Asked by Tracy B. In Alabama

How much Sea Foam should I add to the crankcase oil and how long or how many miles should I drive it before changing the motor oil?

Thanks for the questions Tracy. You can add 1 to 1.5 ounces of Sea Foam for each quart of motor oil your crankcase holds. Most car and light truck crankcases are 5 or 6 quarts, so eyeballing half a can is a decent rule of thumb. We recommend adding to the oil crankcase 100 to 300 odometer miles before each oil and filter change.
