differentiated solutions for motorcycle engine oils

OEMs are designing modern motorcycle engines to be more compact and efficient, with increased power density and tighter tolerances between moving parts. This puts additional pressure on motorcycle oils to meet more complex performance demands. A standard passenger car motor oil (PCMO) is no longer ideal for maintaining a motorcycle in good operating condition, as demonstrated in the chart below. The two types of vehicles require a different lubrication solution. Modern motorcycle engine oils (MCO) must not only protect moving parts within the engine but also clutches, the gearbox, and after-treatment systems. 

Chevron Oronite is recognized as one of the technical and market additive leaders for two-stroke and four-stroke motorcyle engine oils. We maintain strong relationships with original equipment manufacturers (OEMs) through continued and advanced technical support. We are proactively engaged in the industry to watch for emerging trends and to be prepared for future specifications in motorcycle engine oils.

Marine outboard engines require maximum reliability from lubricant products. Our 2-stroke (2T) and 4-stroke (4T) water-cooled additive packages have been the industry reference for performance and are supported by the Boating Industry Association and the National Marine Manufacturers Association (NMMA). We also develop products for direct fuel injection (DFI) in 2T engines and lubricants meeting the NMMA FCW-WTM certification for 4T engines. 


Chevron Oronite's water-cooled additive packages offer reduced ring groove deposits, robust rust and corrosion control, and anti-scuff protection.
