BMW B58 Engine Oil Recommendation

Leaning towards Castrol 0w-30 Euro as it meets LL01 and easily available with good specs. Or Liqui Moly Top Tec 4600 as it has similar specs (LL04 though) and can easily get from FCP. Motul seems a bit harder to come by (which would be my preferred choice).

Also curious about what's best for DI valve clogging and what to watch out for without compromising engine protection (first DI engine here). Thanks again for all the info!

0Castrol Edge 0W30 is not anymore LL01. All 0W oils are not anymore LL01 and LL04.

Generally speaking oils which fall under ACEA Cx (ex, LL04, 229.51) category use a different ad pack which will result in a reduced rate of accumulation onto the valves vs ACEA Ax/Bx (ex, LL01, LL01FE, 229.50, A40, 505, etc) oils.

Of course the design of the PCV system and valve timing play the primary role in how quickly buildup has an impact on engine operation. I can really only speak for BMW engines and it appears that aside form the N54 (2007-2010?) there is no "build up issue" with BMW DI engines. In the US BMW has, for gasoline engines, stuck with ACEA Ax/Bx oils since inception. The N55 has a 100k mile interval/check up and even at that mileage the buildup is not impacting engine performance from those who've taken a peak. Basically what I'm saying is that it should be at the bottom of your list of concerns.
 
Per BMW's technical documentation system (TIS), LL-01, LL-01 FE, LL-14/17 FE+ are listed as compatible with the B58 - with 0w-20 17 FE+ as being the 'recommend' oil.

This could be due to CAFE/EPA considerations, or due to the fact that 20 weight warms up quicker and flows more quickly to lubrication points - especially during a start/stop cycle.

It also states that LL-04/12 should not be used in North America for gasoline engines.

No, a thicker oil warms up quicker than a thinner one, plus they all “flow” the same to the lubrication points as long as they can be pumped.

There is no need for "could be." It is 100% the case. There is no any doubt.

Is there a way to access this TIS or are you able to share?

Sounds like I'm narrowing it down to LL-0X (01 or 04) with a ACEA CX with a 30 or 40 weight. The "recommended" just seems way too light for my climate and driving.

Why isn't LL04/12 recommended for NA?

It mostly stems from an outdated concern that North American gasoline had a higher sulfur content. This is no longer the case since the EPA Tier 3 program has been in place.

While it is technically possible to get higher sulfur content in one batch of gasoline even under the new rules, it would not be constant and would not materially affect the oil TBN in a significant way. It is safe to use Longlife-04 oils in North America.

Especially for a shorter 10,000km / 6,250mi interval.
 
So many variables to consider when it comes to selection.

What evidence is there (if any) that NA fuels have high (reletive) sulfur?
