    • 340,000 Miles and Counting
Size: 1 Pack Color: 16 oz
Started using Seafoam about a year ago when my 2016 Toyota Camry was burning oil. I was using about a quart of oil every 1200 miles. I started putting 5 oz in the crankcase and the remainder of the bottle in the gas tank 200 miles before every 5000 mile oil change. After two treatments, the oil consumption rate is about a quart every 6000 plus miles. Reduced engine noise and improved performance. The Camry is going on 340,000 miles with all original parts. It works for me. ... show more

    • Like Oil Detergent
Size: 1 Pack Color: 16 oz
Added to my oil, as directed at 1oz/qt, to clean up sticky variable valve timing solenoid oil control valve issues in my 23 year old Pathfinder. Still running great with mostly all original engine control parts. Just needed a bit of internal engine cleaning needed to remove years of residue from those small oil passages. Saved me the cost of replacing the VVT solenoids. ... show more

    • Seafoam procedure before oil change
Size: 1 Pack Color: 16 oz
I add 1.5 ounces per liter of engine block. For example I drive a 4.0 liter V6 engine so i add 6 ounces in my engine oil crankcase. And drive 100 miles than drain oil. And conduct my regular oil change procedure.
