    I used to drive propane fueled ambulances that had converted gas engines. They were really cold blooded and under powered till at operating temp. You have to watch your miles on each tank and idle time. Our mechanics had a grill tank and a hose set up to limp vehicles back to fuel.The fuel gage is useless! Filling it takes a while. The warmer it is out, the longer it takes. I have stood in the hot 90 degree sun for 40 minutes a few times. The tanks and lines are pretty pricey too. Propane is cheaper, but how long to make your money back? The state shuts down in a big event you can't get fuel.

    How does propane perform in the higher compression ratio of a diesel?

    propane trucks

    I have three propane powered trucks, GMC 6500. You can buy these trucks for nothing at the auction. Mine start fine and run great even below zero. My fuel cost is right at $1.00 per gallon including the road tax. I have my own bulk propane tanks and pump at the shop, and it takes about 10-15 minutes to fill each truck with about 100 gallons. when I first went to propane the savings in the first tank of propne just about paid for the bulk setup at the shop. If you sign up with some suppliers they will furnish the bulk tank but your cost per gallion is more.

    fuel mileage

    I don't know what kind of fuel mileage two of three trucks get. Those two are only used for plowing and salting. The third one is a service truck and is used to pull a 30 foot goose neck trailer. It averages about 7 miles per gallon.
    I can drive the service truck around for less then what I can drive my diesel pickup.
    One dollar per gallon for propane verses four dollars for diesel.
    On the propane the governemt gives you a tax credit of 50 cents per gallon, then you have to pay I thing its 13 cents per gallon road tax.
