75W90 Gear Oil – Synthetic Protection for Transmissions & Differentials
When it comes to protecting your transmission and drivetrain, 75W90 Gear Oil is one of the most trusted synthetic lubricants in the automotive world. Designed for high-performance applications, this gear oil delivers consistent results in extreme temperatures and heavy-load conditions.
Whether you’re servicing your own car or managing a fleet of commercial vehicles, choosing the right lubricant helps reduce wear, increase efficiency, and prevent costly repairs.
What Makes 75W90 Gear Oil Stand Out?
Unlike conventional oils, 75W90 Gear Oil is fully synthetic, offering several key advantages:
- Wide temperature tolerance: Ensures smooth gear shifts in both freezing and hot environments
- Enhanced gear protection: Maintains film strength and reduces metal-to-metal contact
- Oxidation and shear resistance: Prevents breakdown over long drain intervals
- Seal compatibility: Works well with common gaskets and seals, minimizing leaks
Its superior formulation meets or exceeds API GL-5 and MT-1 requirements, making it suitable for high-performance and commercial applications alike.
Applications and Use Cases
You can use 75W90 in:
- Manual transmissions and transaxles
- Differentials (including limited-slip designs)
- Transfer cases and axle systems
- Passenger vehicles, trucks, SUVs, and off-road equipment
This makes it an ideal multi-purpose solution across industries—whether you’re in logistics, agriculture, or automotive repair.
When Should You Replace Gear Oil?
Routine checks are vital. Look for:
- Whining or grinding noises during gear shifts
- Delayed engagement or jerky movements
- Visible oil leaks from gear housings
- A burnt smell or darkened gear oil
Regular maintenance with synthetic gear oil extends component life and supports optimal vehicle performance.
