Purpose and Specifications

Mobil Transmission Fluid 75W-90 is a synthetic blend transmission oil designed for manual and automated manual transmissions in commercial and heavy-duty vehicles. This 20-liter industrial container provides reliable lubrication for gear systems operating in demanding conditions.

The 75W-90 viscosity rating means the oil flows easily in cold weather (winter startup at -40°C) while maintaining protective thickness at high operating temperatures (up to 100°C+). This balanced performance prevents engine strain during cold starts and protects gears during intense highway driving or heavy loads.

• Excellent low-temperature fluidity for reliable cold-weather operation
• Superior thermal stability to resist breakdown under extreme heat
• Advanced anti-wear additives protect gears and bearings from friction damage
• Reduces noise and vibration for smoother gear engagement
• Extended drain intervals reduce maintenance costs and downtime

When to Use / Replace?

Replace transmission fluid every 60,000 to 100,000 kilometers or 2 to 3 years, whichever comes first. More frequent changes (every 40,000 km) are recommended for vehicles operating in severe conditions: heavy towing, mountainous terrain, extreme temperatures, or frequent stop-and-go traffic.

This product is ideal for commercial fleets, trucks, buses, and industrial equipment requiring robust transmission protection. The 20-liter container is suited for workshop bulk use or fleet maintenance programs.

Frequently Asked Questions

Q: Can I use this oil in my passenger car transmission?
A: This is formulated for commercial and heavy-duty transmissions. Check your vehicle's owner manual for the correct specification. Using the wrong fluid can damage your transmission.

Q: How long does this oil last once opened?
A: Unopened, this product has a shelf life of approximately 3 to 5 years when stored in a cool, dry place. Once opened, use within 6 months to prevent contamination and oxidation.

Q: What does 75W-90 mean in simple terms?
A: The '75W' means it flows like a 75-weight oil in winter cold, ensuring easy starts. The '90' means it maintains the thickness of a 90-weight oil at engine operating temperature, protecting gears under load.
