I tried searching and cant really find much on it but I was thinking about doing a mix of 2qts redline MT90 and 1qt of BG syncromesh. I heard the BG doesnt really have the protection that the redline has and I figured this would help my trans shift better but still have good protection.

I heard you're not supposed to mix, but I can't back that up with anything

Im gonna be changing my synchromesh (same stuff) with every oil change

I ran synchromesh alone for 60K without any problems. Barely any shavings after each change at 10K -- still shifts like butter. Keep in mind I drive this car like a grandma. Don't know how it would hold up if you're banging gears a lot.

I have tried BG synchromesh, personally my tranny didnt care for it.

Fwiw these are some of the fluids I have tested in my evo:

GM synchromesh
BG synchromesh
MT90 redline
redline cocktail 1 mt90, 2 mtl ( iirc the usual mix used on here)
amsoil gl-4
oem diaqueen
redline lightweight shockproof


each of these had been in the car long enough to have tested them out for a few track and autox events. Hands down winner has to be the redline cocktail mix, amsoil was really nice as well. MT90 was really notchy when cold, when it warmed up was fine, lightweight shockproof seemed to be the opposite for me. was fine cold but didnt care for how it acted on my tranny when it was hot. synchromesh and diaqueen are on the bottom of my list. I wouldnt use that stuff ever again in my car, imo. For whatever reason I was getting really notchy shifting when cold, gear lockout issues, and nasty decel noises frequently that I had thought was my trans going out.

These are my opinions, take it for what its worth, ymmv.

Yea I tried the amsoil and the factory fluid but I have the redline cocktail in it now. I was thinking about maybe adding a little BG to help the syncros as I get the occasional grind when shifting hard into 4th.
