Gas and Diesel Generators Compared

Diesel generators do what other generators do, they generate power when and where it is needed most. However, some have argued that diesel engines will last longer than gasoline engines by a large margin, use considerably less fuel, and require no maintenance other than regular oil and filter changes. This may or may not actually be the case. At least that's what I thought when I started my search for an adequate generator. I am convinced that diesel is the way to go. Here's some of what I found out.

Both gas and diesel generators will basically provide the electricity you need, but it is sometimes difficult to get a really good comparison as to which is better or worse. If we start by looking at how you intend to use the generator, that helps. If you are mainly after a generator that will give you a reliable backup then the performance you require won't be as critical as it would be if what you really need is one that is depended on for everyday use. In general, I discovered that gasoline generators are not as fuel efficient as diesel, but that the diesel generators usually operate at less revolutions per minute and thereby give you more torque at the lower speeds. This translates directly into in increase in the life span of the engine.

Another generalization that I discovered is that diesel generators are more economical when it comes to how much fuel is actually used. But it is not all bad for the gas option. One plus for gasoline generators is that if they are properly maintained, they can perform and last nearly as long, if not as long, as diesel generators. One caution to be aware of about the diesel option is that if they are not used often enough, they can actually break down quicker. Knowing what sort of performance you require is critical to helping you make the proper decision about which is best for you. Depending on the application you have, and how closely you adhere to the manufacturers instructions, the performance will vary accordingly.

What about safety? Like any combustible fuel, both gas and diesel have to be treated with the utmost respect. They need to be stored in proper containers and in proper locations. Gas is more combustible and will ignite more easily by static. Next time you fill up your car or truck at the gas station you will notice little signs on, or near, the pumps that tell you not to use your cell phones while fueling. They also direct the consumer to turn their vehicle's engine off while filling up. Don't want any nasty little explosions as a result in a spark or static hitting the gas fumes. As for other health concerns, both types are dangerous if breathed too much. In the balance, I'd say that diesel generators are more safe than their gas cousins.

Cost wise, the diesel generators tend to be a bit more pricey. They have more expensive repair costs because the parts cost more to replace. Diesel fuel also costs more than gas. However, diesel engines tend to last longer and don't have as much maintenance needed. I feel like, in the long run, diesel generators offer more value and safety for most needs. Again, consider your performance requirements and go from there.
