Do I need to add MotorSilk™ again after an oil change?
MotorSilk™ is not a common oil additive which attempts to enhance or improve the performance of the oil. Oil additive products must be used often because they are inert leaving no lasting or residual effect. Rather, MotorSilk™ forms covalent solid boundary lubrication bond to metal alloy. Treat engine every 100,000 miles.
