Petrol in Alberta, Canada is $0.61/l cdn ($0.40/l USD), propane is $0.40/l ($0.26/l USD).

I have converted several EFI vehicles to propane. With the Vanagon, and Jetta, Honda etc., water temperature is the same as gasoline. With the Vanagon, I had a pyrometer probe in the exhaust for 10,000 kms and noticed no difference in EGT between gasoline or LPG. I hear it said that propane engines run hotter, but that has not been my experience.

I do notice a loss of power with the low compression ratio vanagon. Just barely noticable, so its not a lot ..... but it is less. Other cars I have converted to propane, like the VW GTI 10:1 engine, there was no difference in power after you advanced the timing a lot. There are timing advance kits which allow a dual advance curve for different fuels. Unfortunately I'm not aware of anything available for the vanagon. If I could get a steeper timing advance curve for propane, and 10:1 compression, power output should be identical to gasoline. That is the case with other applications anyway.
