Subaru Extra-S Tranny Gear Oil

[RyanR]

First impressions: Shifts like buttah, even in the cold!!! Shorty/Adam hooked me up with some @ Evergreen and I could not be happier. Upshifts/Downshifts are MUCH improved. It is exactly what I was looking for in a gear oil.

I'll update when I've put a bunch of miles on it.

Subaru part #: K0322AA093 It's a 75w-90 so you can toss it in almost anything.

I know this isn't turbo powertrain specific, but we don't have a tranny forum!

Sweet. I'm hopin' this stuff will quiet my RS down.

werd. I can't say that I paid any attention to tranny noise before/after so I can't speak to that. However, I did pay attention to everything else and couldn't be happier haha.

You'll have to bring your own container to EG as it only comes in bulk.

[GClark]

How much would a quart be?

I do not like the Subaru Extra-S. Never had much luck with it in my tranny box.

I'm using Scotty's cocktail right now.

works well for mine

and it's cheap enough that it's worth a shot. maybe extra-s is not so awesome for the bugeye trannys? I've seen scotty's cocktail work well in them, but haven't had any experience with it in a 6spd and don't really like the whole "cocktail" methodology unless the tranny already has issues.

Big fan of extra-s. Had it in my RS and now my WRX. Both trannies liked it.

 

[Nicklaus220]

What do you guys think of Royal Purple Transmission Fluid?

I have a Bugeye looking to do a flush soon

 

[2point5RS_Dan]

It's fine. Get whatever 75w-90 you want. It's not like a different or certain brand will cause your junk to explode.

 

[MikeD]

Dan's right. I just used Mobil 1 75w90 in both differentials/gearbox and its nice and smooth in acceleration and shifting. However, if I had known I could by the amount I needed at Evergreen, I would have gone there instead of advance auto.

 

[Nicklaus220]

Thank you Dan & Mike.

How much did enough extra-S to fill your tranny and diff run you at EG?
