I drive a stock 2001 Trooper and get an average of about 16.5 mpg. I've been getting around 17 lately for some reason, maybe more hiway driving, although I push the 75 mph speed limit whenever I'm on good pavement <img src="/forums/images/graemlins/coolg.gif" alt="" />. Gotten as low as 12 hauling a trailer and never gotten better than 18 or so. Actually got worse by about 1-2 mpg when I put on a K&N cone filter for about 1000 miles, although the power was noticably improved. FWIW
