AMSOIL Synthetic Motor Oils are formulated for both water-cooled and air-cooled engines. Conventional petroleum oils break down and oxidize when faced with high temperatures, such as those experienced when pushing your equipment to the limit, contributing
to the formation of deposits, sludge and varnish. AMSOIL withstands oil breakdown and oxidation in high temperatures, holds contaminants in suspension and keeps engines running cool and clean.
Zinc and phosphorous additives are extremely important to engines faced with high-pressure conditions, especially motorcycle-type engines, which typically have steep cam slopes, creating high pressure between the parts.
