2003 6.0 superduty likes bio?

[pato.garza]

I just bought a 2003 6.0 superduty, and diesel is over $3.00 per gallon over here.

I'm asking if you could share any recent experiences you may have had using biodiesel, and if you make your own or buy it, from who, anything you may feel is relevant.

My assessment from the stuff I've found online, is that if you get good biofuel, it'll do fine, but that making a switch might loosen some garbage that may have been accumulating over time, so you have to change filter right away the first few times, and that after that inicial inconvenience it'll be all good.

your spot on! go for it.

i've gotten the impression that in the 6.0 that anything other than straight diesel isn't good for the injectors. am i misunderstanding something?

this is exactly right. Be picky about the quality of the Bio you buy and who you buy it from.

Yes, this is not true.

Clay is correct. get GOOD bio, pump bio should be ASTM standard and fine. 6.0 injectors are more sensitive to fuel quality than say the 7.3. dont let that scare you away, as bad D2 would screw up the injectors just as well.

sorry to hijack thread but say i go to a pump and get bio are there any advatanges or disadvantages to running it? like better mpgs? affect the power at all? what about using it with a tuner?

[ridiculously_necessary]

youll get mixed reports about power and mpg's. from what i have read, pump bio gets same power and mpg more often than home brew. bio is a good solvent and lubricator. so you truck may quiet down, and may see a couple dirty filters from the tank and line cleanout.

no disadvantages other than the gel point that i have read about from ASTM standard bio. i would think at most you would see a one or two mpg drop.

so if i run a tank of bio it will clean my entire fuel system?

[ridiculously_necessary]

entire fuel system? dunno, and probably not. i doubt it will clean 100% and probably not in one tank. thats just my guess. it will however knock crud loose. hwo much jsut depends. some guys get clogged filters the first tank or two. other guys dont see filters much more dirty than when they ran D2. so we always reccomend keeping a spare on hand in the case of the first event.
