I have been using my own fuel to run my cars and trucks and when I filled my rotary "Rotus" I realized how crazy buying fuel for cars has become. I guess I can get used to it but it hurts. I have not bought gas for several years. Man I feel for those who do! I run diesels and make biodiesel and run 2 on wvo -waste veggy from local restaurants.

Hey, at least it's cheaper now than it was six months ago. Regular is hovering just above 3 bucks a gallon here. I filled up a couple weeks ago for $2.90-something. What are you running on the wvo? Mercedes?

My wife drives a 2005 Jeep Liberty CRD on biodiesel (70% now in the colder weather) and I drive a 2002 VW TDI on grease along with my garbage scow

'94 Dodge Cummins (my grease collector).

Bad ass! Pros and cons? Please tell or post a link with the best advice on this subject. Thanks! and keep sticking it to them!

Trouble with bio is when I factor in the time to collect and refine it costs much more than diesel
