Mobil 1 Motorcycle Oils are advanced performance synthetic motorcycle oils. The unique, synthetic structure of the Mobil 1 Motorcycle formulations enables them to offer advantages well beyond conventional motorcycle oils of similar viscosities. For example, conventional mineral base oils change viscosity as the temperature changes.. This characteristic forces manufacturers of conventional, multigrade motorcycle oils to use additional additive thickeners which will help the oil maintain its viscosity as the temperature increases. These thickeners can shear down and lose their thickening capacity in an operating engine or transmission. Synthetic fluids, however, do not require much thickener to achieve a multigrade viscosity rating and, in some cases, do not require any thickener.  As a result synthetic formulations will provide a more shear stable and protective oil film for engine bearings, piston rings, transmission gears and other critical engine parts. than a conventional oil of a similar viscosity grade.

Both Mobil 1 Motorcycle formulations offer excellent flow characteristics at low temperatures to reduce engine wear at start-up, and outstanding resistance to oxidation and/or volatilization at high temperatures, both of which degrade the oil. Further, the Mobil 1 Motorcycle Oils provide outstanding protection against engine wear under high-temperature and high engine speed conditions. Each of the Mobil 1 Motorcycle product formulations have been optimized to meet the unique performance characteristics demanded by motorcycle engines and thus, provide a higher level of performance and protection for motorcycle engines than even the Mobil 1 Automotive engine oils.

Mobil 1 Racing 4T 10W-40 and Mobil 1 V-Twin 20W-50 4-cycle motorcycle oils

• Maximum shear stability to resist viscosity shear down in high performance engines and transmissions
• Exceptional thermal stability to resist oxidation and high-temperature degradation
• Outstanding protection against wear of engine and transmission components
• Enhanced lubrication to help maintain maximum power and acceleration over the life of the engine
• Optimized wet-clutch performance , meets JASO MA
• Excellent low temperature flow characteristics to help minimize engine wear during start-up

Mobil 1 Motorcycle Oils are full synthetic, high-performance engine oils formulated specifically to meet the demanding needs of motorcycle engines. Mobil 1 Racing 4T 10W-40 is designed primarily for on-road, high-performance, 4-cycle sport bikes, however, it may be used in other types of on and off-road 4-cycle motorcycles especially where a 10W-40 viscosity grade is specified. Mobil 1 V-Twin 20W-50 is formulated to offer outstanding protection in 4-cycle, V-Twin type engines, particularly those which are air cooled and tend to run hotter than other types of engines.

Mobil 1 Racing 4T 10W-40 and Mobil 1 V-Twin 20W-50 are recommended for 4-cycle, motorcycles which specify the use of a 10W-40 or a 20W-50 engine oil, respectively. These products will provide 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 Racing 4T 10W-40 and Mobil 1 V-Twin 20W-50 engine oils are also designed to provide the proper frictional characteristics necessary for wet-clutch engine/transmission systems. Mobil 1 Racing 4T 10W-40 and Mobil 1 V-Twin 20W-50 exceed the requirements of API Service Categories SJ, SH, SG/CF, CD and JASO MA . They have been fully tested, both on laboratory dynamometers and in the field, to provide optimum horsepower and acceleration.
