00014-42 - CASTROL Conventional Engine Oil GTX 20W50 , 1L (Pack of 12) - 0001442

This conventional 20W-50 motor oil is engineered for superior protection in a wide range of gasoline and diesel engines. Formulated to exceed API SL/CF and ACEA A3/B4 specifications, it provides robust defense against the sludge, deposits, and viscosity breakdown that can diminish engine life and performance. Its advanced formulation delivers exceptional thermal stability, ensuring consistent protection even under high-temperature operating conditions. This makes it an ideal choice for vehicles operating in warmer climates or those subjected to demanding driving situations. The 20W-50 viscosity grade offers a thick, protective oil film that is particularly beneficial for older, higher-mileage engines and classic cars that require higher levels of zinc (ZDDP) for wear protection on critical components like flat-tappet camshafts. By actively fighting against harmful sludge buildup and providing a resilient barrier against metal-to-metal contact, this oil helps to extend engine longevity and maintain optimal performance over the long term. It is suitable for use in vehicles where the manufacturer recommends an API SL, SJ, or CF lubricant.
