Summer mix give better fuel mileage?
I bought my first Insight last August, and it took a while to learn how to drive it to maximize fuel mileage. My worst tank was 63mpg, in December when it was cold, dark and wet. Starting in April, I seemed to steadily get better fuel mileage, from 72 to 75 and now to 80mpg on my average mileage ( I reset it each time I fill up). I drive in North Georgia, so I have to deal with plenty of hills.
Is the summer mix of gasoline that much better?
