Part of the reason bimmerfest and other forums recommend Total, Pentosin, LM and Motul is the group 4/5 base stock, but if I am not tracking the car and doing 5k OCI, does it even matter? I was initially leaning towards Pennzoil Euro, Quaker State Euro or Castro’s Edge on 5k OCI because it seems like they would be perfectly acceptable for my usage and interval.
Still nothing wrong with Pennzoil Euro, Quaker State Euro or Castrol Edge if they
come with either LL-01 or LL-04 approvals. I've never come across a single group
4/5 base stock Total. Not certain on Pentosin (though I know they do PAO based
MTFs), but very most LM and Motul with contemporary approvals are group 3.
Nothing wrong with that as long as it's accordingly priced.
I'd love to say don't disregard M1 ESP 5W-30, but it's no longer LL-04 approved.
Generally Mobil1 is strikingly short of BMW approvals.
I'd suggest Ravenol RSP 5W-30 (LL-01), REP 5W-30 and RUP 5W-40 (both LL-04)
if you like PAO/POE blend as well as Tungsten add pack, but they're quite pricey
compared to the above mentioned and probably harder to obtain, though they
aren't pricier compared to Motul (just majority group 3 so not worth the premium
IMHO).
I'd also suggest extending OCI to 7500mls if your engine gets up to full operating
temp on most of your trips. I prefer changing oil after winter season since dilution
is worst at that time.
