Valvoline Oil Treatment contains a polymer that increases the viscosity index of engine oil, making the oil more viscous (thicker) at high temperatures without increasing viscosity proportionally at low-temperatures.

Oil Treatment also contains an extreme-pressure additive that helps reduce engine wear.

>> Minimizes oil consumption
>> Reduces friction
>> Improves piston ring seal and compression
>> Increases lubricity
>> Improves viscosity index of oil
>> Protects engines from extreme-pressure wear
