Purpose and Specifications

MOTUL MOTYLGEAR 75W-80 is a full synthetic transmission oil engineered for manual gearboxes that demand smooth shifting and reliable protection. This 20-liter container provides professional-grade lubrication for vehicles with synchronized or non-synchronized transmissions, differentials, and transfer cases.

Key Performance Benefits:

• Reduces friction and wear in gearbox components, extending transmission life
• Lower viscosity at cold temperatures allows easier gear shifting when the engine is cold—less effort on the gear lever
• Maintains proper thickness at operating temperatures (around 100°C / 212°F), reducing drag and improving fuel efficiency
• Extreme pressure additives protect against shock loads and heavy-duty operation
• Compatible with all seal types and yellow metal synchronizers used in modern gearboxes
• Resists foaming and corrosion for stable long-term performance

Specifications: API GL-4 and GL-5 rated | SAE 75W-80 viscosity | 100% synthetic Technosynthese base stock | MIL-L 2105 D compliant

When to Use and Replace

Recommended For: Peugeot, Citroën, Renault, and other European vehicles with manual transmissions, especially those with notchy or hard-to-shift gearboxes. Suitable for all mechanical transmissions operating under normal to heavy loads.

Replacement Schedule: Follow your vehicle manufacturer's maintenance schedule. Most manual transmissions require a fluid change every 80,000–160,000 km (50,000–100,000 miles) or every 3–5 years, whichever comes first. Check your owner's manual for exact intervals.

Operating Temperature Range: Performs reliably from approximately -30°C (-22°F) at startup to 100°C (212°F) under normal driving conditions.

Storage: Store in a cool, dry place. Unopened containers maintain quality for several years when kept away from direct sunlight and extreme temperatures.

Frequently Asked Questions

Q: Will this oil work in my synchronized manual transmission?
A: Yes. MOTUL MOTYLGEAR 75W-80 is explicitly designed for synchronized gearboxes and is safe for yellow metal synchronizers. It reduces gear grinding and provides quieter, smoother shifts.

Q: How much fuel economy improvement can I expect?
A: The 80-grade viscosity at operating temperature reduces gearbox drag. Drivers report measurable improvements in fuel consumption, though the exact benefit depends on driving habits and vehicle condition.

Q: Is this oil suitable for limited-slip differentials?
A: No. MOTUL MOTYLGEAR 75W-80 is designed for transmissions and differentials without limited-slip systems. Check your vehicle's specifications before use.
