Help... Which differential fluid??

SilverSlug · 12-04-2020, 08:54 PM

So I'm at 92k miles and I would like to flush all the fluids to assure they are fresh.

Which differential fluid do I need to use for my 2011 E93 6MT??

ECS Tuning shows two different ones which are both genuine BMW??

https://www.ecstuning.com/b-genuine-...j/83222357992/

https://www.ecstuning.com/b-genuine-...r/83222282583/

Are these the same thing in different bottle types??

And then there is also this kit, which has even a different looking bottle, but also includes the drain and fill bolts.

Which one of these three should I get?

After reading around on here I ordered castrol syntrax 75w-140 LS, €18/0.5L instead of €45 with the dealer. Haven't done the job yet but from what I read it seems to contain just about enough FM.

Just replaced mine last week. My shop, which primarily focuses on e92/90 M3s, used Castrol syntrax

Right. All three of the links I posted from ECS Tuning are 75-140 LS, but the bottles look different on each, and are differently priced.

Do you know what's up with that?

This is the correct fluid for your car. The other link you posted with the grey bottles with green tops will work also. They were just superseded by the new clear bottles with red tops. Same fluid., BMW just decided to save some cash and get rid of the extended fill neck.

Ah okay, got it.

Do I need new fill/drain bolts every time I flush?

I'm at 92k miles... Not sure if/how many times it's been done before.

The plugs have o-rings. You don’t need new plugs but I don’t think you can buy the orings separately so you are stuck with buying both. Maybe someone has a source for orings. I think it’s reasonable to buy new plugs and orings after ~10 years and 92k miles, but if I was changing the fluid every 30k miles, I would not buy them.

Like pbonsalb said. It wouldn't hurt to replace your drain/fill plugs with new ones since you're at high miles.

i myself just bought the Castrol kit since most people on the forum had no issues with it.(i did see one person with issues with chatter

: ). There is someone selling oem fluid in the for sale section if that's what you want.

No extra noise on my diff.

Interesting. Is it quieter than OEM Genuine BMW fluid from your experience??

I wouldn't say quieter, but I haven't noticed any changes in noise compared to what I had in there originally.

Chatter = diff clutch hock up. You don't want it to be too silent.

I recently used Royal Purple. No issues.
