ford will only warrenty 5%. but remember they also won't warrenty your repairs even if it was caused by bad Diesel because they can't contol what people put in thier tanks. others including my self have run blends from b20 to pure b100 in 6.0s w/o issues. i would change your fuel filters after the first tank or so because bio will really clean out you fuel system and all that crud will plug you filter. Our trucks injectors are very sensitive to fuel pressure and when your filters plug the pressure will drop and can eventually starve the injectors of fuel which can be bad. my truck, and all other diesels i have, love bio and seem to run a lot smoother. check out the Alternative Diesel Fuel Forum below this one for lots of reading. with diesel prices these days i think more and more people are going to be switching over to bio/bio blends.

I have added 1/2 gallon per fill up for about 10 fill-ups. No real sign of any change. Don't really expect to notice anything good or bad ........ just a long term decision for the lubrication on the fuel system. I also add Stanadyne. Again - just a personal choice.
