How are automobile makers, and specifically their warranties, responding to biodiesel usage?
It’s kind of interesting to watch, truthfully. As the biodiesel industry gets older and wiser, more and more OEMs (Original engine Manufactures) are warming up to this idea and making positive statement about 100% biodiesel and this is reflected in their warranties. The truth is, it’s kind of tough for them to argue the fact. The diesel engine, after all, was designed for this. Caterpillar, John Deere, and New Holland all accept and explicitly warrant B100 biodiesel in their engines. Others are taking a more “wait and see” attitude. They are warranting blends like B20, or B5 but stop short of wholeheartedly endorsing the idea. Other say they “neither oppose nor endorse” the use of biofuels.
