FYI: I hope noone ever considers running off road diesel in a new 6.7 Cummins or you will be walking.
Yep, even some of the "on-road" stuff - just ask Hemigeno.
It took nearly 1k miles for my 2007 truck to "clear its throat" and start running right again after fueling up in Zanesville, OH last year. I thought I was gonna be walking there for a while, and that was after getting fuel from an Exxon/Mobil (name brand fuel) pump WITH the correct Ultra-low Sulphur sticker. Then came a trip to the dealership once I got home to get the computer reset and remove the error message from the console/display.
These new cats just will not handle anything but good-grade ULS, and you still have the chance of getting a bad tankful like I did. That will be the case from here-on-out though with any new truck, so waiting probably won't help the situation any. The only thing that will change is that more and more stations will be carrying the ULS fuel. I was absolutely amazed at how few
Pennsylvania stations carried ULS last summer, but I'm sure (hoping) that has changed since then.
I don't like paying taxes any more than most folks, but I hate walking even more...
Sorry to hear about your troubles Geno. I had heard of troubles when guys tried to chip the new ones also. I hope your truck don't let you down any more or you might have to put a hitch on your Hemi Charger to pull the Daytona.
