I have been using Mobil 1 Extended Performance 5w-20 oil since I got the car in 2015 since it was Dexos -1 certified. I no longer see the Dexos-1 license on the bottles of this oil and Mobil 1's website no longer shows 5w-20 as certified Dexos-1 though 0w-20 and 5w-30 remain certified. Please note: GM dexos 1 Gen 3 engine oils exceed the performance of GM dexos 1 Gen 2 engine oils and are backward compatible, therefore vehicles that previously used GM dexos 1 or GM dexos 1 Gen 2 will use a GM dexos 1 Gen 3 or GM dexos R licensed engine oil of the appropriate viscosity grade at their next oil change. Yes, Mobil 1 high mileage 0w20 is Dexos approved. What Oil Brands are Dexos Approved? There are a few different oil brands that are Dexos approved, but the most popular ones are Castrol, Mobil 1, and Valvoline. These oils all meet the dexos1 specification, which is a GM specific oil standard. Applications Mobil 1™ 5W-30 is recommended by ExxonMobil for all types of modern gasoline-powered vehicles, including high-performance turbocharged, supercharged, multi-valve fuel injected engines found in passenger cars, SUVs, light vans and light trucks. General Motors recommends the use of dexos™ approved engine oils for global factory and service fill in spark ignited and diesel engines. Importantly, the number of brands with dexos approved licenses varies over time. The list of Licensed dexos® brands is updated quarterly, with the most recent update on December 16, 2020. Mobil Full Synthetic has met or exceeded Dexos 1 Gen3 in 5W-30 since the beginningit appears that Mobil Super Synthetic as well in both 5W-30 and 0W-20has GM recommended or required Gen3 Dexos one Gen2 in anything yet???
