I know my auto gets 27-29 on highway with the roof rails off. With the rails on it got 25-27 max MAYBE 28 if I drove 65mph. I commute 22miles each way so the 1 -1.5mpg gain was worth it. And I like the no rail look. I was shocked it actually helped...

Both of them get 25 city and around 30 highway. I get about 20-21 in town and only jump to about 24 on the highway. I know the 5 speed wagons are geared differently, so I'm wondering if that makes the difference. Can anyone elaborate on their experiences?
