New To This Forum...? On BioDiesel For My 2003 6.0
 

Will my 2003 F350 Diesel 6.0L run on BioDiesel? Or will it cause problems?

Appreciate any help.

running good quality made BD should not cause you any trouble. My father-in-law run B100 in a 06 6.0L and has had no problems..about your warranty Ford will allow up to B5 anything over that and the risk is yours to take, however ford must show that the failure was directly caused by the Biodiesel in order to void you out. if the rearend breaks it should be covered, if an injector goes then get out your wallet

Welcome to FTE :-X25 And welcome to our biodiesel forum! Bio will run just fine in your truck. Stick around here long enough and we'll have you making it yourself!:-jammin

BTW if the BD in your tank, when you take it in for service, is B5 or less they are gonna have a very difficult time proving you have been running anything different.

Not that I would encourage you to be dishonest but stealerships are anything but honest and ya gotta fight fire with fire.
