Those of you who demand Redline oils should give superior used oil analysis versus M1 are going to be out of luck. It doesn’t. M1 is pretty good oil. Redline is better in some performance areas and weaker in others.
Use in a motorcycle is good example. M1 falls flat in viscosity retention compared to RL. However, M1 is good enough so it doesn't matter.
I think the internet rumor that RL doesn't hold TBN well is BS and repeated by the uniformed.
I've used 20 Dexsil kits to compare TBN retention between RL and M1. They both maintain TBN longer than most people are willing to leave oil in an engine.
If you really need Terry to give you some sort of comfort level for your oil choice, then pay him a few bucks. I've done it.
