Fuel Contamination??

[Joelbeal]

What luck. My 2006 2500 Cummins (with only 2500 miles) suddenly started running like crap. I am leaving soon for a 4000 mile trip, and the dealer can't get to it. Furthermore, he thinks (and I agree) that I picked up a batch of contaminated fuel (Flying J Truckstop in Dallas). He says he's seen a lot of contaminated fuel problems in the past, just use PowerService 9-11 and work the old fuel out.

Low power, sometimes but not always. Sometimes misses when I first start it at all RPM's, but as I drive it it gets better until it only misses under a load at about 2000 RPM and higher. It started within 20 miles of my last fill-up which was on an empty tank. I've had a Dodge Cummins for 9 years, this is my first serious problem with fuel contamination.

No water is coming out of the fuel filter drain. I am on my second filter in 300 miles. I added enough PowerService for 50 gallons to my 34 gallon tank. Seeminly no changes in the condition. I am down under half a tank now.

Am I going to harm the fuel system? Should I just drive the truck and hope that the fresh fuel will straighten it out? Should I double up on adding PowerService to the tank, and should I dump some in the filter as well? Is there a better/different chemical additive out there?
