Purpose and Specifications

MOTUL Gear 300 LS 75W-90 is a fully synthetic, ester-based transmission oil designed for high-performance and racing vehicles. It delivers superior anti-wear protection, smooth gear shifting with less effort on the lever, and stays reliable under extreme shock loads in gearboxes, differentials, and limited-slip systems.

This 20-liter container suits mechanical transmissions in track cars, rally vehicles, and even electric vehicle drivetrains, meeting API GL-5 standards for extreme pressure performance. It flows easily in cold starts down to -40°C and maintains thickness up to 150°C, ensuring consistent protection during intense driving.

• Smooth shifting: Reduces gear lever effort for quicker, precise changes
• Longer gear life: Extreme pressure formula fights wear, extending component life by up to 50% in racing conditions
• High-temp stability: Resists breakdown in hot operating environments over 120°C

When to Use / Replace?

Use this oil in synchronized or non-synchronized gearboxes, transfer cases, and hypoid differentials with limited-slip under high shock. Ideal for performance cars running track days, rallies, or heavy off-road abuse where standard oils fail.

Replace every 30,000-50,000 km or 24 months in racing use, or at manufacturer intervals for street/high-performance driving. Shelf life is 5 years unopened when stored cool and dry.

FAQ

Q: Is this oil suitable for my daily driver?
A: Yes, but it's optimized for high-performance; check your manual for 75W-90 GL-5 compatibility to avoid warranty issues.

Q: How does it handle cold weather?
A: The 75W rating ensures smooth shifting in temps as low as -40°C, perfect for winter starts without grinding.

Q: Can it be mixed with other gear oils?
A: Best to fully drain and replace for maximum protection; mixing dilutes its ester-based benefits.
