Hello all! A friend and I have been disscussing diesel emissions and alternative fuels. First with emissions. How much pollution does your normal light duty diesel p/u put out compared to a similarly equipped gas truck? Also, on alternative fuels.... There was a guy at last years Summit Racing Truckfest that had a Unimog that ran on used cooking oil. What does one need to do to a diesel equiped vehicle to run this type of fuel? Anyone have any good websites or articles they can share? I am not trying to put down diesels or start arguments. My friend almost bought a TDI Jetta and for my next truck I would liek a diesel equippe Dodge. While we were talking about these vehicles, we were wondering about these topics... Thanks!
