my cats went down to Costco 93 unleaded at 80K miles. I bought into all gas is the same arguments. Very expensive repair.
I only ever used Mobil one and then Castrol Edge both with little ZDDP. Then I switched to Motul Xcess and let the intervals run longer...now out of the blue I have sticky lifter giving me a fairly quiet but slightly wobbly idle (less than 1 hash mark). Moral of the story.... buy expensive oil and change it twice a year if you drive year round. Keep that oil fresh.
