who is running propane on their diesel?

Curious on price of kits, diesel fuel mileage and propane mileage before needing refill. Thanks.

Thanks 250turbo, that didn't sound too good. The more I find out the less enticing this is. If there was substantial mpg gains, it might be worth the risk but I am not looking to make extra power so this mod doesn't sound worth pursuing.

Diesel-Propane dual fuel systems can work well but the low-tech systems are very risky. Propane's critical compression ratio is ~12:1 and its use must reduced as engine loads increase or detonation will result (see Dual Fuel Fumigation). I expect that Swamps Diesel Performance has had experience with the low-tech systems. A diesel-propane system that uses a fuel map to control propane supply is much safer and the only two that I'm aware of that have a fuel map are the EcoDiesel System and the Diesel Magnum.
