I have an 05 6.0 L. When I got my truck I found a paper where Ford Motor stated they only recommend B-5 as a useable biofuel, with the diesel for various reasons. Does anyone know if they changed their stance. I went to a Pilot station yesterday and they only had B-10. I went elsewhere. Any info would be great. Thanks
i have the same engine/truck and have run all blends and try to run b100 as much as possible. If I had my choice i would only run b100, weather permiting, but sometimes my bio distributor isn't available or is out of fuel for a day so I have to put a couple gallons of D2 in the truck. Your truck will run perfect on biodiesel, just beaware your fuel filters my get clogged fast and if they get really clogged your injectors will starve for fuel which is very bad.
The only real possible problem you may have, is carbon deposits building up at or near the piston rings, since biodiesel has a higher ignition resistance compared to the dino variety. This is generally considered to be a problem with direct injection (as apposed to indirect) since the bio fuel is more likely to reach the piston unburned without a prechamber for premixing.
Now this is only a general rule and is based on older direct injected diesels that had lower pressure injectors that didn't atomize the fuel as well as the newer injection systems, such as the ones used in powerstrokes.
I wish they sold B100 or B-anything where I live, the older injection systems don't hold up very well on strait LSD or ULSD (I have to run additive).
