What do motor oil additives do?
Auto parts stores are jam-packed with aftermarket motor oil additives and oil treatments that promise a great number of advantages and benefits. These claims include:
Increased fuel economy
Improved engine cleanliness
To provide this additional performance, aftermarket motor oil additives use chemical components to boost the motor oil formula. Some aftermarket motor oil additive products have added ingredients like Teflon, molybdenum or graphite. Some have used chlorine, which can be highly corrosive when mixed with water.
