Quote: "I believe both Pentosin PentoSpeed 0W-30 and Elf Excellium Full Tech 0W-30 are
group IV.
These two are BMW LL-01 ACEA A3 B3 with the API SL GF3 rating.
Any oil with the single BMW Long Life (LL-01) ACEA A3 B3 are to be Group IV or V.
The newer superseded BMW LL-04 ACEA A3 B3 C3 can be Group III, IV, or V. The newer spec may be API SM GF4 rated."
also:
"(voll) Full-synthetic =
Grp IV and/or V
HC-synthetic = Hydro-Cracked,
Grp III
That's the easy way to tell
In Europe a full-synthetic can't use hydrocracked basestocks, but that's not how it is in the states as most full-synthetics are Grp III."
