I am thinking about selling my 2004 6.0 Ford, and buying a 2006 Chev.duramax. I have not been on the chat for some time,and was wondering if there are issues with this motor and Bio? I have been using about 60% in the ford for about 18 months.Any info would be appreciated.

We run B100 in one 03 powerstroke and an 03 and an 04 duramax, all have 50-60K on bio with no issues, the worst thing about the duramax is changing the fuel filter, it is a royal pain in the ass.

A friend of mine runs a two tank wvo system on his 04 duramax. He has put over 100,000 km since he started running wvo. He had to replace all his injectors, but the mechanic told him it was just due to the fact that they had over 250,000 km on them. other than that he has had no problems.

2004 Duramax, 15k on B100. If you ask me, it runs better on B100 than dino diesel.

Not to argue fabricator but personally I don't think the filter change is that bad. The worse part is removing the inner wheel well and even that ain't that bad with the right tool to pull the pins out. I've done it a half dozen times and can do the fuel filter, an oil & oil filter change, and an air filter change in less than an hour. Good luck.

Remove the wheel well? I remove it from the top, ten minutes tops. Pull sensor, twist off, exchange senors, fill filter with bio, twist on, insert plug, two cranks and go for a ride. Air and oil take even less time.

One thing I do know is the O rings on the duramax primer pump will swell up eventually and cause it to stop working if you run B100.

My primer did give me a problem. It was leaking fuel and would not stay primed. I replaced the
o-ring that seals the pump housing with one from the auto part store that was comparable. I can't believe it actualy still working. There is a guy that remanufactures them and says they will hold up to any kind of fuel. It's not cheap, but compared to the price of diesel, it's worth it. I found a complete filter assembly on ebay. When it is time to change the filter againi I'm going to install the one from ebay and then send off the other one to him to rebuild. Check it out:

Good luck.

When we change the filter on my dads truck we just crack the air bleed bolt and stick the vacuum pump hose on it.
