How are you doing it at 90 degrees and no A/C? You have the windows down and find that comfy?

I’ve heard the drag at highway speed with windows down causes more mpg loss due to drag than running the A/C at highway speeds.

Have you tested that?

Edit: *NVM I just saw you said 3mpg loss for A/C lol
