Purpose and Specifications

RAVENOL TGO 75W-90 is a semi-synthetic transmission oil engineered for maximum-duty manual transmissions, differentials, and hypoid geared axles. This 4-liter container delivers professional-grade protection for vehicles that demand reliable gear lubrication under heavy loads.

The oil flows smoothly at cold temperatures (down to -45°C) while maintaining protective thickness at high operating temperatures, ensuring consistent performance year-round. It meets strict industry standards including API GL-5, MIL-L-2105D, and approvals from major manufacturers like Mercedes-Benz, ZF, Ford, and Mack.

Key Benefits

• Extreme Pressure Protection: Specialized additives shield gears from wear during heavy acceleration, towing, and sustained high-load driving
• Rust and Corrosion Defense: Protects internal metal surfaces from moisture and oxidation damage
• Fuel Economy: Reduced friction in the drivetrain helps improve overall vehicle efficiency
• Extended Drain Intervals: Excellent oxidation stability allows longer service life between oil changes
• Cold Weather Performance: Pours easily in freezing conditions while maintaining protective film at operating temperature

When to Use / Replace?

Use RAVENOL TGO 75W-90 in manual transmissions, rear differentials, and transfer cases where your vehicle manufacturer specifies API GL-5 fluid. Check your owner's manual for the exact capacity and drain interval—most manual transmissions require fluid changes every 80,000 to 160,000 kilometers or every 3 to 5 years, whichever comes first. If you tow regularly, drive in mountainous terrain, or experience frequent heavy acceleration, consider changing the fluid at the shorter interval for maximum protection.

This oil is suitable for year-round use in climates ranging from -40°C to +100°C operating conditions.

Frequently Asked Questions

Q: Can I mix this oil with my current transmission fluid?
A: No. Always drain the old fluid completely before adding RAVENOL TGO 75W-90. Mixing different oil types can reduce protection and cause shifting problems.

Q: How do I know if my transmission needs new fluid?
A: Dark, burnt-smelling fluid or difficulty shifting gears are warning signs. Check the dipstick or sight glass monthly—the level should be between minimum and maximum marks when the vehicle is level and cold.

Q: Is this oil safe for limited-slip differentials?
A: RAVENOL TGO 75W-90 is formulated for standard hypoid gears. For limited-slip differentials, use RAVENOL LS 75W-90 instead, which includes friction modifiers for proper clutch operation.
