Does anyone know of any higher HTHS xw20 oils besides redline? Preferably in a high mileage formulation? Being that redline is ester based would it serve as a “high mileage” oil?

Just want to get the thickest 20wt possible. Unless there isn’t a significant difference between say a 2.6hths 20wt and 2.9hths 20wt.

Some great & affordable 0w30 lubes out there - that will be real close to an expensive thick 20.

Pennzoil Maximum Power 0w30 has a kinematic viscosity of only 9.6 at 100 degrees. That's very close to the 20wt range.

What I don't understand is why it only has a flash point of 204 C. That's among the lowest I've seen with a full synthetic. Pennzoil Platinum 0w20 is another that is at 204. Hmmm.

Use a thin xW-30 instead of a thick xW-20 ... more choices, and probably cheaper.

A VW 508.00 or BMW LL-14FE/LL-17FE oil. Be prepared to pay, as none of them are "mainstream" and Castrol/XOM/SOPUS can't be bothered to market a "Euro" 0W-20.

I liked the redline oil 0w20 as it was very shear stable,quiet and still offered better performance than oils in a grade thicker. Lots of BRZ and FRS guys run it even on boost. It's about the only 0w20 that would give me any confidence to run on a track. Ran it over 150,000 miles before moving up to a 30wt as my rings are letting a bit of oil by. It's going in the 2020 CR-V after I get 12,000 miles on it.

If you guys know any other thin 30wts let me know. Anyone know the HTHS of Castrol EDGE High Mileage 5w20? It’s 9.0cst at @100c.
