Mileage and age cause the components of your vehicle's engine to wear. This allows oil to leak from the engine gaskets and burn from worn piston rings. Adding additives to your engine can reduce the amount of oil leaking from engine gaskets and the amount of oil blowing past worn rings and burning in the combustion chamber. It takes time for oil additives to circulate throughout the engine and reduce or stop oil leaks.

  1. 1

    Open the bonnet of your vehicle.

  2. 2

    Pull the dipstick from the dipstick tube. Wipe oil from the dipstick with a rag. Insert the clean dipstick back into the engine. Pull it out and look at the oil level.

  3. 3

    Read the directions on a bottle of oil additive. Remove the oil fill cap from the engine. Add oil to the engine if the dipstick shows the engine low on oil and the oil additive requires a full oil level.

  4. 4

    Pour the oil additive into the engine. Secure the oil fill cap to the engine.

  5. 5

    Close the vehicle bonnet. Start the engine. Allow the vehicle to run for 10 to 15 minutes to circulate the oil additive through the engine.

Tips and warnings

  • Drive your vehicle slowly for 250 miles to allow the oil additive to circulate through the engine.
  • Add a second bottle of oil additive to the engine if the oil leak does not stop after three days or 250 miles.
