RE:RE:RE:RE:RE:RE:RE:mining.com(Shadow10) I'm really surprised they haven't pushed the propane thing more I used to own a pick up on it. The price was so cheap, not anymore though unfortunately but it burns so clean with very low emissions. Yes you lose horse power by maybe 15% but seriously the vehicles made today are made with so much they would be a regular horse powered vehicle as in previous years. Also it's easy to convert back to gas as well or even switch tanks in a dual service system? Anyway ske long! Worked on the project for years in the early stages lots of resource with little infrastructure needed other then mill.
