Manual Tranny & Rear Diff Oil... Suggestions?

[mikebike357]

I replaced my manual tranny oil and rear diff oil with Redline 70w90ns back in the spring and now that it's hot outside, I think it might be a bit too slick. Any suggestions in a synthetic that can handle the cold Maine winter as well as summer heat? Or should i just go back to dino???

I put motul in my diff and seems fine in the heat

Hey John,

Will that work in the STi's too?

I plan on swaping my gear oils out to synthetic.... motul is a wonderful oil!!!! It should work in the sti just fine, just make sure you get the weight oil for your car.

Sorry I didn't see this thread before. Yes Gear 300 is what I'd recommend in the STi's and WRX's.
