This fuel grade thread got me thinking. I am higher altitude so we have 85 octane as our regular here. Since the manual calls for 87, I've always just used the mid-grade 87 octane, plus you never know when you might be going to a lower elevation.
When I had that loaner 2019 GT, I was struck at just how freaking sluggish to accelerate the damn thing was compared to my 2014 CX-5. Figuring they are putting 85 octane in it, think that could be one of the reasons?
The 85 should act like 87 up here, but I just don't know enough about that stuff and have just always stuck with what the manual said to use.
