I was recommended this oil for my 2004 WRX 5mt rear diff. Turns out it's for LSD clutch style STI differentials. NOT WRX!! So here I am running to find rear diff oil, while I'm halfway through a fluid swap. I informed the representative of the vehicles year, make, model, and transmission. And now I'm stuck with something I can't use, and a dry diff.

First off thanks to RSD for always having the dopest products! This stuff simply a must have if you have an 06' STI. Little of a pain to get it in the diff without making a mess but Motul fluids all the way!

Did a change about 3k ago. Did not have any grinds or weird noises before. Still going well after about 3,000 miles. Easy to do with a cheap hand pump from the parts store.
Great Diff Fluid

Had a bit of diff chatter. Replaced fluid that was in there from previous owner with a quart of Motul 90PA and it's way better. Good stuff, and one of the few approved for the '04 STi rear diff.
QUESTIONS & ANSWERS
Q: LSD Differentials jaymie98 11 months agoAnswer
RSD, I have 2007 Subaru Forester XT with a JDM Forester STI 6 speed which has 2 Suretrac LSD,s (front & rear). I purchased the Motul 90pa for both diff & gearbox but the gearbox seems to have a slight wine & vibration over 70mph, any recommedations?
A: It could be that the oil that you put in your transmission has a high viscosity which might give you a slight whine. However it could also be your clutch parts. I would start by diagnosing any clutch issues and if the clutch is all good go with a different trans oil.

Q: 2009 sti dubaru 3 years agoAnswer
Will there be any gains or positives to using this over the standard motul 300 in my rear diff? If not then Ill just purchase the motul 300. Secondly, what should I use for my front diff? I see everyone talking about tranny and rear diff but not front diff.
A: This fluid is for clutch-pack or plate type differentials. In 07+ STi's that use a torsen you can simply use the standard Motul 300. The 90PA can be used, but its not needed as your Torsen LSD does not require a special fluid like a clutch type unit that the 04-06 STi have. This is not recommended for the Transmission(which houses the front and center diff) on the STi due to the friction modifier that is added, The Motul Gear 300 is a better option for the 6MT Transmission.

Q: JDM 04 Sti Ejzok 4 years agoAnswer
What's the different between PA90 and 300 (both non-LS and LS)??? Im so confus I run trackday twice a month, so please recommend which one should I be using for Gear and Rear Diff, thanks!
A: The PA90 is more useful for clutch type unit that comes in this 04-06 models where as the 300 is a more generic gear oil. You could use either without any issues.
