Ah, another fellow Tampa Bay resident. OK, I'll be specific then.
Last tank I got 61 MPG according to the display, mostly driving from Spring Hill to Largo/Clearwater and back (stopping in New Port Richey on the way home much of the time) along US19 for my daily commute which is about 48 miles. When I attend church in New Port Richey, I do have short trips with a heated cabin, so my MPG drops.
We share the same weather, so I won't say much about that. My AC is set to 76 degrees.
Oil filled to 3.5 Quarts. Previous fills were a bit over the full mark. Probably lost a couple of miles per gallon because of this.
Tire pressure 40/38.
I frequently use Cruise Control, even on secondary roads. Often I drive more with the CC stick than the accelerator pedal.
I try to anticipate lights and coast as much as possible, but I am not anal about it. I probably could improve efficiency in this area by 50% if I really wanted to work at it.
During the summer, my MPG was closer to low to mid 50's. When I was visiting a friend in Tampa during June and July, I did more highway driving, so my mileage was closer to 52 for the whole tank, wich included my commute on US19. During the drive on the Suncoast, it was closer to 46 doing a legal 70MPH.
I took a trip to Tampa from Spring Hill last Saturday for a concert using the Suncoast/veterans, but limited my speed to 55. Mileage then was about 60.
