Hit 28.31mpg on the trip from Wichita to Ardmore with the cruise set to 65mph. It's usually around 23-25mpg.

Even maintained over 25.5mpg from Ardmore to Houston...with some speeds up to 100mph. I usually see under 25mpg at 65mph.

Nothing fell off or got ripped off at those speeds.

So I was thinking...the rear wheel skirts rubbed on the inside exposing the ribs. Wouldn't some of the air pressure being generated escape through those ribs and out the back side of the rear wheel skirts via the ribbed channels? Any data to suggest that using a channeled extractor setup would help?
