Thicker oil film at operating temperature than a petroleum 10W40

Specifically blended for air-cooled V-Twin engines with traditionally wide clearances like Knuckleheads, Shovelheads and Panheads engines

Extended drain intervals over other brands due to higher quality base stocks and excellent dispersants

Designed for the latest Big-Twin motorcycle engines that specify 20W50 motor oil, including Milwaukee-Eight, Evolution, Twin Cam and aftermarket engines of similar design

Popular for 65cc, 85cc, 125cc and 250cc two stroke motocross transmissions, as well as shifter kart gearboxes and CRF transmission cases
