Thanks for the info., so I should be able to run alternate fuel?
The reason for the question is, the guy"s at Diesel Craft have a costomer
with an 07 Duramax who reported when running alternate fuel got an engine
ck light and an engine error code, no specifics.
I also have been told by a person who works for a GM dealer that the 05
Duramax is the last year that one would be able to use other than store
bought diesel and I am just trying to confirm what I have been told.

I don't think you got the right story from him. I believe he is referring to the '07 and up having a DPF and high amounts of bio would maybe cause soot to not be completely cleaned out of the DPF on regen. Prior to '07 you can pretty much run whatever (within reason).

Thank's for the input Mike!
You know, this is yet another good example of GM dealers running their mouths on something they have absolutely no clue about.
GM says we can run 5% bio. Most stations are 10% mix, much like most gas stations these days who run 10% ethanol.
You can run 100% if you want. It may require more filtration or maybe even less but its certainly attainable. Many people have done it and havent had any problems. I've also heard of people running bio and having gelling issues. Up north, you really cant run it for the majority of the year because the gelling point for bio fuel is around 35 degrees. Put a bottle of this stuff in your fridge and you'll see it turn to jello. You being in Arizona, I dont think you'd have a problem.
Also, bio runs less BTU's so it dosent produce nearly as much heat when it combusts, giving you less power. Many people just turn up the knob on their tune to compensate for the loss in performance.
The new body styles with the DPF on them are really sensitive to many modifications. Its like your ex wife that just wont leave you alone. She was good for a couple reasons but the bad far outweighed the good. In turn, you're much stronger without her, with less b.s. and less headaches and you effectively run more efficiently.
TW, if you're gonna run bio, just keep your fuel filter changed at regular intervals. Bio tends to really clean out your system after a couple tanks.

To add a bit:
I run B20 (pump says B20 then the fine print says somewhere between B5 and B20). I like the idea of the extra lubricity BIO adds for the pump.
It's also a way to reduce the need for mideast oil but that could easily be rectified by just DRILLING for what we have here...:mad2:
Nick is right about the lower performance and I see a loss of up to 1 mpg with BIO. The price difference is usually not worth going to straight #2 for me but that's just because of the stations I pass.
The BIO I run is guaranteed for -20* in winter but I still run additive just to be sure.
When I started running it after many miles, the first couple of filters were pretty nasty at 10k. Now I can stretch it to 15k but don't usually go that far.
