Mobil 1 Racing™ 4T Motorcycle Oil

Experience performance for four-cycle motorcycles

Mobil 1 Racing™ 4T 10W-40 motorcycle oil is designed primarily for on-road, high-performance, four-cycle sport bikes. It also may be used in other types of on- and off-road four-cycle motorcycles that specify the use of 10W-40 engine oil.

The unique, synthetic structure of the Mobil 1™ motorcycle oil formulations offers advantages beyond conventional motorcycle oils of similar viscosities.

Mobil 1 Racing 4T has been fully tested, both on laboratory dynamometers and in the field, to help provide optimum horsepower and acceleration.

This full synthetic motorcycle oil helps provide excellent performance in motorcycle engines that are either:
  • Designed with a common engine/transmission lubrication system, or
  • Designed so that the engine lubrication system is separate from the transmission system. (Follow the manufacturer's recommendation for the type of fluid to be used in the transmission.)

Please reference our Mobil 1™ Product Guide for a quick look at specifications including zinc and phosphorus, as well as manufacturer approvals for Mobil 1 motor oils.

Features and benefits

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