Friends, I know manufacturer oil change specifications aren't subject to owner opinion or rationalization, but I just have a hard time getting past the time interval. In all the vehicles I've ever owned, I never change oil based upon time, only miles. To make my point, my 2017 Ram 5500 sat on the lot for over a year, yet the dealer did not change the oil a single time. I know this is a stretch, but makes the point. I'm on the crossroads of deciding on this now. I like 10K on the oil changes and for me that can be from 6 months to 15 months.
I have never had an engine failure, never had a vehicle use oil with over 200K miles on the clock, so just changing the oil based upon time interval just doesn't work for me. I know, it goes back to my opening line "I know manufacturer oil change specifications aren't subject to owner opinion or rationalization," but that hasn't stopped me before and won't stop me now.
Cheers, Ron
