I've only logged three all-highway tanks with it (none including track days), so not exactly a lot of miles logged...
Before the richer retune for 10% ethanol fuel, I actually had a couple of 27mpg tanks and one at 29mpg that were not logged!
But anyway, at 24.9mpg average, mine is the highest-mpg RX-7 on Fuelly.com
http://www.fuelly.com/car/mazda/rx-7/1994/Behemoth/307346Not bad for a ~200mph-capable car...
(there is another one showing 30mpg average, but it's mostly sub-20mpg entries with a couple of 60+ mpg entries thrown in. Something is amiss there...)
