I get between 38 and 42 mpg on my daily interstate commutes, I get closer to 38 mpg if Im driving 70+ and 42 if I drive like 63 mpg in cruise. here in Kentucky I-75. Keep the RPM below 3,000 and the car does really well. I like to run at a speed of 2800-2850 on the interstate in my AT.
good to see an automatic transmission still going strong at 157,000 miles.
