Purpose and Specifications

RAVENOL Transmission Oil 1223202-020-01-999 is a reliable mineral-based SAE 90 gear oil designed for manual transmissions in classic vehicles, trucks, and off-highway equipment. It forms a tough lubricating film that cuts wear on gears and bearings, while fighting rust and corrosion for longer component life. This oil flows well from -17°C up, ensuring smooth shifting in cold starts, and holds strong at high operating temps up to 277°C to prevent breakdown under load.

Practical perks include excellent foam resistance to keep lubrication consistent during hard use, and oxidation stability for extended service - change every 50,000 km or 24 months in normal conditions. Shelf life is 5 years when stored cool and dry.

When to Use / Replace?

• Use in manual transmissions, transfer cases, and light industrial gears calling for API GL-1 or SAE 90 specs - perfect for older cars, motorcycles, and farm gear without hypoid demands.
• Replace if shifting gets noisy or gritty, every 50,000 km/24 months for daily drivers, or sooner (30,000 km/12 months) in heavy towing or dusty conditions.
• Ideal for temps from -17°C to 100°C+; drains easiest when hot for clean changes.

FAQ

Is RAVENOL SAE 90 safe for brass or bronze parts? Yes, it's non-corrosive to yellow metals like brass and bronze in transmissions.

Can I mix it with other gear oils? It's mixable but for peak performance, use it straight - no additives needed.

How often to check levels? Inspect monthly; top up if low, but full change every 50,000 km keeps it smooth.
