ok here goes my dad was looking into running biodiesel. ford dealer said he
can only run 5% bio diesel per tank or it will kill the injectors . is 5% bio diesel
going to make more power or better miles in his truck or mine? they said 5% for all powerstroke diesels i have a 95 f250 7.3 powerstroke he has a 05 f250 6.0 powerstroke.is 5% even worth putting in the tank ??

 

Moved to proper forum.

 

No change in power or milage. 5% will improve the lubricity of the fuel.
Yes 5% is worth it.

If it was my truck I would have no problem running 100% BD. you have the same chance of getting bad Diesel as bad Biodiesel. If bad fuel causes issues with your engine it is not covered by the warranty.

“….we have tested biodiesel at Stanadyne and results indicate that the inclusion of 2% biodiesel into any conventional diesel fuel will be sufficient to address the lubricity concerns that we have with these existing diesel fuels. From our standpoint, inclusion of biodiesel is desirable for two reasons. First it would eliminate the inherent variability associated with the use of other additives and whether sufficient additive was used to make the fuel fully lubricious. Second, we consider biodiesel a fuel or fuel component—not an additive…Thus if more biodiesel is added than required to increase lubricity, there will not be the adverse consequences that might be seen if other lubricity additives are dosed at too high a rate.”
