While they're not usually the best, they land favorably in almost all the tests. IMO, the ball bearing test is nearly useless as a measure of anything inside an ICE.
What the heck is up with Redline at TEOST?? I guess it achieves it's low NOACK by just turning solid instead?
The cost comparison chart at the end seems like total nonsense to me.
I avoid dexos1 if possible as TEOST precudes some very good antiwear compounds to achieve a pass - so - A Clean turbo bearing at hot shutdown and a seized engine. Not a compromise I'm willing to make. Somehow BP's Magnetec seems to get good power performance and a clean motor at the same time.
MAGIC!
Try QSUD 10w30 VS 5w30 the 10w is a absolutely stunning performer in a NA motor. It is NOT Dexos.
I'm kind of confused, you avoid Dexos gen1? Meaning you use oils that are not Dexos1 approved, because they do not protect as well as non-Dexos1 oils?
Just curious because in my "fleet" I could care less if it's Dexos approved, maybe the Matrix would be the only one I'd consider relevant to needing the Dexos approval, but even that may be a moot point.
Ive recently run ( w/in last two years) Pennzoil SS Dexos1 5w30, Pennzoil HM 5w-30 , and QSUD 10w30- The 2 Shell products that were NOT dexos was preferred by my car and the snowblower. Just qualitative assessment.
You KNOW they had to back off on many earth metal compounds to pass the two teost rounds and they can be traditional anti-wear compounds like Moly. This includes the past GF-5 product lineup minus 0w20 where the Japanese industry wanted and exception in GF-5. It may be more at Viscosity with Dexos than lack of traditional antiwear adds. My Nissan engine likes a 30 close to the 20 grade upper margin.
