But with the latest tank, I got 27.6 MPG! Which is the highest I experienced in this car.

On a regular day, the breakdown is probably...
With city driving, I get about 18-20 mpg.
Hwy & city, I get 20-22 mpg.
Out of town RX7 meet or out of town trip, I get 22-25 mpg.

But the latest tank I did, out of town trip, and hwy & city driving.
Averaging 70 mph on the hwy.
And got 27.6 mpg.

Someday...30mpg...someday.

I call BS, brother.. i bet the gas pump was not calibrated right. the best ive seen is 24.5 which was mostly crusing at 60mph, i usually get 16 mpg city. rtek 2.1
