75W90 for manual gearbox
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 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. |

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.

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

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. |

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

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. |

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... |

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 Last edited by Track/S; 09-03-2022 at 01:37 AM.. |

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. |

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

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). |
