Well i replaced the spark plugs last weekend and I've gone through about 1/2 a tank so far and its looking great. Before that plugs i calculated it at 25MPG :( and now the in car is saying 35 MPG! But i will still be doing more of what people suggested and i will calculate it by hand and post back later to tell you the results.

Going to put in a new fuel filter, oil change, and clean the MAF next.

P.S. the air filter on my model is a lifetime airfilter... WTF. cannot be changed... who designed this crap.
