Quality and performance considerations
The quality decision begins with the engine's required service category and viscosity. The card's designation does not establish suitability for every modern engine or exhaust-aftertreatment system.
Typical applications
Evaluate engines whose manuals specifically allow these requirements. Follow the manufacturer's service interval and verify current specifications before substituting this oil for a newer service category.
