hello. i recently bought a 2001 ford F250, 7.3 ltr psd. great truck!

want to run bio diesel, but had a few questions...

1) will use of bio diesel void my ford warranty. i've heard this but not sure if true... anyone know re: this?

2) what type of biodeisel is recommended for my vehicle?

3) are there other things i should do in terms of modifications/additives i should do/use?

Nice truck!

As I recall, Ford says that anything under B5 is fine. But there are plenty of folks that are running MUCH higher than that.

Ide start out with B5, and go up from there. Be sure that it is ASTM certified fuel!

Good luck!
