If you are tired of paying sky-high diesel fuel prices, this is the solution you have been searching for. We installed a Golden Fuel Trekker vegetable oil system in this 2003 Chevy Duramax Diesel. This system is better for the environment, plus it allows you to run on vegetable oil in addition to diesel fuel. Since some restaurant owners have to pay to dispose of their used oil, they are normally happy to give it to someone that is willing to take it! The beauty of the Golden Fuel system is that there is no need for a cumbersome, home-filtration unit.
