I have a stage 2 m340 and I was wondering what type of oil I should use? before I would use molly 0w30. should I change that ?

Boy I wouldn't run a 0w30 or lighter oil in these cars unless it's sub-zero all year round.

I'm in Australia and BMW state 5w30. That's the lighest oil I'd use. The only reason BMW states a 0w20 or 0w30 oil in some countries is for emissions, but it ain't doing your engine any favors.

I'm running MHD "Stage 2" and have a dp, and colder plugs. So nothing wild at all. I continue to run 5w30 LL01 oil which is factory spec for this car here.

I have a 2020 M340iX.

I read that these ones are more for the Gen 1 B58 and that ngk 96206 are the ones for the B58TU.

Did you know? Did you do any logs? I'm curious cause I done the same and maybe thinking switching for the right ones. They actually go deep 2 mm in the combustion chamber but does it make a difference.... Thx

[cyam]

From my understanding they are the plugs for the TU.
Yes done logs, all good once I got the fuel and tune right. I am in Australia and fuel quality is bad.
I gapped slightly wider at .026" than the 0.022 tuners say. But narrower than the factory 0.030"

Interesting, I'll do some logs later to see and find the sweet spot and if you have some time to kill I suggest you that video

And thanks for your input mate! G'DAY

I removed a spark plug - the NGK 94201 I am currently using and compared side by side with the OEM/BMW/Champion ones I replaced.

The photo shows they are exactly the same. Same length etc. Only difference is the NGK has the electrode slightly more exposed, because thy are slightly colder plugs.

Alright so not that dramatic, thx for taking the time, I took some logs yesterday and everything seemed okay, so I'll leave those plugs in and I guess I'm ready to get tuned now.

I have been running 0W-30 the whole life of the car besides one oil change using 5W-40. Car is sitting at 53K Miles, and it ate through a quart with the 5W-40 between my oil change intervals where as 0W-30 I've never seen it go down more than half a quart between oil changes. I have also been tuned since very early on in the cars life, oil always comes out clean even when going 5-7K between changes. Doesn't matter if its 20 degrees out or 120, car has been through a wide range of climate zones and has virtually no issues regarding oil consumption or wear material in the oil.

I’ve got a 2020 m340i. I need to get my spark plugs changed but the website says these won’t fit ? But I keep seeing others say they are running the same exact ones. Can anyone help??
