Does using bio-fuels void the warranty in your car?

    Depends. If you have a diesel engine and you run biodiesel through it, it should not void the warranty by any means. Biodiesel is a perfectly legitimate fuel–it’s even sold at the pumps in some states, like Vermont. However, if you want a car that runs off veggie oil, you do have to do some serious hack-work, (think second tank for the oil and conversion to a two-stage engine) which is highly, highly likely to void the warranty.
