Will running B20 void my warranty?
Ford allows B5. If the fuel causes the problems then it will not be covered.My truck is a 2003 6.0L and I would be buying it from a local pump. I have seen people posting on here, stating that ford allows up to B20. I am just trying to confirm this and was wandering if there is any literature stating that?
Something is wrong there. I run about a B13 concentration (5 gals of B100 per tank of ULSD) and my truck runs great. Much Much quieter than it ran even with 2 stroke. I am about to go to a B20 tomorrow when I fill up.Carefull where u get ur bio diesel from. I got a tank full of 2% bio and 98% diesel and the van runs like beat her badly. No power and even the wimpy Hondas are killing me now. Can not wait until I get the good ole diesel back in her.
