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.
