STP 4-Cylinder Oil Treatment helps protect against engine wear by increasing oil viscosity, which provides a thicker cushion of oil between moving engine parts and reduces metal-to-metal friction. It counteracts oil thinning and also contains additives to boost motor oil's anti-wear protection. This product is optimized for 4-cylinder engines. Use every oil change.
