Purpose and Specifications

Comma SX75W90 GL5 1L is a semi-synthetic gear oil designed to protect modern five and six-speed gearboxes and differentials. It flows smoothly at cold starts down to -42°C, preventing hard shifting in winter, while staying thick under high heat and heavy loads for smooth, reliable performance.

This budget-friendly oil meets API GL-5 and GL-4 specs, making it ideal for hypoid gears and high-pressure applications. It reduces wear, fights rust, and handles extreme pressure without breaking down, giving you quieter operation and longer gear life.

When to Use / Replace?

• Use it in: Manual transmissions, rear differentials, and axles calling for 75W-90, 80W-90, or 85W-90 GL-5/GL-4 oils.
• Replace every 60,000-100,000 km or 3-5 years under normal driving; sooner (every 30,000 km) for towing, off-road, or heavy loads.
• Shelf life: 5 years from manufacture date (check bottle code YYYY.MM.DD). Store away from extreme heat or cold.

FAQ

Can I use this in my manual transmission? Yes, it's perfect for 5-6 speed manuals needing GL-5 protection, but confirm your owner's manual allows GL-5 over GL-4.

Is it safe for limited-slip differentials? It works in most setups, but check if your diff needs extra friction modifiers for quiet operation.

How much for a full gearbox change? Typically 1-3 liters depending on your vehicle; this 1L bottle is great for top-ups or smaller fills.
