biodiesel

[08pwrstrokr6.4]

i think i may not know how to operate a search engine.ive looked in the bio section and here and in the 6.4 performance area only to retrieve minimal information.so what i am wondering is there any issues with pure bio in a tuned 6.4?is anyone doing this?i can see why it would be bad in a untuned dpf on truck.i know that cylinder wash with dino diesel is bad and that bio is bad enough by itself without an engine throwing more in for regeneration.so if any of you guys are running bio in your trucks i would like to know about it.any issues you have had to include filter changes,oil changes and the likes,small to large anything.also please be so kind as to list what grade bio you are running and if you stepped up tank by tank (ie b5 to b20 to b50 to b100).thanx for all the help guys.

I'm pretty sure they can't handle over like 5 or 20% b/c of the injectors.

I personally avoid bio like the black plague

I run b20 in all of our engines, we have never has a fuel related problem and have been using if for 5 or 6 yrs and burning prob 75K gallons a yr in everything from a 6.4 and new deere engines to older cats and cummins. In my opinion most of the bad rap it has gotten is bs made up by the oil companies so you wont use it, when it first came out there were no national standards and there was some bad stuff being put out there, but for the last few yrs ther are standards jsut like dino fuel. All of the bio we use is made from soy oil, I dont know anything about all the other kinds out there.

I'd be a little concerned about running straight bio in a 6.4 because of viscosity. The injection pressures on these trucks is WAY up there. Blend up to 20% on a DPF-deleted truck I wouldn't fear, though.

I agree with popo, I would run b100 but I have run b20 in stock 6.4s and new duramaxs, but all the 6.4 are deleted now, and didtn have the duramaxs to long.

i found this..reading up many say b20 is the most, ford recommends no more than b5.

2 years old so may have changed some.
B100 BIODIESEL FOR 6.4?

Ford's recommendation of B5 assumes that you're running a DPF and therefore have regen cycles. I'd stick to Ford's recommendation if that was the case. On a DPF-delete truck, I'd be comfortable with running B20.

Honestly, in a pinch I'd probably run anything. For instance (I notice you're in Houston) if we have a hurricane come through like Ike again, and I can't find diesel....I'll load the 'stroke up with WMO, WVO, and anything else I can find if its just for a few days to get by.
