Now they are back to dexos2. What did they learn?

Mobil 1 is not always dexos1. I was just in the oil aisle at Walmart the other night, and the blue dexos2 label was few and far between. All the Mobil 1 oil either had the green dexos1 label, or no dexos label at all. Valvoline 5W-40 MST full synthetic had the blue dexos2 label - this is one of the oils specified for Track usage in the 2018 owner's manual. The other dexos2 oil specified in the 2018 manual for Track usage is Mobil 1 ESP Formula M 5W-40 (hard to find in the U.S.). The Track recommendation (requirement?) is different than the daily driver recommendation/requirement.
But, as others have pointed out, each year seems to be different, even though the cars use the same engine. Very odd and confusing.
