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 is also an excellent choice of lubricant for aircooled Porsche engines where catalytic converter longevity is not a consideration. Please note that use of this product in an engine with a catalytic converter or particulate emissions filter may result in damage to these expensive emissions control devices.

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.
