I was talking with my neighbor today about his forklift business and mentioned that I had seen a post on here about Mitsubishi 2.6 propane (Clark) forklifts. He called me a little while later and told me he had everything on the shelf to do the conversion if I wanted but said at this altitude, there would be about a 10% loss in power.My question is, would this conversion work well with the conquest turbo and is this conversion really cost effective? Do you get"miles per pound"?since propane is sold by the pound? What is good mileage with propane?How does it compare in mileage with gasoline?
