The dexos specification is exclusive to General Motors, and any oil carrying the dexos logo is suitable for meeting GM warranty requirements. To meet the dexos requirements, an oil must typically be synthetic or a synthetic blend. GM stated that dexos was introduced to simplify oil selection and ensure increased fuel mileage. The American Petroleum Institute and the International Lubricant Standardization and Approval Committee have similar oil ratings.
Why am I coming across posts that Dexos is a product that makes up the oil.
How does "Dexos" protect timing chains. timing chains been around longer than Dexos rating.
when I look up Dexos it comes back as an oil approved by general motors.
