10.8 mpg in my 6.0 liter.. What the heck??!!!?!?
i have an 03 CC lariat 4wd psd with 55k on it. its lifted 6in with 35" toyo's. only mod is a 4"tb exhaust with kitty and muffler(came like that when i bought it). i'm lucky if i can get 300 miles out of a tank of diesel. i don't drive it hard, i haven't towed anything with it yet, what is going on? i've heard of some people with bigger lifts than me getting 18mpg+!!!
how do i do this?? if i could get 15mpg i would be stoked!
cut off kitty and muffler?
i'm still under ford esp extended warranty too.
driving down to AZ next month, towing a small trailer, would like to improve my situation before then.
any help is much appreciated!!
