 3 times longer than gasoline. Diesel generators are designed to run continuously for hours, are very durable and dependable.For this reason they are the most common choice for commercial generators.

Cons: Diesel generators are noisier, require delivery and storage of diesel fuel, and they are usually the most expensive, which makes them common for larger, commercial/industrial applications.

Gasoline.

Gasoline generators are smaller, and not commonly used in commercial situations. They are more common for recreational (camping) and short residential uses.
