[LLB-M2]

Hello

i want to change all liquida (oil) in my M2 LCI. Few days ago i allready bought an oil for another car, but now i dont need it.
Try to check if this oil is suitable for the M2 gearbox but i only found the origine Part number for oil, no specifications. I bought this oil:
https://www.ravenol.de/de/produkt/ge...vsg-sae-75w-90

Ravenol VSG 75W90 SAE

Is it Ok or need i another oil?

Best regards Christian

I think the original gearbox oil is GL-4 rated and 75W80 weight. So, no.

Why do you need to change it?

[LLB-M2]

I do this with all my cars. BMW says its a lifetime fill. When the gearbox is broken, lifetime is over.
Oil manufactors like castrol give their sealed products a best before time around five years. Every oil aiging, even when it is used, the additives wear also. The oil in my M2 is know five years old and around 50tkm in use. So its a good time to change it, also the diff again. Next change again five years or at 100tkm.

The best example.for a very fast wear of additives: My daily Bimmer E90 has a very sticky gearbox. Often first gear wont step in in first try. Changes the oil, it was a bitt better. Then fill in two portion of Liqui Moly gearbox additive. It was amazing, the first time it was like having a brand new gearbox and was very happy. But lasts only 500km (city traffic), then slowly start to get sticky again.

So, i guess its a good idea to change it time to time.

Check your clutch hydraulics. If there's air in the system the clutch won't fully disengage and give you the symptoms you describe.

Hope this helps

Gearbox oil is mtf -lt5 spec'ed which is a low viscosity dct fluid, hence why the gear box oils that carry mtf-lt5 specs are oils like redline dct, motul multi dctf. So I would use one of those oils, but I did hear some very very good things about redline's dctf so I would pick that one.

Thanks tonyour advisr. Bit it a known issue of the E90 gearbox. I bleed Clutch sereval times, removed CDV, get Clutchstop. Clutch is fine, its really the gearbox.

Thanks, will take a look to this oil.

As you can see I've had 3 M2's, and always have used the factory spec'd oil by Pentosin:

I just go to the Redline oils site and use what they suggest.

[LLB-M2]

That very interesting. I checked different german premium manufactors, and no one offers oil for M2 gearbox.
And in US market it seams no problem to get a compatible oil. 75W80 GL4 rated oil is available in Germany, but they dont give offficial specs as a replacement.
I will handback the not needed 75W90 and buy a SAE 75W-80 GL-4 oil.

[boostm3]

Not sure about 75-90 or 80. Bmw uses 75W-140 in the F87 M2

[F87source]

That's the diff oil, the gear box doesn't have a specific weight rating right on the package.

I think the OEM is pentosin so I'll check what pentosin says the weight is.

[M Fifty]

Well, as per my earlier post, several suppliers say it's 75W80.

An example: https://www.bimmerworld.com/Fluids/D...d-1-Liter.html

The actual MTF-LT5 does appear to come with only a 2-year warrantee interestingly...

A few days ago I changed the oil in my 6MT, Motul DCTF together with the ultimate shifter.

I guess it's hard to compare since you changed the shifter also, but any improvement from the fluid?

Nice!

I heard motul dctf is a decent fluid, but I also heard redline was even better. But I'm looking forward to hearing your opinion on the motul as we haven't had any m2 owners on here trying it yet.

The car has 28,000km i change the fluid to see what state the old one came out in, it came out a little grayish but nothing worrying, and also before the first gear was difficult to enter, now all the gears are very fine, I'm sure the redline is much better , in the next change I will try it

Yeah redline is Pao and ester based, while the motul is synthetic base which likely means some group 3's in there. So technically redline has better quality base stocks, but the major factor that influenced why I think it's better is the testimony from the m2 owners saying it was night and day vs. stock fluid and even fresh stock fluid. So I too will go redline likely next year. But note with heavy Pao and ester oils they oxidize easier so you'll have to lower your fluid change interval.


But good to know the motul is good, I might do that instead of redline if the redline oxidizes too quickly. I'd prefer to do changes ever 3 or 4 years (since I don't drive enough for mileage to be a limiting factor) so if it can't last at least 3 years that might be a problem for me.

Check HPL. Use BITOG15 code.

Ok I'll take a look. If it's not readily available it might be massively expensive to ship to Canada.

No it's not readily available.

Whats the part number/name for this fluid? I would like to see how much it costs. The mtl site isn't that user friendly for searching by car.

You can contact Dave at HPL through BITOG to talk options.
He even cooked specific oil for one BITOG member. Check with him what he recommends. I talked to him to try their product instead of Redline D4 (which I am very happy with).
