Hi folks,
I am new to this forum so excuse me if this topic has been overdone. I bought a 2007 Silverado 2500HD in January with the Duramax LBZ and the 6 speed Allison. I know the truck was built in early 2007 and I think it was designed to run "low diesel" instead of "ultra low sulfer diesel". The air cleaner has a sticker on it that says 2006 model year and the fuel gage does NOT have the "Ultra-low sulfer diesel only" label on it. I'm thinking this was a late 2006 engine put in the early 2007 truck. Does this mean I can run both low and ultra low? Should I only run "low sulfer" ? Is there any advantage to running low versus ultra low? The dealership service department say "All 2007's run ultra-low". I think mine might be an exception. If anyone can shed some light on this I would appreciate it.
Thanks
