Yeah I read something to the affect of Mobil 1 0w-40 is is Mobil 1's flagship oil in the European oil section here on bitog.

What is the issue with this engine?

No real issues but the M54B30 uses an AluSil block, these are extremely sensitive to some chemicals. Best to play it safe with these and leave the chemicals on the shelf, I've seen more than a few with damaged blocks due to improper service.

Probably the worst thing is using some combustion cleaners for a piston soak, if carbon is an issue then a gentle water induction if anything and nothing more.
Anything alkaline is taboo, Redline Sl-1 is fine for the fuel system.

Pretty much. It carries more approvals for high performance applications than any oil on the market. ALL current gasoline-powered Porsches and Mercedes-Benzes use it, and all gas-powered cars from Audi and BMW can use it as well. This includes everything from the entry-level commuters to the twin-turbo sports cars. It's one product that you can count on the manufacturer to get right. None of this necessarily makes it "the best;" it just makes it the surest bet for a lot of applications.

As Quattro Pete said, all you need to look for for your car is BMW LL-01 approval, which a few oils carry (including BMW's own 5w30, even though it doesn't mention that approval explicitly). All products with that approval should perform about the same in your engine. However, if it makes you sleep better to use something a bit more glamorous, then have at it.

Again, what do you intend to accomplish?

It's probably "OK" in the sense that it won't cause much (if any) harm. But why bother?

It's starting to sound like you just want to toss in an additive for kicks. If that's the case, stop looking for reasons. Just go with it and see what happens. It's your car and your money.
 
Why? These engines are good and don't have any inherent problems with the fuel or lube system.
Use a recommended oil and drive it, additives and chemical cocktails are not always a good thing.

The threat title is "MMO in BMW" and posted in the oil additive section, the OP did not mention anything about wanting to perform any service or solicit advise on same.
Just sayin.

What major service would be required at only 120,000 miles? IMO, just "clean" the engine.

You are correct. The OP may not be aware, as he stated be purchased the vehicle with no records. I was trying to be helpful.
 
Hey no problem, its just that once thing go in that direction things get real confusing and the original subject seems to get lost somewhere.
But yes your right about the OP may not be aware.

I know mineral spirits is used in many home brew aluminum polishes. I wonder about MMO because it has a lot of mineral spirits, what effect will it have long term on the cylinders?
I am not saying it is somehow bad for aluminum but if it is the basis for aluminum polish one has to wonder. I dont have an answer its just a thought and a question, maybe someone could chime in and shed a little light.

As i posted earlier these blocks are sensitive, its your engine and your money but i would research plenty before letting this engine injest anything other than fuel or BMW approved products.
 
Ahh gotcha then I'll be saving the mmo for the gf's car and lawn equipment

So what major service are you suggesting at 120k?
 
Hopefully you got an Owner's Manual with the vehicle. If not I'd get one pronto. I did a quick web search but didn't come up with a definitive answer for you.

Has your cooling system been overhauled yet? If not, I'd seriously look into it. Cooling system is a weak spot on these cars.

Indeed, My expansion tank cracked. Lucky it didn't overheat,
 
I remember on the old straight sixes we used to check the #5 and 6 cylinder for scoring. This was directly related to cooling system neglect, it was very common.
Leaking oil pressure senders were another common issue.
