Purpose and Specifications

Shell Spirax S4 G 75W-90 1L is a semi-synthetic transmission oil designed for manual gearboxes in passenger cars and light-duty vehicles, especially Volkswagen Group models. It meets GL-4 and VW 501.50 specs, ensuring smooth gear shifts in cold starts down to -30°C and reliable lubrication up to 150°C operating temperatures.

This 75W-90 viscosity oil flows easily when cold for quick protection and stays thick under heat to reduce wear, cutting operating temperatures while boosting gear efficiency and fuel economy. Its advanced additives protect gears, bearings, and synchromesh for longer life, with potential to extend drain intervals up to 100,000 km or 4 years under normal driving.

When to Use / Replace?

Use in VW manual transmissions requiring TL 501.50, or any passenger car gearbox needing excellent synchromesh compatibility and high-temperature stability. Ideal for daily commuting, highway driving, or light towing where smooth shifting and durability matter.

• Replace every 60,000-100,000 km or 3-4 years, or sooner if you notice hard shifting, grinding noises, or burnt oil smell.
• Check fluid level monthly; top up if low.
• Shelf life is 5 years unopened when stored cool and dry.
