Motul 90 PA Limited Slip Differential Oil 2.1QT
Motul's 90 PA was specifically designed for vehicles with LSD(limited slip differentials)due to its very high lubricating characteristics. It can be used with hypoid differentials or vehicles without LSD. This gear oil was made to withstand heavy load and high shock conditions. It is seal safe and has a friction modifier for clutch pack/plate type differentials to keep the discs from dragging. This can be used on a variety of vehicles and is ideal for racing, street vehicles, and even construction vehicles!
Note: 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.
