BMW dealers do all kind of stuff. And yes, they are all gun hoe on fuel efficent oils.
Your engine is built with LL01 in mind and in your manual you can find where it says that you can use LL01 if you are concerned about warranty.
You do not have to change oil at the dealer.
BMW recommends LL-01 FE 0W-30 for this M engine. There is
no mention of LL-01 anywhere in the owner's manual.
2019 BMW M4 owner's manual
LL-01 FE is basically ACEA A5/B5 with TBN ⥠10.0. Therefore, I think any flagship ACEA A5/B5 5W-30 would do well in this engine. Mobil 1 5W-30 and Mobil 1 Extended Performance 5W-30 are both ACEA A5/B5 and have TBN ~ 10, and they would be excellent choices for this engine, the Extended Performance version being even better.
BMW makes a lot of money from dealer-provided services. I wouldn't hesitate using Mobil 1 FS 0W-40 and Castrol 0W-40 for LL-01, Mobil 1 5W-30 or Mobil 1 EP 5W-30 for LL-01 FE, and the PAO-based Mobil 1 EP 0W-20 for any Euro-OEM or ACEA C5/C6 0W-20 spec. These oils are very cheap at Walmart, and I bet they outperform the BMW "Twin-Power Turbo" OEM oils in any application.
S55 engine is developed from N55 engine. Again, stop with your "recommendations" that are based on your Google knowledge. N55 engine as well as it's cousin, S55 engine is developed around heavy oils, LL01. If owner is going to use any other oil, it should be LL01, and not Mobil1 Extended Performance. BMW NA only recommends FE oils in last few years. LL01 oil was recommended before for the same engine. Change is due to CAFE requirements and does not have anything to do with engine design:

Also, LL04 (HTHS above 3.5) is only recommendation for S55 engines in Europe.
And no Wal Mart oils like EP etc. do not outperform BMW TPT. You bet wrongly.
Again, stick to Toyota.
You said the OP shouldn't use LL-01 FE in his engine and the dealer put the wrong oil by using it. Should people follow recommendations by an accountant like you with minimal technical and scientific understanding of engine oil
instead of following the recommendations in their owner's manuals?
Engines have many versions. You don't know if the newer versions have better oil cooling among other things. Most new BMW, Audi, Jaguar, etc. engines spec 0W-20, and there is engineering research and development going into that.
The oils I suggested are
very similar to the their BMW OEM counterparts. Castrol and Mobil 1 are
not "Walmart oils." You can shout as much as you want that BMW OEM oil is better than Mobil 1, but you have zero backing
and zero understanding of it.
Driving a BMW makes you as much an oil expert as using an iPhone makes you an electronics expert.
Stick to accounting.
