Marvel Mystery Oil MM14R 1 Gallon

Unlike some products that simply burn up and billow out your car's tailpipe, Marvel Mystery Oil offers long lasting protection to your car's hard-working engine by cleaning and adding a lubricating layer unparalleled by the other fuel and motor treatments. Adding Marvel Mystery Oil to your gas tank restores engine performance, improves gasoline mileage, extends spark plug life and prevents gum build-up. It also cleans and lubricates fuel injectors and carburetors. Added to oil, it prevents valve sticking and clatter, fortifies properties of engine oil, prevents breakdown caused by extreme temperatures, reduces and prevents acid and sludge formation and promotes easier freezing weather starts.
