BMW B58 Engine Oil Recommendation

[edyvw]

After digging deeper in this rabbit hole of finding the right oil for my NA spec 2020 BMW M340i, I still don’t know which oil to use. I’ve had oil consumption issues so I switched to Liqui Moly 5w40 molygen. I’m on a very short OCI @ 2500 miles.

I am catless downpipe with a stage 2 tune and run an ethanol blend. I daily my car and I have short trips to work during the week but drive very spirited on weekends. LA climate.

I’ve heard of people recommending LL04 oils. I am LL01 so I’m not sure if I can use that? I want the best oil for my car. I’ve also heard to use Motul Xcess gen 2 5w40. Price is not really a concern and I don’t mind ordering online.

Thanks

Ethanol blend, go for thick W40 or W50.

What brand should I get? Also, what do you think about Motul 300v ? Or AMSOIL? Even tho I’m tuned, I’m still on stock turbo and stock engine.

@PortimaoG20, post some pictures of this beast.

Driving spirited with turbo equals oil consumption in many cases. For me thats the only time I actually notice any consumption at all.
Any 5W40 with API SP or Euro spec A3/B4 should be fine.

Makes zero difference at 2.5k OCI.
New software barely counts as tuned imho.

Lol. A “tune” in the racing world is a recalibration of the ECU. I don’t understand what you meant by that. For my car to go from 382 whp to 510 whp with a flash tune and some ethanol what is it then if it’s not a tune?

Tunes are done on a bench or rolling road for your specific setup.
Not with a laptop that loads new software pre-made for all engines. That would be called "optimized software" on this side of the pond.

We call it a dyno tune or a street tune. But thanks for your insight.

Can you look at these data sheet and tell me what you think about this oil?

Ester based oils don't mix well with alcohol.
Try BAS oils from HPL. They will respond to alcohol well and they are streetable racing oils.

Not big fan fo Liqui Moly. That is strictly GrIII oil, nothing special. You are better off with Mobil1 5W40 from Wal mart.

I would go with motul specked for your engine. thick oil for 0W30 and good level of additives

here is VOA

IF LL01 and LL01FE is at question, and willing to pay for Motul, I would go Castrol Edge 0W30.

I don’t have a BMW but have a B58 in my Grenadier. It came factory with 0w20 oil and I noticed a definite difference going to QS Euro (LL01 spec) 5w40 oil. A bit mind blowing how much smoother it runs.

any particular reason for that? Castrol Edge 0W30 HTHS 2.9, Motul 0W30 ll01FE HTHS 3.4

He's referring to Castrol Edge Euro A3/B4 0W-30 which by virtue of carrying LL01 and other Euro approvals must have HTHS >=3.5. This is a datasheet from 2014 you linked and it wasn't even accurate in 2014.

Because it is very shear stable oil, low Noack, etc. etc.
Castrol Edge 0W30 A3 PDS

By the way, that Motul is old stuff. New LL01FE Motul is 0W30 and HTHS is 3.
