Funny you should phrase it that way When I drive I drive normally but take some care to not ride the gas pedal and the brakes. I get around 47 mpg, at least during the warmer spring and summer weather (winter is another issue here in Manitoba) When my wife drives, she gets around 40-41 mpg which comes, I believe mostly from riding the gas pedal until the last possible moment when she has to brake, if not hard, then at least moderately hard. I've tried to educate her and change her habits to no avail (and have now chosen to give up rather than risk 28 years of marriage). Point is, even with her "bad" habits and even in our colder climates, over 40 mpg is easily achievable. Even my worst tank in the depths of winter with lots of idling with the heat running have yielded better than 33 mpg. And yes, sometimes I use ethanol blended gas too. Gotta be something up with the car.
