That premium fuel only would be a deal killer for me. Have to really need that extra HP for towing to make that worthwhile unless money is just not important. Does seem like the 2021s and newer use more gas than the previous models.
Has always killed the deal for me. Most any desirable vehicle has to have premium, and they are charging + .80 over regular in my area. Gangsters.... Diesel is +.30 over RUL and I go 40% further on it.....

The whole premium fuel thing…i think its kinda a joke myself. Put 125k on last denali with 6.2, never had nothing but regular in it, ran great, great fuel mileage. The ‘22 high country with 6.2 has 40k, never had nothing but regular, runs great. Maybe long term motor issues? I dono.
