Purpose and Specifications

Castrol 15EEFE is a premium synthetic hydraulic oil in SAE 75W grade, perfect for high-performance dual-clutch transmissions (DCT) and hydraulic systems in vehicles from PSA, Nissan, BMW, VW, Ford, and Mercedes-Benz. This 4-liter bottle delivers smooth power shifts, protects against wear in extreme conditions, and keeps your transmission running cool and clean.

Key benefits include outstanding thermal stability for reliable operation from -40°C to 120°C, excellent water separation to prevent sludge buildup, and superior anti-wear protection that extends component life by up to 50% compared to standard fluids. Its high viscosity index ensures easy cold starts and stays thick under high heat, reducing downtime and maintenance costs.

• Approved for PSA 9734 S2, Nissan DCT fluid, BMW MTF LT-5 & DCTF-2, VW G 052 182/A2 & G 055 529, Ford M2C218-A1/M2C936-A, MB 236.21/22/24, and more
• Shelf life: 5 years unopened in cool, dry storage
• Prolongs fluid life up to 60,000 km or 3 years with regular checks

When to Use / Replace?

Use Castrol 15EEFE in modern DCT and hydraulic systems demanding precise shifting and protection under heavy loads or varying temperatures. Ideal for performance cars, trucks, and machinery where stock fluid fails prematurely.

Replace every 40,000-60,000 km or 2-3 years, or sooner if you notice rough shifts, slipping, or overheating. Check fluid level and condition monthly; dark color or burnt smell signals immediate change to avoid costly repairs.
