309.4 ÷ 8.615 = 35.91 mpg
Ugh. At least I know why the mileage was so bad this time. I’ve realized over the course of the past 9 months that this little car is horrible on gas mileage when it idles. After a doctor appointment last week in the city, I sat in traffic for at least twenty minutes to move approximately three tenths of a mile to the exit!
