Anyone running Propane, or thinking about it?

It is all that has been said, clean, efficient, cheaper?, oil stays clean, plugs stay clean and you lose quite a bit of power. It isn't cheap to maintain the vehicles and you need a BIG tank. When I was a police officer the city that I worked for ran a pilot program and converted about half the fleet to propane. The biggest problem was that propane does not give anywhere near to the gas mileage of gasoline and it isn't readily availiable. We were constantly running out of fuel during the shifts and at that time you had to get a tow truck back to the garage , can't put propane in a five gallon fuel can and that wouldn't get you far anyway. I can't see any savings since it takes more propane to travel equal distances and it isn't that much cheaper. JMHO
