Jimmy Joe, I am use Linux and I can get to the site....

I had that intent when I bought my first MB, too. But now I can see that all the work involved in modifying the car and filtering, dewatering, and hoping for WVO that isn't contaminated or pH'ed wrong is really hard and may permanently damage my incredible cars.

Also, I think Jimmy Joe has a good point about the energy you have to expend to make fuel. reduces the net gain, IMHO

Unlike FI, I am not too concerned about the legality, I passed my inspection with my EGR (acidentally) unplugged, and I paid my sales tax and I pay my yearly road tax (based on the vehicle weight, to account for road damage), but that said, I would prefer to buy bioD from a retailer or co-op.

I live in San Antonio where there isn't a single consistent bioD retailer, so I have considered making my own bioD. Still, it's alot of work. I would rather just buy it from a reputable retailer.

Good luck, keep us posted
