Purpose and Specifications

Castrol 75W Syntrans FE 1L is a full synthetic manual transmission oil designed for smooth gear shifts and long-lasting protection in passenger cars with conventional manual or dry clutch transmissions. It meets API GL-4 standards and is approved for Ford WSS-M2C200-D2 (like Focus, Mondeo, Transit) and Mercedes-Benz approvals, ensuring it flows easily at cold starts down to -40°C for quick protection and stays stable up to 226°C to keep gears clean.

• Smooth shifting: Excellent friction properties extend synchronizer life for effortless gear changes, even in daily traffic.
• Fuel savings: Low-viscosity formula reduces drag for better mileage without sacrificing wear protection.
• Cold weather ready: Pumps fast at low temps to prevent startup damage and improve shift quality.
• High heat endurance: Maintains thickness in hot conditions, preventing sludge buildup for transmission life up to 150,000 km.
• 1L bottle perfect for precise refills or complete drains.

When to Use / Replace?

Use this oil in Ford, Volvo (C30, S60, XC70), and compatible manual transmissions calling for 75W API GL-4 fluid. Replace every 60,000-100,000 km or 3-5 years, or sooner if shifting feels notchy, noises appear, or during high-heat towing. Shelf life is 5 years unopened in cool, dry storage.

Pro tip: Check your owner manual for exact specs - this oil shines in temps from -40°C to over 100°C operating range.
