What is your best mpg?

I just got 44.0mpg on 60mi trip!! I didn’t know that driving at the speed limits (65mph on freeway, 35mph on most city street) could get this much…. Previously it was 33mpg, so 11mpg more by just driving at the speed limits and a little attention to acceleration and braking. New respect to those elders who really drive slow…. 😂
