So doesn't that mean that a standard BMW-branded 0W-30 could have nearly the same HTHS as these 40wt oils?
Mobil1 FS 0W-40 3.6
P Platinum Euro 5W-40 3.6
Castrol Edge 0W-40 = unknown but I read somewhere 3.6
If HTHS is a good barometer for how the oil will protect on the track under severe use wouldn't bumping up from BMW's 3.5 to +/- 4.0 be a good move? The heavier oils also seem to have lower Noack numbers.
Redline 5W-40 4.4 (6% Noack)
Redline 0W-40 4.0 (9% Noack)
Motul 300V 5W-40 4.1 (8.6% Noack)
Millers CFS NT+ 5W-40 3.97
**wildcard with unknown HTHS but reportedly an impressive oil for track use
I am really trying to not wear out my welcome here by beating a dead horse but these questions keep lingering
0W30 BMW TPT is not standard BMW oil, it is an attempt of BMW North America to address short grocery trips that Americans are known for.
LL01 FE is older spec. but not widely used. In Europe LL01 was go to oil until ULSG was introduced when LL04 became and still is oil of choice. Even new B438, 48 and 58 engines are recommended for LL04 in Europe.
You are too hang up on these oils and HTHS. FYI, Castrol 0W40 has HTHS of 3.7cp. Redline looks good on paper, but it is not approved, regardless what Redline claims. Is it good oil, yes, but there is that lingering question of why if it is that good, Redlne developed another oil to get approval which is mediocre at best?
I told you already that my choice would be Castrol 0W40.
