AMSOIL Upper Cylinder Lubricant 177 ml

The high heat of the combustion and the limits of the oil control piston ring lead to a lack of oil at the top of each cylinder. The unique additives of AMSOIL Upper Cylinder Lubricant 175 ml provide this lack of lubrication to combat the wear of piston rings and cylinders and maximize engine compression and performance. The lubricating capability enhancers also help protect fuel injection nozzles and other components of the fuel system from wear, ensuring excellent performance and long service life.
