Purpose and Specifications

RAVENOL MTF-1 75W85 is a fully synthetic transmission oil built for tough manual transmissions, transfer cases, and differentials. It handles extreme heat up to 120°C and cold down to -40°C without thickening or breaking down, keeping shifts smooth and gears protected during heavy towing or off-road use.

This PAO-based fluid meets API GL-4 and GL-5 standards, plus approvals like MB 235.4, Fiat 9.55550-MZ1, and GM specs, making it ideal for Mercedes, Fiat, GM, and similar vehicles. In a 10L canister, it's perfect for complete flushes on larger systems.

• Stays fluid in freezing winters for easy cold starts and precise shifting
• Resists foaming and corrosion to extend gear life under high loads
• Supports extended drain intervals up to 100,000 km or 5 years in normal driving
• Reduces fuel use with low drag and smooth operation

When to Use / Replace?

Use RAVENOL MTF-1 75W85 in manual gearboxes calling for 75W85 GL-4/GL-5 fluid, especially under severe conditions like frequent towing or high-mileage driving. Replace every 60,000-100,000 km or every 3-5 years, or sooner if you notice hard shifting, grinding noises, or slipping gears.

Shelf life is 5 years unopened when stored cool and dry. Always check your owner's manual or VIN with a mechanic to confirm fit.
