I am participating in an energy audit through the NRCS that is supposed to show me how to cut energy costs here at the "poor farm'. I am all for anything that will save energy which equates to me as money. Their was one thing the auditor said that I did not agree with, but I really did not pursue the issue with him, but instead I thought I would get input from this vast well of knowledge. He stated that I should think about getting away from diesel power and going to propane. I went through this once in the late seventies. We put a 65 Ford p.u. with a 352 CI motor on propane, a 190 Allis, a Ford Granada and two C cabover Ford trucks on propane. Our findings were that they saved a little money considering LP was so Much cheaper than gasoline at the time. We also figured that it had taken about twice as much LP as compared with gasoline. Unless things have changed with the fuel consumption of LP I cannot see for the life of me what you could save using it.
