BMW B58 Engine oil

[1JZ_E46]

Thanks for the clarification Oil_Film.

Also, it's important to remember that the LL-14 standard is purely motivated by car manufactures doing anything and everything to meet the CAFE standards. It WILL compromise engine protection to some extent, albeit small. LL-01 oils have always been considered the premium of engine oil, so since it's allowed, I would use that.

Jeez one mention of Trump in a non-political fashion as it relates to regulations and it's instantly censored here. Thought bitog would be above that.

I haven't seen it written anywhere that cafe drives these standards. I'd love some links.

The US isn't the only place in the world that uses oil in vehicles and wants better FE and less emissions, etc.

My point was that the push for lower viscosities is driven by a desire to increase fuel efficiency, not for better engine protection and longevity.

My point is that technology advances and it isn't driven by one goal. Engineers always push to improve all aspects, is possible. Car longevity in the US is at all time highs right now and keeps improving.

The goal is fuel efficiency, without compromising engine wear. The goal is not better engine wear, without compromising fuel efficiency. There's a difference.

The goal is to meet certain fuel efficiency targets AND certain wear targets (and cost targets etc. etc.) at the same time. And both are, on average, increasing over time. Simple as that.

If we trust your list (Turner's really), then we see the BMW 240i B58 can't use 0w20 (only LL-01FE 0w30 or any LL-01 oil).
A 2018 BMW 240i B58 is the subject of this thread.

Wouldn't it be nice if BMW actually put 0w20 as an option on the B58 in the Owner's Manual or from some official statement from BMW?
Otherwise, I guess we have to trust what aftermarket parts peddlers are saying.


I got it from here, should've mentioned that. Good to know it came from Turner though. Certainly they are a well respected BMW specialist and one would certainly hope they posted the correct list. I'd imagine they have access to many of the factory oil guides etc.

In fact visc is the starting point for approval.

To sum it up:
LL-01: HTHS >3.5 in a 0w30, 0w40, 5w30, or 5w40
LL-01FE: HTHS ~3.0 in a 0w30
LL-14FE: HTHS ~2.7 in a 0w20


What I stated was, in regards to LL-01, to the consumer/user- an LL-01 approval is what really matters. Viscosity/grade is secondary to that since multiple grades are available and approved by BMW. Of course the spec is dependent upon a certain grade(s).

Ah! Very good to know. Thanks for the clarification.

It is true you can use LL-01 in most U.S. BMW gasoline engines, with a small loss in fuel economy, cold cranking flow, and peak power due to the thicker oil.

From the 2016 340i B58 Owners Manual posted earlier, that model year, and maybe 2017 and 2018 B58 engines by assumption, can use either LL-01FE and LL-01, clearly from the Owner's Manual.


The times I've seen LL-01FE as a recommended spec, LL-01 has always been listed as an alternative or suitable spec oil to use.

Just to close out the thread, I first changed the oil + filter at 1200 miles: LM 5W-30 and a Mann oil filter. Subsequent changes were the same. My next change will be BMW Twin Power Turbo 0W-30 (from FCPEuro) and a Mann filter. I've considered Ravenaol FES 0W-30, but I think the TPT oil will be fine.
