Torco V-Series "ST" v-twin oil

Torco V-Series ST Motor Oil is a unique petroleum based motor oil specifically designed for late model Harley Davidson and custom v-twin engines. It is formulated using highly stable hydrocracked base stocks and our race proven MPZ additive providing better cooling, cleaning, ring sealing, deposit control and wear protection. Special additive and polymer components maintain viscosity in high temperature environments found in air-cooled v-twin engines.

V-series ST 20w50 v-twin oil is recommended for use in late model air cooled or liquid cooled engines commonly found in Harley Davidson (Big Twin - Evolution & Twin Cam 88 engines) and many other v-twin applications.
