Purpose and Specifications

RAVENOL Transmission Oil 1222101-B20-01-888 is a fully synthetic SAE 75W-90 gear oil designed to protect manual transmissions, differentials, and axles in cars, trucks, and heavy-duty vehicles. It flows smoothly at cold starts down to -40°C for quick protection and stays thick under extreme heat up to 150°C, reducing wear and extending gear life by up to 50% compared to conventional oils.

This premium fluid cuts operating temperatures, quiets noisy gears, and boosts fuel efficiency with superior friction reduction. Ideal for high-torque conditions like towing or off-road use, it meets API GL-5 standards for reliable performance in limited-slip differentials without extra additives.

When to Use / Replace?

• Use it in: Manual transmissions, rear/front differentials, and transfer cases specifying SAE 75W-90 GL-5 oil. Perfect for European, Asian, and American vehicles under severe service.
• Replace every 60,000 km or 3 years under normal driving; every 30,000 km or 18 months for towing, racing, or extreme temps to prevent sludge buildup and maintain smooth shifts.
• Shelf life: 5 years unopened when stored cool and dry.
