Dexos is a GM-developed engine oil specification that has been designed to:
· Further improve fuel economy (to meet future Corporate Average Fuel Economy, CAFE, requirements) and fuel economy retention, which allows the oil to maintain its fuel economy benefits throughout the life of the oil
· Provide a more robust formulation for added engine protection and aeration performance
· Support GM's Engine Oil Life System (EOLS) and minimize use of engine oil
· Ensure worldwide availability of high quality oil for factory and service fill needs
· Reduce the duplication of requirements for a large number of internal GM engine oil specifications
TIP: The oil specified in prior model years remains acceptable for previous models; however, dexos1 is backward compatible for older veh
