    Features & Benefits

    CD-2 Heavy Duty Engine Oil Stop Leak is designed for older vehicles that have developed minor leakage problems. Automobile engine bearing seals and gaskets shrink due to exposure to extreme environmental conditions or generally as the engine ages. This common problem usually results in minor oil leaks around valve cover gaskets, main bearing seals, rear seals or oil pan gaskets. CD-2 Heavy Duty Engine Oil Stop Leak reconditions the rubber components causing them to swell to their original size to close the sites where leakage has occurred.

    • Anti-wear and friction modifiers for maximum engine protection
    • Guaranteed to stop leaks
    • Added detergents keep oil cleaner longer
    • CD-2 Heavy Duty Engine Oil Stop Leak contains a blend of rubber conditioners and swell additives formulated into a motor oil compatible base
