I was driving back from a trip that was 400 miles. I drove most the way 10-15 above the speed limit. And i was getting about 40mpg for the trip. As i was coming back, i filled up in Indiana before hitting Illinois high gas prices and decided to see what the best MPG i could get on this car. I basically watched the meter on AVG MPG to try and keep it near 60. Well, i was pretty impressed at what i came up with, I was going between 60-63 the whole time in a 55 zone and it was 99% highway and in sport mode.
