I'm 15 and wanted to get a diesel as my first car. Was thinkin about the previous generation ram cummins, but I can't afford diesel (around 4.20 a gallon+ near me). So do any of you guys have any experience with waste veggie oil? Free gas would be pretty cool. Any comments, like/dislikes, or anywhere I can go read about it would be appreciated. And where are some good places I could buy one from? Thanks.
