My best is 28.4 in last summer, cruising. Have hit 25s and 26s pretty often on long drives. Driving hard, but for more than 120 miles I get 23-25. Average daily commuting, 7 miles each way, drops me to 20, sometimes 19. Never had less than 19. Never expected to see anything above 24. After getting into 28s several times I decided I could drive this baby the way she was designed to be driven. Since I've never driven her to see the best I could get I wouldn't be surprised to get into 30 with a long distance econo drive. I'll report back if that ever happens.

Feel free to ignore my response...I didn't notice that it was an SRT6 post. My results don't factor into this thread. Apologies to all.
