We spend about $4500 per year on gas. Right now I don't have a diesel car but i'm looking hard at a 95 E300

I'd love to hear from people who are running exclusively on bio D or WVO.

How much time and money is going in to this?

I have the space and the means, but for my lifestyle it would need to replace all my fuel and, after the learning curve, not take any more time than i spend mowing my lawn (close to an acre)

If i could reduce that to $1-2 / gallon It would drive my car decisions- Like maybe a diesel suburban and his & hers Mercedes.

Thanks
