Is Onan Worth The Price?

When you find an Onan diesel generator for sale, most people recommend you grab it. It is a quality name brand generator that is able to handle anything you need to run off of it, even though some people feel that the watt numbers are a little low.

It runs off of diesel fuel, which in most cases means that you have very little maintenance on it. Some people use diesel powered engines for years before ever truly beginning to experience a problem. The good news with this Cummins Onan diesel generator is that if you do end up experiencing problems with your generator, parts and service is easy to find. However, you will most likely have to go through an authorized dealer to get help. In most cases, this is not a problem because they are available everywhere.

One major downside is that the spark arrestor is sold separately. It is easy to find, but it is a required accessory that some people feel should have been included. It will raise the price of your generator cost by a little bit by buying it.

Overall though, this 3.2 diesel generator is a very high quality generator that is worth the investment. It has a good name backing it, a company that has been in the business for many years, and it has proven through past generators that Cummins knows how to create quality. However, this one, by far, is much better than previous Cummins Oran generators.
