Purpose and Specifications

RAVENOL SLS 75W-140 4L is a fully synthetic transmission oil designed for manual transmissions, rear axles, and differentials, especially those with limited slip (LS) features in high-performance vehicles like Jaguar, BMW, and Mercedes-Benz. This 4-liter canister delivers a tough lubricating film that holds up under extreme heat up to 150°C and heavy loads, preventing wear on hypoid gears and reducing noise even when hot.

It flows smoothly in cold starts down to -40°C for easy shifting, protects against rust and oxidation for longer life, and meets API GL-5 LS and MIL-L-2105 D standards. Perfect for motorsport, track days, towing, or daily driving in demanding conditions, it cuts gear whine and extends component life up to 100,000 km or 5 years with proper use.

When to Use / Replace?

• Use it when: Your vehicle has a limited slip differential, manual gearbox, or hypoid axle under high stress like racing, towing heavy loads, or off-road; check your owner's manual for 75W-140 GL-5 LS spec.
• Replace every: 60,000-100,000 km or 3-5 years, or sooner if you notice grinding noises, hard shifting, or burnt smell - inspect fluid level and color during oil changes.
• Storage: Keep sealed in a cool, dry place for a shelf life of 5 years.
