    I know we've all been over avg MPGs and what not but I filled up the tank after my dentist appointment in Sherman and headed back to work in Durant. I filled up right by the highway and its a 30 mile drive back to work, which is right off the highway. So i reset all the trip meters and set to avg mpg. It surprised me given Oklahoma/Texas hills and me setting cruise at 75. I know its speeding, I don't care, look at the MPGs!!!

    It was up and down the whole way, saw a peak of 33.7 and a drop to 32.4 when it downshifted while going up a good grade hill, but this was when I got back off the highway 28miles later. Dropped to 32 flat once I pulled into the dealership and killed the car. Last 1/4 mile was thru 3 red-lights and stop and go noon traffic so its not so good in-town stop and go but we already knew this

    I got 43 on the way home once from college, hour drive home on the highway. I was surprised lol it was still slowly climbing so I wonder how much I could've gotten if I kept going.

    I get ~26 in the winter and 30 summer going about 70. I have a mpg tune for the warm weather is the suspected reason for the difference. When I had my stock wheels I got 32-33.

    i really don't like cruise control. i can feel when the computer cuts fuel, it gets really jerky.

    I drive I-95 multiple times a year, for just over 400miles. I set my cruise around 80, or try and tail someone doing a little more.

    I get around 31-38 depending on traffic/weather.

    Now if you tail a tractor-trailer doing 70mph, I've seen over 45mpg, which was tits awesome.
