Welcome to the site Oryoki! Congrats on your purchase and I'm glad to hear you like your F
Your going to fit in great here, feel free to ask any questions you might have 
I drive my IS-F daily as well. My overall in-town average has been around 19 mpg, which isn't bad for 416 hpWelcome Scott. As a daily driver, what do you think of the fuel economy?
I think that's one of the most surprising things about this ride. I've averaged nearly 23mpg since getting it. I don't do that hypermiling nonsense either.Welcome Scott. As a daily driver, what do you think of the fuel economy?
I know what you mean. I also like the double-hit when you punch it. The first hit wakes up your kidneys; the second hit throws them in the back seat.If I'm not heavy on the foot and keep my highway speed under 80 I've averaged as much as 26-28mpg on a tank.

Amazing! I drive most of my miles in town and my overall avg is 18.4mpg. I normally don't see anything on tank avg much higher than 23 and that only lasts a short time...must be heavy on the foot. I just love to hear the ROAR, I'm addicted to it.
