What elevation are you at? For whatever reason, I got the best mileage at an average of 4000ft when in eastern Oregon. It's not quite as good here on the Oregon coast.31-34MPG in Colorado with 85 octane. I have a 2106 Rene Latitude Manual 1.4L and drive 70-30 Highway to City. I have found that if you shift before 3000 rpm and maximize cruise control and keep the speed less than 72mph, I can reliably get 36mpg on the highway.
