How much oil should a generator burn?
I have a Cummins/Onan 20KW Propane generator. Just purchased new. With hurricane Sandy, the generator ran for 5 days. After 2.5 days, I stopped it and had to add 1/8 quart oil. After the second 2.5 days, the power came back and I had to add another 1/8 quart. At first I was startled at the oil consumption. I called the dealer I bought it from and he said its totally normal. I then called cummins and they also said its completely within spec. Was I too optimistic in thinking it should not be burning any oil? Thanks
