摘要

Engine manufacturers continually work to improve reliability, efficiency and value of the complex vehicles and engines they build and sell. Expectations for improved sustainability, environmental stewardship, conservation of resources and safety all result in the evolution of lubricants that help to enable an engine's ability to deliver on those goals. Lubricant development is largely tied to OEM and industry performance categories. In the passenger car segment, the most recent generation of lubricants was developed to adhere to API ILSAC GF-6 and OEM-specific categories, like GM's dexos1. Meanwhile, heavy-duty lubricants were developed to meet criteria set forth by API CK-4 and FA-4, the latter specifically categorizing low-viscosity formulations to help improve fuel economy in newer-model diesel engines.
