But will Ford ever lift the >B5 ban?
 

I think Ford's position on BD is nothing stronger than B5. Does anyone know if Ford is even considering increasing this?

Might sound crazy, but I'd spend an extra $1 (or more depending on the concentration) per gallon to buy biodiesel but I'd want it stronger than B5 and I don't want to run into warranty issues.

If dino-diesel prices keep rocketing up, the cost factor may become moot, but I'd like to keep my warranty alive on my '05, at least for another 4 years and 11 months.

Any Ford insiders willing to comment?
