Replying to: gregnw44 (Apr 27, 2009 10:41 pm) I had a 94 Legacy sedan with the 2.2 auto and got around 30. I sold it to my son when he got his license and I suspect he must get closer to the 20. There is a huge difference in our driving styles. I was taught to drive like there were eggs under the gas and brake pedals and was rewarded with great fuel economy. My son, unfortunately, is always in a hurry and accelerates and brakes hard. I coast. I have always recorded every fill-up in a small notebook and so, have a running tally of fuel economy - as well as a convenient place to record all maintenance. The columns in my record book are: date, odom, miles since last fill (delta odom), gals, $, mpg. I have recorded every fill-up since 1972 in this way.

Replying to: gregnw44 (Apr 28, 2009 1:42 pm) My guess is tire pressure and condition, plus alignment, are even bigger factors.   Not to mention driving style, and the previous post mentions.   My minivan has a trip computer and I can break 30mpg on highway trips if I drive smoothly and keep speeds down. We were driving to Florida and my brother got a turn behind the wheel while I slept, I think he was doing 90, and he got 25.somethign mpg.   Speeds make a big difference, also. Wind resistance increases with the square of speed, while rolling resistance only decreases linearly.
