Not me. And I’m even under warranty for the life of owning my truck. I guess it’s just partly a little bit of old school-ness but while having a little bit of mechanical background, I just can’t wrap my mind around change intervals on anything over 7,000 miles, I don’t care what that OLM says so mine gets changed every 6,000 to 6500. And that’s even on the PUP 5-20 and Wix XP filter.
I guess maybe those folks who run the Redline 5-30 and RP filter can get away with that since that oil has way more moly and zinc in it than most oils but for anything less than that, I wouldn’t advise it, personally. Changing your oil a little more often pretty much guarantees you’re not stretching your oil too far. And with all the talk of so many issues being said about the hemi tick and cam/lifter problems, I wouldn’t take that chance unless you’re running Redline. Just my opinion.
