I got my scan gauge, did a partial grill block, and drove by the scangauge increasing speed slowly, staying under 65 mph most of the time, coasting some ,drafting some, after 2 tanks thru my 2002 echo sedan using the gauge. i am dissaponted by my results. only 1-2 mpg more, i was hoping to get up where some of you guys are, i went from 44mpg to 46 one tank and 45 the next,, and i get 42-44 driving with no thoughts for milage. my commute is 105 miles a day to work and back 70% 45mph zone 20% 55-65 mph zone, 10% 25-35 mph slight traffic ,about 10 traffic lights. What am i not getting here,(i tried hard to keep the mpg up high on the scangauge),how do i get over 50 mpg? or can i in this toyota echo 5 speed, no ac no power steering.
