Are you talking about diff fluid? If so go OE. It's crazy expensive, about $150 or so, but definitely the best option.Last edited by heinzboehmer; 04-08-2020, 09:52 AM.2002 Topasblau M3 - Coupe - 6MT - Karbonius CSL Airbox - MSS54HP Conversion - Kassel MAP - SSV1 - HJS - PCS Tune - Beisan - MK60 Swap - ZCP Rack - Nogaros - AutoSolutions - 996 Brembos - Slon - CMP - VinceBar - Koni - Eibach - BlueBus - Journal

Another vote for OE.
Only expensive once with FCP.

Yeah definitely get it from FCP so you can make use of that lifetime warranty later on.
This is the fluid, you'll need three bottles.

I used Liquimoly's diff oil for 5k miles with no issues. It came with friction modifier already at where it needed to be. I'll probably be switching to Motul for my next service.This is my Unbuild Journal and why we need an oil thread

Now i'm with Motul 75w140 FF Competition in all my cars and works great. Probably no difference or at least not noticeable compare to OEM (castrol) or Castrol anyways.Comment

It probably holds up on the track better. Doubt in daily driving though. Motul is pretty much the pinnacle of regular oil. Then you start getting into stuff like the Joe Gibbs stuff. I think they may do diff oilOriginally posted by bjz! View PostThis is my Unbuild Journal and why we need an oil thread

Well thanks everyone for the input
this morning I ordered OEM oil from FCP Euro about 20 bucks more for the three bottles then it would be from ECS but I guess if I keep her long enough it will pay off thanks everyone2004 M3 Mystic BlueComment
