13.6 MPG all city driving!

Well i was worried about going to make my first fill when i noticed i was on a 1/4 tank with 197 miles on the trip OD. but turns out i filled it only 14.4 gallons so I guess my last quarter actually holds 8 gallons! I am going to take her on her fist road trip tommorrow to College Station, about a 3 hour drive. Already gve her a top off of oil, she was just serviced before i bought her so i think i will chane her this weekend. Oh and my engine is stock, no mods, and it was done about 80% normal and 20% sport mode.

Here's a project for you. PLEASE drive one way in regular mode and the other in powermode, fill up on both ends and tell us what the fuel mileage difference is. try to drive the same style both directions, there is a gas light that comes on with about a gallon of usable gas left if you want to risk it.
