Purpose and Specifications

CASTROL 15D917 is a premium synthetic transmission fluid in a convenient 1-liter bottle, engineered for smooth shifting and long-lasting protection in dual-clutch transmissions (DCT). It meets strict standards like VW TL 52529 and is recommended for VW G 052 182, Chrysler Europe, Ford WSS-M2C936-A, Mitsubishi SSTF-1, Peugeot Getrag DCT, PSA oil 9734 52, Skoda 6-speed DSG, and Volvo DCT.

This fluid delivers practical benefits: superior heat resistance up to 120°C for heavy traffic or towing, easy cold starts down to -40°C, and reduced wear for gears that last 100,000+ km. It keeps clutches clean, prevents sludge buildup, and ensures precise shifts without jerking.

When to Use / Replace?

• Use it if your vehicle has a 6-speed DSG or compatible DCT system from VW, Skoda, Seat, Peugeot, or listed brands – check your owner's manual.
• Replace every 60,000 km or 4 years for city/highway driving; sooner at 40,000 km if towing or in extreme heat/cold.
• Shelf life: 5 years unopened in cool, dry storage.
