Friction is caused by electrostatic bonding forces that cause mechanical parts and abrasive contaminates in motor oil to be attracted to each other. No-Mor-friction reverses this relationship from bonding to repelling . When you change your oil a large amount of wear oil particles stay attracted to your engine and do not come out. No-Mor-Friction charges the particles the same as the engine so they drain out completely. Call me to gain more understanding.
