I do not profess to be knowledgeable in this area, but I wonder if anyone here has used any alternative fuels to power their car or truck? Anyone using E85 with any luck, and if so what are the positives and negatives? Propane or CNG? Anyone running Biodiesel in a G body or your daily driver? Anyone here ever run a car on used fry grease? Benefits/drawbacks? I ask this because I drive a lot every year and am thinking about and researching other fuel sources to power my cars for economic reasons, but the thread is open to any and all discussions of alternative fuels and not just the ones mentioned in the title. (Moonshine anyone? :lol: ) This is meant to spark debate and as a way to share ideas so all input is welcome.
