Howdy- It seems more often than not (and not all that surprisingly), biodiesel users are also Mac users. For those of you who aren't aware, Biodiesel refers to any agro-based fuel used in a Diesel system. It can be a 95%/5% mix of diesel to soybean oil (B5), pure soybean oil (B100/SVO), or even pure waste vegetable oil from restaurants (WVO). As crazy as it seems, any current Diesel car can run on the used french-fry grease with almost no modification. Anyway, I wanted to know if any users here are active biodiesel users! I'm about to convert my 04 Jetta TDI (essentially just adding an extra fuel tank and filter to grab all the french fry chunks), and wanted to know how your experiences have been. Share!!
