Which immediately invalidates your claims as to it being energy conserving..... Since those oils are found with an HTHS of ~3.0.

BMW 5W30 exists in a few countries, most use(d) M1 0W40, most still do. Using 5W30 here voided the E46 warranty at the time.
Using BMW's branded 5w-30, which is an LL-01 approved lubricant, would void your warranty? I can understand that argument with respect to your OTS EC 5w-30, but not with regards to a Euro-spec 5w-30, one which is extremely close in viscosity to the light 40-weight oils that are also spec'd for the application and carry the LL-01 approval.
LL-01 is LL-01, no matter what country you are in. Though I understand that it is likely harder to get a "Euro Spec" 5w-30 in places that aren't Europe
We have very few of them in North America too. But Fuchs, TOTAL, Liqui-Moly....etc all make LL-01 5w-30 and in may cases 0w-30 lubricants.
A quick bit of searching myself does show that BMW dealers in Australia generally used M1 0w-40 up until the "Global" deal that BMW established with BP a few years ago. So your argument that this was the oil used holds water. However that reinforces my stance that your VANOS issue was likely a player in the compression test numbers and not some cleaning of the ring-pack area, as my experience with this lubricant shows it to be extremely good at keeping pretty much everything clean. But it certainly isn't going to help with degraded seals, which is where I'm sure the ARX helped you.
