Purpose and Specifications

RAVENOL MZG 80W-90 GL-4 is a premium mineral-based transmission oil designed for manual transmissions, differentials, and steering gears in vehicles needing robust EP protection. Its 80W-90 viscosity flows smoothly in cold starts down to -33°C while staying thick under high heat up to 242°C flash point, ensuring smooth shifts and long gear life even under heavy loads like towing or off-road driving.

This oil meets top specs including API GL-4, ZF TE-ML 02B/16A/17A/19A, MB 235.1/235.14, MAN 341 E1/Z1, and Ford SQM-2C 9008-A, making it perfect for European trucks, older Mercedes, ZF transmissions, and classic cars.

• Builds a tough lubricant film to prevent gear wear during high-load conditions
• Excellent cold flow for easy shifting in winter down to -33°C
• Superior rust protection for metal parts and seals
• High thermal stability resists breakdown in hot operating temps
• Low foam even at high speeds for consistent performance

When to Use / Replace?

Use RAVENOL MZG 80W-90 in manual gearboxes, axles, and steering systems per your vehicle manual. Ideal for heavy-duty use like commercial vehicles or classics running in extreme temps from -30°C to +150°C operating range.

Replace every 60,000-100,000 km or 3-5 years under normal driving; sooner (30,000-50,000 km) for severe conditions like towing, frequent stop-go, or dusty roads. Shelf life is 5 years unopened when stored cool and dry.
