Our 2007 hits regular and has no noticeable pong. Even under heavy acceleration. 2019 I much prefer blending e85 and regular at an e30 final blend. Should be 2 parts regular and 1 part e85. It will yield roughly 93 octane for LESS than regular and zero fuel economy loss. If no e85 available we run mid-grade.
GM 6.2 Premium Fuel?
