07 Yaris Hatch - Bad MPG?

I switched to Redline full synthetic a few years back and the car seems to be shifting better than it did from the factory. Been using DCFO and downshifting through my gears to every stop ever since I got the Yaris. I'm currently at 115k miles and haven't experienced any transmission issues yet (knock on wood).

How far apart do you think the mpg numbers would be? I know that mileage and maintenance is a big factor as well.

all on sticky 205s doing a flying 80. Im not sure who gets 40 mpg but .. wow

I feel anything better than 28 for what I do is great and if I can get 34 Id be mystified... that said

That's some really impressive numbers being a spirited driver, maybe you don't run into too many stop signs on your route. Might also help if the terrain was more leveled rather than including steep inclines and declines.

Also, I'm running the 15 inch steelies that the Yaris came with. It could be possible that people running after market rims could see better mpg due to weight savings in each rim. It requires less force to turn the wheels which makes a huge difference in city driving and stop and go traffic. On the freeway, I hear it's about the same with heavier wheels having the slight advantage of maintaining speed.
