i dont remember how much i paid for mine, i want to say 8 dollars a quart. plus no shipping charges

cool man, thanks, I'll def give a try. I'll keep posted when done.

[yamaha_rider619]

yup, that's what we're here for

[nofear6235]

This is an excellent question to pose to Redline themselves. I'd contact customer service before using it. I do not know if any component has fallen out of solution or if any component is not stable long term. Since it was sealed I don't think moisture is a concern, but I have no idea what's in the oil -- Redline do though. You might even email if you don't want to call. Just a thought.

I got reply from RedLine earlier today, it is also relevant to gear box oil.
When ask originally , I misnamed the type of oil under the question. That's why guy referring to GL-4. But actually I do have 75W90 Full synthetic which is GL-5.
Unfortunately I sent e-mail from work, so I can't post my exact original questions, but I receive CC answers to my personal account.

Anyways here answer # 1

Yes, it would still work (you need to shake it up first), but MT-90 is the wrong
gear oil for your Subaru. We don't suggest using products that old, as well.

You want our 75W90NS GL-5 for the transmission and our 75W90 GL-5 for the
differential. The MT-90 is not for that car. Subaru wants GL-5 in the trans, not
GL-4.

Hope that helps,

-------------------------------------------
Next I kept conversation with the guy, about other oil types
-----------------------------------------
Answer # 2

Your email said MT-90. Drunk, maybe.

I see in the photos, 75W90. Again, that's OLD stuff but should be okay if you shake it.

Answer #3

Sounds like you know, we don't recommend Shockproofs in the street cars. We know that Lightweight has worked for many in the 5-speed Subaru boxes, but be careful with the 6-speed STi box since it can get clogged.

We have to recommend what the factory wants but try to share the knowledge as much as possible.

I'm sticking with what Andrewtech recommends for the PPG gearbox... 1qt of Motul 300 and the rest LW Shockproof.

How long & many miles you already have on this mix as of now?
Did you try solely LW Shockproof? You probably mention this somewhere in the thread but I don't remember. Thanks Pavia.

10k on the last fill. I've used all shockproof before with good results, but the Motul 300 helps out in colder weather.

If I had a stock tranny, I would just stick with the Extra-S.

One of the dealer I pass show no interest to even talk about Extra S, forget about buying. I may try more places.
I always have more luck buying from people who looking to sell, than when I come to people and offer to buy.
So for me to get Motul 300 and LW Shockproof will be easy, online from dealers who looking to sell those products.
Would Motul/LW shockproof suits stock transmission, the same way as it does to yours modified tranny? Why you suggest Extra S over the mix you using now?

A lot of dealerships don't know about Extra S. At least not the service desk people.

It's their synthetic transmission oil.

I did ask the guy from parts dept, but yeah, I should've ask just for synthetic transmission oil, they may understand quicker.

You could use it for a stock tranny, but I wouldn't for two reasons. One, Motul 300 is pretty pricey and I haven't found an online source that carries both (so you pay more handling costs ordering from two suppliers). Two, it's best to go with 10k mileage intervals on the Shockproof, as it breaks down quicker. This means more services.

The dealer stuff (Extra S), Valvoline, or any of the other stuff listed in this thread maybe a better route for stock trannies.

[nofear6235]

Got today 4 qt of Extra S from local cooperative dealer along with Fuji liquid bond for rear differential plug. Tomorrow drain both, tranny and rear diff old oil and will update in awhile how much difference I see after using all mighty Extra S in my manual gear box

[blmfordj88]

I would just like to thank everyone for their time and effort in this thread. I spent days trying to figure out what to use and decided on the go extra s. It took away all notchyness in 4th and 5th and feels much better than when i bought it 2 months ago. Once again, THANKS a ton!

[nofear6235]

I should admit myself, I spent hours reading this thread and thanks for great write ups and answering all my question, I made correct decision.
Replaced my stock tranny oil with Extra S and for past 1,5 month feeling noticable difference in shifting.
When I have chance I'll post pictures I took that day, while working on oil swap, both tranny and rear differential.
Someone mentioned before that it's possible (after swap to Extra S) to put 1 gear before the full stop, and yes, it is.

:Edit on 10/10/2010: >> Some pictures..
last picture is for the rear differential stuff

[shadowpr]

Coming up on 30k miles, and going to change the tran/rear diff fluid.

Will probably go with the extra-s for the tranny. Does the rear diff take the same stuff, or something different? That's the one thing I'm still a bit confused about.

Thanks.

[Big Sky WRX]

you can put extra-s in the rear diff, but I wouldn't- too spendy, just get something along the lines Mobil 1 75W90- save the extra-s for the tranny where you will notice a difference
