So, I added a Thule roof rack to my new (jan 09) CRV within weeks of buying it.
And quickly realized the wind noise would drive me crazy, so I dug up the Thule wind ferring I had from an older Thule rack I owned. And voila most of the noise was gone. But my gas mileage never went above 23, with a fair amount of highway driving. So this w/e, I removed it after I realized I can reinstall in about 20 minutes..now that I know what I am doing. And voila, my mileage for the first 100+ miles is now about 25.2 mpg, with no changes in
driving habit or type of traffic.
Is that decrease in mileage with a roof rack or maybe it was really the wind ferring, normal?
What do you think the most to the mpg reduction. The rack or the wind blocker.
