This thread caught my eye.. I have a '98 3.8 V6, auto, and the only real mods are Flowmaster duals and BBK intake. I got exactly 30 mpg one time, and it was a highway trip. I gassed up right next to the highway, then 250 miles later as soon as I pulled off the highway I gassed up again, and it was 30 mpg. This was in summer, so it was about 90 degrees outside, and I had the A/C going the whole time. My gears are Ford stock; I think 3.27??
