New Duramax Question
Hey All, I'm considering a new GMC 3500 single rear wheel diesel and have never owned a diesel before. How often do you have to change the fuel filter on a Duramax? Every 5000 miles? 10000 miles? M...

I've not done an oil change on my new truck. Looks like I'll be able to go about 5000 miles though, based upon the readings on the dash and current mileage. As with your family car, every time you change the oil, get the oil filter changed too.
If you are buying brand new, GM (had) a deal going on when I got mine last April, that oil and filter changes are no charge for like the first 50,000 miles or something like it. It was pretty awesome! But they do want the "oil life" down to 25% left or less. My last truck I let it get down to about 3% or 4% and then had the oil and filter changed. It did run a little 5000 miles between changes.
Personally, I'm not so concerned about filter and oil changes, as much as I am concerned about DEF fluid. I freeked out when the warning message came on and said I had only about 150 miles left. We found a GM dealer and I bought the DEF fluid (because we were on the road en-route to a State Park), said my truck should not have needed any for quite a while, so it's possible the dealer we bought it from did not fill it before we took delivery. It's filled now!
