So I am going to give Motul a try.

I got 3qts of Motylgear 75W-90 and 1qt of Gear Competition FF Gearbox & LSD Oil - 75W-140

I opted for the Motylgear after some researching, next time thru I will try the Gear 300 oil. I am coming from Royal Purple Gear Max, I do have the cold 2nd gear notch with the Royal Purple. I will post my findings.

 

yea im getting my clutch put in tomm so im not sure what im gonna have them put in.. they have motul fluids at the shop im not sure if i want the blend or the ful syn

 

I have been using Motul 300 Gear in my RS 5-spd., and Competition ff in my TC and rear diff., for over 50K miles w/o any problems.

 

From what I've read, non-oem trany fluid is o.k. in the 5sp only. With the 6sp MR, I would suggest only using the oem Diaqueen fluids. I have a hunch that all the complaints about the 6sp trany being week and overheating/failing in 3rd gear are at least partially due to aftermarket fluids being used.

 

I went OEM Mitsu for all 3, from info learned on the board here, lots of knowledge. I run Amsoil in the engine, I like that product and would use their fluids for a 2nd choice. I don't drag and haven't modded my car, not yet anyway. Love the canyons though.

When I got the trans fluid for the 6 speed the parts guy said the part number is now the same for both 5 and 6 speed. Not sure if that's a recent change or not. I remember reading on this subject and thought the fluids did used to be different between the two. I'd think they used what they sell for the 6 speed in 5 speeds as well. From what I read in other threads quite a while back, it does work well in the 5 speeds.

 

For my evo 9 mr i use diaqueen for the tcase part #MZ313376

 

Old thread - I know.

On my 9 MR (all stock) I am using OEM Diaqueen. I find the 1-2 shift slightly notchy when cold. When warm, smooth as butter. Is that pretty normal, or a different fluid would be better?
