When its running... I run it HARD, so the answer to your question is yes. BUT in my DD focus I have been learning to drive it without giving it any more than 1/4 throttle (I drive like an old lady) but in doing so my average miles per tank has gone from 290-300 to 350+ PER TANK!!! And its only like a ~12 gallon tank too. I don't think that is too bad concidering it is an auto.
I have to do it at least once everytime I drive it. But lately I have been trying to be good and not get on it too much. So usually once in the morning on the way to work and once on the way home. The rest of the time I putt it around to save gas. Already knocked down 230 miles on this tank and its barely at a quarter.
well the car is my dd now since the honda has a rod knocking. Ill prolly start driving it next week till it blows. Yes the cobra most every time im out in it get full throttle atleast once if not more.
not every time im out since its a daily driver... but my commute to and from school has two road options...both of which are long, straight, pretty clear of traffic and i love the sound of my exhaust... you get the idea
