The tip about stopping less is actually really important, I feel. Before I go on a long trip, I deliberately deprive myself of drinks so that there won't be a need to stop halfway. The drive I frequently take is about 430 miles, mostly on interstate 95, and for my last trip this weekend, I got 66.2 mpg (according to the display - my tank isn't finished yet, but the mpg has plummeted in city driving). The biggest thing that helped was to go SLOW. 55 miles per hour was my setpoint, and I'd let my speed get lower than that (down to about 50) up a hill - of course on the back end of the hill I'd get 55 miles per hour back easily and then have a super high FE cruise at 55 miles per hour for a while. Cruise control on flat terrain does wonders, esp at slow speeds. You can lock in >70 mpg on a slow-speed cruise. If you can find someone else doing 55-60, for God's sake, stick with them. You don't necessarily have to draft on their bumper, but if it's a tractor-trailer or an SUV, you can get a noticeable FE benefit from just sticking behind them at a safe distance.


Although I'm becoming an increasingly big fan of the "draft RIGHT behind a trailer" school of thought. The FE benefits are just so hard to fight!
