Subaru Extra S Gear oil......anyone use this locally?
#7
I'm using Extra S seems to work well in all conditions. Cold mornings, hot afternoons. Shift feel seems to stay consistent.
I've tried Redline, smooth when warmed up but a bit stiff and notchy when cold.
Motul, had similar issues as well a bit less tho since I added a little friction modifier to help the syncros.

Yes you can they are both 90w oils, but the STi's will want to use the LSD oil since it has friction modifiers to help the clutch type diff. The wrx and other models with the viscous rear diff doesn't matter because the LSD units in those are sealed.
