But in defense the one poster about heavier oil, I did change to euro 5-30 at 500 miles. Then (after break in) did an aggressive track day, and two days of 1/4 mile drags with multiple passes. No oil low notice to date. I do check it occasionally (miss the dipstick). Have no idea what the situation would have been with original 0-20 oil, but i don't think driving it in sport all/most of the time would "normally" consume the oil the OP is posting. He may have an engine set up on the very loose side from the factory (depending upon factory tolerances).

But I really can't speak from experience with 0-20 oil in this engine, would be interesting to hear from others on this forum that run 0-20 and use Sport often, this is the first post i have seen of that much consumption in those few miles, is it a one off???

Lets hear from others running 0-20 (most of ya i assume) that drive this thing like it was made for.

Well I wasn’t aware of this and I can only hope the same didn’t carry to the S58 engine

[danallxt]

oops, in my post quoted above, i did NOT mean to say it is "common" i meant to say "come on man", guess i should quit with snide comments? sorry bout that. It's just that one poster can present a "problem" and it gets blown up as a potential universal problem, bad engineering etc.

Talked the service dept. They told me to top off and monitor. They don’t believe it is unusal for hard driving. So that’s the plan for now.

[danallxt]

Thanks for the update, i still want to hear if anyone else has had that consumption in 5000 or less miles. So far you are it. I see you are in Florida, so heat, high oil temps, and hard driving could do it guess with 0-20.

The last car that I owned that used that much oil in 5K miles was a '62 Oldsmobile that had almost 200K miles on it.

Guys what the fuck is a quart?

I live in Phoenix and use 0 oil in 5000 miles

2 quarts is not “topping off”. Losing 2 quarts of oil is absolutely, 100%, unusual and a sign of something terribly wrong

Texas here (40+ straight days over 100 degrees) and 0 oil consumption in 11,600 miles driving 90%+ in Sport

[danallxt]

All i can say to the OP is to monitor it frequently, and log at different mileage points what the electronic read out shows. (me I'd check every 1000 miles or less and log)
Who know,maybe it wasn't full at the get go, but i assume there's some automatic oil fill process at the factory but who knows what might have happened.

[Adam_G42]

Just to add, it probably won't be because it's turbocharged.... unless something is wrong.

Turbos are well engineered as a system with the engine during development, under extreme operating conditions to avoid oil being carried from the bearing housing into the compressor. Oil can be consumed "by design" under some extreme conditions if its unavoidable, but this would be very small amounts as has to be counted towards the emissions.

Even if it is oil coming through the turbo this could be because of air inlet or exhaust system having a higher or lower pressure drop then the system was designed for and not a turbo fault at all.

I would get it into BMW, no physical view of oil level and inconsistent digital readings and error messages means we are all just guessing.

That’s just bullcrap, done over 8k miles with a fair amount of hard driving - no engine oil used at all. Either the pre-delivery inspection failed to top up after it arrived from the factory, of you have a problem. I suspect the first, so topping it up and monitoring it should prove it.

Still haven’t returned from my business trip. Once I return and take the car out again I will monitor. To date, I never observed any smell of burning oil or any obvious leaks. Certainly no dripping in my parking space. So this one has been a head scratcher.

One thing that was odd was that I had to reset idrive to get a measurement of the oil level. Before the reset it would say that function not available.

Modern engines with tight tolerances like the B58 using 0W20 by design will suffer from oil evaporation. The higher and maintained revs, the hotter the oil gets, 0W20 with evaporate. This is well documented.
We all drive different so your effects will be different.

Do not switch to 0W30, this will cause undue engine wear. The oil is too thick at operating temperature for the chemicals that are in the oil to reach all the internals of your engine.
Engine design and oil design has changed A LOT in the past few years.
ALWAYS use the recommended spec oil for your BMW's. It contains the proper chemicals in the oil to keep your engine running to spec.

If you want a little insight in engine oil, check out "Which OIL should you RUN in your TUNED CAR?! We asked LiquiMoly!"

The above post is a perfect example of why ya gotta watch for typical internet misinformation, post presented as "knowledgeable information". The above post is total bullcrap and contrary to BMW's own specs.


To summarize, the 2023 US spec M240X BMW specs a LL12fe oil that is 0-30 and the Euro 2022 and 2023 specs for same engine also specs same. Note the US 2022 ONLY had the 0-20 spec, but folks noted the inconsistency with Euro specs for same engine, and BMW revamped specs in 2023 to be consistent. YA really wanna see the proof, go over to the oil section, and look for post #1 by poster Inc 235 titled something like, 2023 M240 oil spec, it has a copy of the BMW manual page that shows specs 0-20 and 0-30, so who ya gonna believe?
And yes, i do have a problem with folks posting misinformation posing as authoritative.

Your consumption will vary.

All I can say is that many of you suffer from the Dunning-Kruger Effect.
I have a few relatives that work at Steyr.
Then believe what you will.

Your entire expertise on the B58 engine has been derived from a mechanic you talked to and some random relatives that work at a firearms manufacturer.

[VegasG42]

So, is the 0w oil required for fuel economy numbers. Or is it because the B58 needs thinner oil to maintain the desired compression, and the turbo requirements? Or both

5013 miles atm no such message here. Seems if it were common would be a pretty large oversight to say change oil at 10k.

[Littlecoupe]

It's not absurd to think it was possibly underfilled at the factory. Not apples to apples, but my wife's new Mazda came with the A/C compressor basically void of refrigerant. CX-30's had that issue since 2021 based on the forums, seems Mazda or their supplier still hasn't smoothed out the wrinkles in the "just fill the damn thing" process.

As far as consumption, right in the BMW owners manual is the statement the oil consumption can vary, and in particular, based on driving habits (spirited driving). I would agree two liters/quarts before an oil change seems excessive in my unprofessional opinion, but it could be a combination of consumption and underfilled.

Don't forget the B58 seems to drink coolant. I had to put a lot in my F22 after only 30,000KMs when I had the low coolant warning light. Seems this is common for BMWs. No idea where it's going...out the cap, or out the exhaust...



Other note, OP, check under the hood. Maybe you have one of these in there, it would explain the oil consumption.

You obviously are speaking about yourself.
your statement

Do not switch to 0W30, this will cause undue engine wear. The oil is too thick at operating temperature for the chemicals that are in the oil to reach all the internals of your engine.

Is contrary to the BMW manual specs for that engine as i stated previously. Obviously you feel you are more knowledgeable than the BMW engineers that recommended ll12fe 0-30 for that engine.
