OEM BMW Fluids

[KhanArt]

Hey guys need some help,I am going through all my fluids again and it seems things have changed/no longer available since the last time I did this years ago?

Hopefully this information all in one place will help others out as well. I wanted this only to be OEM fluids unless their are blessed, tested, and proven alternatives out there. I'll try to complete as much as I know but please add/correct to this list.

*Please update/correct the info below with the correct quantities needed and/or new part numbers.

TLDR - Where are you buying your MTF-LT-2 fluid from and what is the new part number? Also what are you using for your power steering fluid that specifies ATF only, part number please.

For PS fluid, you can use any Dexron III (or Dexron VI, which is backward compatible) ATF from the local auto parts store.

(I had a bunch of leftover Havoline synthetic from another car that I use).

ATE Typ 200 is more or less the same price as OE BMW fluid but might be locally available in a pinch. If you're driving on the street any DOT4 will be fine, even auto parts store brand. Freshness is the key there.

Here's a thread on the trans fluid that will answer your questions to avoid repeating the same discussion here: https://nam3forum.com/forums/forum/m...smission-fluid

ATF is ATF is ATF. Anything Dex III+ (ideally synthetic) is fine, higher quality (specifically higher boiling point?) fluid may be better for track use since the PS fluid can get pretty hot.

I've always used OE BMW coolant in all my BMWs. $20 for a gallon of concentrate? No reason to use aftermarket and worry.

You can still get oe Bmw mtf-lt2 from ecs.

Somebody on the orig M3forum had a ton of MTF-LT2 as well. Kaiv? I picked up a pair at a local auto parts store right as it was becoming unobtanium, and had recently changed it before that so I'm good to go for a few years before I'll even need to use it.

I got 10 liters from Kaiv a year or two ago. I believe that the 5 liter jugs are still available at Canadian BMW dealerships, may be worth getting someone to ship you some if you know any canucks.

Also remember reading a while ago that the same exact transmission fluid is used in a Hyundai, so Hyundai dealership service deparments have barrells of it and you can buy it from them. Someone back me up on this?

Thanks! This is the confirmation I was looking for on the PS fluid. I'll just use a quality synthetic Dex III ATF fluid.

It must be the 5 liter jug that is no longer available.. at least on ECS.

Perfect, So I guess you can only get it by the Liter now... 3 Liters about the correct amount for a drain and refill? I bought the 5 Liter jug when I did this years ago and have about 2 liters left that is why I say that but I could have gave some to a friend..

Thanks again.

2 liters for transmission fluid.

Thank you

MTF-LT2 was replaced with MTF-LT3. you can use Pentosin FFL-4 DCT fluid as well.

[macaroni86]

I remember reading on M3F about Pentosin MTF-LT2 still being available at NAPA.

LT3 is for other transmissions.

FFL-4 is the current official recommendation, but also certainly less specific to our transmission… I wouldn’t run it.

LT3 is listed for E92 M3 6spd which uses MTF-LT2 as well. for some reason LT3 is not listed for E46M but i assumed it was good enough for that as well

I've heard mixed responses so I'll ask here.

Does opened gear oil, in this case MTF-LT-2 have a shelf life?

The cap has obviously been closed tightly but the seal has been broken. I used what I needed years ago and the remainder sat. I purchased a 5 liter jug at the time.

I wouldn't even consider using it but since this OE fluid is like $40/liter if I'm not mistaken, I rather not waste what I have.
