Amsoil 100% Synthetic 4T Performance Motorcycle Engine Oil is formulated to lubricate four-stroke motorcycle engines, integrated gearboxes and wet clutch systems that share a common oil supply. This Special Offer includes 5 x 946ml (1 U.S Quart) bottles, giving you a useful quantity for full oil changes, routine top-ups and planned servicing across multiple maintenance intervals.Review the key features of this motorcycle engine oil:100% Synthetic Base Oil Technology: Premium synthetic base oils are engineered with uniform molecular structure for stable lubrication, strong film retention and dependable flow across a broad temperature range, helping reduce start-up wear and maintain protection once the engine reaches full operating temperature, which supports smoother running and consistent reliability. High-Temperature Thermal Stability: The formulation is designed to resist oxidation, viscosity breakdown and heat-related thickening during sustained high engine temperatures, air-cooled operation and slow-moving traffic conditions, helping the oil remain effective for longer and supporting dependable lubrication when heat levels rise. Shear-Stable Viscosity Protection: Motorcycle gearboxes place heavy mechanical stress on engine oil, so shear-stable viscosity improvers help the oil retain its intended grade under repeated gear loading, which supports ongoing bearing protection, smoother gear engagement and stable performance between service intervals. Wet Clutch Compatible Friction Control: The oil is blended without friction modifiers that can interfere with clutch plate grip, helping maintain clean clutch engagement, controlled pull-away and steady power transfer through the drivetrain, which gives you predictable operation in town riding and on longer runs.Advanced Anti-Wear Additive System: High-pressure anti-wear chemistry helps protect cams, followers, gears, bearings and other heavily loaded internal parts from metal-to-metal contact, reducing component wear during repeated acceleration, deceleration and stop-start use, which helps preserve engine condition over time. Detergency and Deposit Resistance: Cleaning additives help suspend contaminants and reduce sludge, varnish and carbon build-up around rings, valve areas and oil passages, helping internal components stay cleaner and allowing oil to circulate properly, which supports efficient running and easier maintenance.Low Volatility Formula: Heat-resistant synthetic content helps reduce evaporation loss at high temperature, lowering oil consumption and helping maintain the correct oil level for longer periods, which means fewer checks and more consistent protection between changes.You get stable lubrication, clutch compatibility and gearbox protection from one oil developed specifically for motorcycles that place several demands on a single lubricant. The 5-bottle pack gives you practical workshop stock for scheduled servicing, seasonal maintenance and keeping spare oil ready when levels need attention. Keeping this set in your garage is a smart addition to your motorcycle setup when dependable running and straightforward maintenance matter.
