Why Use An “Upper Cylinder” Lubricant?

Oil-control piston rings can limit the amount of oil making it to the very top of the cylinder. Also add in the extreme heat generated by today’s engines. This product is delivered to this region by way of the fuel. This extra measure protects against wear in the upper cylinder area.

Stops Ethanol-Related Corrosion

Most all regular-grade fuel contains ethanol. Ethanol attracts moisture and this can create corrosion inside your engine. AMSOIL Upper Cylinder Lubricant contains powerful anti-corrosion ingredients that protect engine parts against internal rust and corrosion.

Maintains Clean Fuel Injectors And Combustion Chambers

Regular use of AMSOIL Upper Cylinder Lubricant prevents fuel injector and combustion chamber deposits. This maintains performance and optimizes fuel mileage. For a complete fuel system cleaning, we recommend the periodic use of AMSOIL Performance Improver.
