biodiesel and mileage

[knisleyjoey]

Hello, i have a 2004 6.0L and have been considering using biodiesel. Anybody use b5? I have a warranty and do not want to void it. Any good or bad results? How is the mileage and how about the cost? Also, does anyone have any good tips for improving all around mpg's in the 6.0L? Thank you for any information!

I've been running B5 in my 95 7.3 powerstroke for over a year now, seems to love it. The local truck stop sells it for the same price as their ULSD.

Getting ready to step up to B20 I think. It's available semi-locally, a little out of the way, but only maybe 5-10 cents more per gallon. Should help a lot with lubricating issues and not to mention drop my emissions by about 14 percent. Nothing wrong with that :-)

Do some research, I'm pretty sure most diesel engines are all certified to run on upto B20. Not positive, but pretty sure I came across that somewhere. But if your still under warranty you obviously want to do the research and be for sure.

Good luck.

Thank you cark. Ive read that going ober b5 would void the warranty and thats the last thing i want to do w/ a 6.0L!

B5 youll be fine. When your warranty is up, you can start running a much higher blend up to B100 in the spring and summer.

Loves next to my house sells B5 so that is what I put in my tank. All the studies say B5 is enough to lube the injectors but I still hear a huge difference when I put 1oz a gal of 2 stroke in there. At least with my truck, b5 is not enough...

I ran b100 for a bit but did not like the way it felt. There was a bit less power (really felt it pulling my 12k 5er) I settled on about b50. that seemed to be the point where the power startetd to fall off. Now that I run SVO I feel NO difference on b5 (from loves) vs 100% VO.
