Subaru Extra-S 75W-90 High Performance Gear Lube

Extra-S gear oil is what Subaru uses on all its high-performance models.  According to Subaru, this fluid has the following benefits:

• High film strength minimizes wear and protects gears
• Extreme pressure additives provide additional protection for high load conditions
• High Viscosity Index for use in a wide range of temperatures
• Anti-rust and corrosion inhibiting additives enhance the ability to combat corrosion resulting from water and acids
• Anti-foam package to minimize foaming and disperse foam in the oil
• Superior oxidation resistance to ensure performance in severe operating conditions

One quart bottle.

Nomenclature note: Subaru used to sell a drivetrain fluid called "Extra S" that came only in five gallon pails. The five-gallon pails were discontinued and Subaru started offering this one-liter bottle instead. Subaru of America tells us this is the exact same fluid as the old Extra-S, which is why we advertise it with the Extra-S title.
