You're still in break-in. Give the car another 2k-3k miles to see a jump in the mileage.

I am at 28mpg with 70-80% hwy. I have found that it drops if using cruise control and dips at and above 80 mph.

I've observed Sunoco premium gives me a better mpg over other brands of gasoline, with 75% hwy 25% city driving in my 2006 IS250 AWD.
Sunoco 91 - 28.4
Exxon/Shell 93 - 27.7
BP 93 - 26+
