Propane generators use a lot of fuel. A diesel generator will use about 1/2 gallon per hour on about 1/2 load. My last run of 58 hours with my 5500 watt generator used 19 gallons of diesel.
On Onan's site they list 1/2 load amounts,
5500 LP .8 gallons per hour
5500 Gas .6 Gallons per hour
5500 Diesel .4 Gallons per hour
Owners with LP have looked at replacing the generator with a gas or diesel generator. Then found that it would cost $5,000 to $10,000 too replace it.
Hi Ron,
I will question the replacement cost of the LP to gas. would it not be as simple as changing the fuel line and the jets in the Carb. I was under the assumption that an LP was a gas engine modified to run Propane. I think the big problem would be to add a gas tank as most LP gen. are used on older diesels.
