Engine Shield® is the ultimate protection for the moving metal parts in your engine. Utilizing the most advanced and non-corrosive boundary film technology, it protects moving metal parts from wear and damage due to boundary conditions of frictional abrasion, extreme pressure torquing, dry startup and engine shutdown. Other benefits include increased fuel savings due to reduced friction and increased oil flow, reduced maintenance and downtime, extended engine parts longevity and reduced operating temperatures. Other benefits include increased fuel savings due to reduced friction and increased oil flow, reduced maintenance and downtime, extended engine parts life and reduced operating temperatures an average of 30 to 50 Fahrenheit degrees.
