They make conversion kits for bio-fuels.
It’s like regular diesel, but it has fewer BTU’s than regular.
It gels at higher temperatures than regular. But it is completely compatible with regular.
Well Talked to my dealership service department today and they do not recommend it and say that it will hurt my engine. Unfortunately there is no other diesel in the area. So I am gain to have to trade in my Golf TDI with about 35K on it.
