Of course why bother with that since it won't save you a dime in fuel savings. Probably take a thousand years to break even
.
Why not buy an acre of land and grow rapeseed? 102 gallons per acre should give you more than enough to drive annually farther than the average American reasonably should. What i like about the Centurion, is that it makes biodiesel production so feasible, it'd be cheaper to grow your own fuel than buy it from foreign nations.
Bio will give you slightly less power, so a turbo would do, and it'd probably get better efficiency as well!
