The industry benchmark in lubrication technology. Designed for those who demand the absolute best in motor oil performance. The exclusive “extended drain” formulation delivers superior engine protection and maximum fuel economy and exceeds the requirements of modern, high performance and older engines.

Drain interval of up to 35,000 miles/1 year

Engineered to outperform all conventional gasoline engine motor oils. Reduces heat, friction, and wear for maximum performance and fuel efficiency. Clean engine formula resists high-temp breakdown that forms sludge and varnish. Lasts longer and offers better protection.

Drain interval of up to 25,000 miles/1 year

Formulated for the needs of European gasoline cars and light trucks. Blended with a broad 5W-40 viscosity rating. Allows for the maximum extended drain intervals recommended while providing superior protection and performance.

Recommended for the extended drain intervals established by the vehicle manufacturer or extend based on oil analysis. Change oil filter at time of oil change.

For use in both gasoline and diesel engines. Offers multi-functionality and wear protection. Ideal for applications where the extra protection of a higher-viscosity oil is desired. Excellent for motor homes and older vehicles, as well as many types of modern equipment and compatible with some motorcycles.
