Purpose and Specifications

Castrol Syntrans V FE 75W-80 is a full synthetic manual transmission oil that delivers superior protection for your gearbox, synchronizers, and gears. Its 75W-80 viscosity flows smoothly at cold starts down to -40°C for easy shifting in winter, while staying strong up to 220°C to prevent wear during hot drives. API GL-4 rated with Audi TL 52532 approval, it's the go-to choice for 5- and 6-speed manual transmissions in Volkswagen, Audi, Seat, and Skoda vehicles, plus transaxles, transfer boxes, and final drives.

• Boosts fuel economy with low-friction formula that reduces drag without sacrificing protection.
• Extends synchronizer life for buttery-smooth gear changes over thousands of kilometers.
• Maintains cleanliness in high-heat conditions, keeping your transmission running like new.
• High shear stability holds up for the oil's full service life, typically 60,000-100,000 km or 3-5 years depending on driving conditions.

When to Use / Replace?

Use this oil in manual transmissions calling for API GL-4 specs, especially VW Group cars with demanding transaxles. Replace every 60,000 km or 36 months in normal driving, or sooner at 30,000 km in severe conditions like towing or extreme temps. Shelf life is 5 years when stored below 60°C away from sunlight.
