Say if you used the same brand, kind (syn/non-syn), or weight, OR ALL OF THE ABOVE for many years & miles.
I am wondering if say engine wear would increase if you took a motor, and switched off say M1/M1 HM over to a dino oil after 115k (180k on the ticker) or running M1 oil in it while you were the owner?
Or for purposes of debate, any other similar situation.
In my case this is a magnum V8 (roller, push-rod) but I am curious of the answers despite the specific motor because folks with OHC & flat-tappets might also wonder the same thing.
