All VW 502/504 approved oils are either light 40-grade or heavy 30-grade, borderline 40. So even if that 30-grade oil shears a bit, it'll still be a 30-grade.
In any case, it's the HT/HS viscosity that's more important than the 100C kinematic viscosity.
Unfortunately only PU posted their HTHS none of the others did. Since they all pass similar certs I am sure they are all very close to each other.
Are the oils I posted group 4 or 5 to anyones knowledge?
I would love to run redline to be honest I love that stuff but with no low to mid SAPS that I know of or VW certs it isn't doable while under warranty. Silly huh?
