Cusco Transmission OIL 75W-85 FF-MR-4WD Front 1L Mineral NON-SYNTHETIC Fits Subaru STI Evo
Cusco Transmission Oil 75W-85 FF-MR-4WD Front 1L is a mineral non-synthetic gear lubricant designed for front differentials in FF MR and 4WD vehicles. It delivers reliable protection for limited-slip differentials in high-performance cars like Subaru WRX STI and Mitsubishi Lancer Evolution. This oil maintains viscosity under extreme loads for smooth gear shifts and reduced wear during track or street use.
Key Features
- 75W-85 Viscosity: Ensures smooth flow at startup and stable protection at high temperatures for consistent performance in demanding conditions.
- Mineral Non-Synthetic Formula: Provides cost-effective durability with excellent film strength for everyday and motorsport applications.
- LSD Optimized Additives: Includes extreme pressure agents and friction modifiers to prevent judder and chatter in front limited-slip differentials.
- 1L Bottle Size: Matches exact fill capacity for front diffs in popular JDM 4WD vehicles simplifying fluid changes.
- High Shear Stability: Resists breakdown under heavy loads keeping gears and bearings protected longer than standard oils.
Product Notes

- Store in cool dry place to maintain oil integrity before use.
- Ships in protective carton to prevent leaks during transit.
