Castrol Act Evo Semi-Synthetic 4T Engine Oil is a 20W-50 motorcycle lubricant formulated for 4-stroke engines that require dependable protection during everyday riding. This partially synthetic oil combines conventional and synthetic base oils to help manage operating temperatures, support smooth shifting, and protect critical engine components under a range of riding conditions. The 1 U.S. quart bottle is suitable for maintenance applications where a 20W-50 motorcycle oil is specified.
Castrol Act Evo uses TriZone Technology to provide protection for the engine, wet clutch, and gearbox with one specialized lubricant. Its formulation helps reduce friction and wear while promoting consistent clutch engagement and gear changes. The oil remains active after the engine is turned off, helping protect internal components between rides and supporting longer intervals between oil changes when permitted by the motorcycle manufacturer.
Designed for compatible 4-stroke motorcycles, Castrol Act Evo 20W-50 should be used according to the vehicle owner’s manual and applicable service requirements. Verify viscosity and performance specifications before installation to ensure proper fitment for your motorcycle.
