....Interesting...that's news to me.....
Years ago I hired a chemist for a project (spinning hollow fiber) that did his masters on Mobil 1 development stuff; we had a few interesting discussions about syth vs. dino oil. I've pretty much used Mobil 1 100% since then changing it every 8000 miles (whether it needs it or not
). I use Rotella in the motorcycles since it has a few specs that meet wet clutch criteria.
I find these oil threads almost as interesting as brake discussions, as it seems that oil-related failures are few and far between as long as the oil is changed at a reasonable interval. All that being said, we had a trooper that toasted a rod bearing right in the middle of Yosemite years ago. Drove it back to So Cal with a super loud rod knock successfully.....
