Mobil 1 V-Twin 20W-50 is recommended for four-cycle motorcycles that specify the use of a 20W-50 engine oil. It provides excellent performance in motorcycle engines that are designed with a common engine/transmission lubrication system or where the engine lubrication system is separate from the transmission system. In the case of the latter, follow the manufacturer's recommendation for the type of fluid to be used in the transmission. Mobil 1 V-Twin 20W-50 engine oil is also designed to provide the proper frictional characteristics necessary for wet-clutch engine/transmission systems. Mobil 1 V-Twin 20W-50 exceeds the requirements of API Service Categories SH, SG/CF, CD and has been fully tested, both on laboratory dynamometers and in the field, to provide optimum horsepower and acceleration. Fully synthetic Mobil 1 motorcycle oils are specifically engineered for use in motorcycles. The formulations are based on the proven technology used in other Mobil 1 automotive products, yet they are optimized for the unique requirements of a motorcycle engine and/or transmission. You can use them with confidence, knowing they will protect your bike in extreme situations where conventional motor oils simply can not stand up, including extended high-speed operation and prolonged idling in summertime traffic. Like Mobil 1 automotive products, the three Mobil 1 motorcycle oils are based on proven, advanced synthetic oil technology. These unique, fully synthetic motorcycle oils are scientifically engineered to withstand the extreme heat produced by high-revving motorcycle engines and the toughest riding conditions. These formulations are designed specifically for the unique needs of motorcycles.
