2021 Mazda6 Turbo Carbon Edition Fuel Efficiency

I have the 2021 Mazda6 Turbo Carbon Edition. Has anyone used anything other than hi-test fuel and if so, did you notice a difference in performance or fuel efficiency? Thanks

Sounds like an opportunity for you to do some research and report back to the group.
I was actually thinking the same thing as well. I have such an uncanny thirst for knowledge. I am still at 1/2 a tank of premium so I'll let it get abut a 1/4 of a tank, use low grade and see if there is much of a difference. i will definitely get back to the group this one. :)
You may be better off doing 2 or 3 tanks of each in a row running it below 1/4 tank to insure you have a clean test.
