[QUOTE="7.3powerstroke00, post: 484415, member: 48"] My 09 cclb 4x4 3.55s 35-12.50 tires and a 6 spd weighs in at 8400 lbs, at 70 turns just under 2000 rpm... Last weekend made a trip to Austin from brownwood and averaged 17 mpg mixed city and mostly hwy running the h&s hd300 with smoke control on 0.... If I turn smoke control up to 3 or 5 it drops mileage down to 14-15 mpg hwy and 10-12 city.... [/QUOTE]
