First Road Trip of the Year in the S4

The family just finished our first road trip of the year with the S4. About 600 miles round trip from Monroe, WA to the small town of Pilot Rock, OR. I averaged 30.1 MPG, but I'm sure it would have been better if I was driving the speed limit. It was a packed car with 3 adults and one kid, and still the ride was very good with the Solo-Werks coilovers.  

I ran a can of BG 44k fuel system cleaner in the first tank just to keep everything in good shape. I normally run a fuel system treatment once every 6 months when I go on a long drive. EPL recommend this so I figured I give it a try. Honestly, I can't really tell any difference, but it's just preventative maintenance.  My wife 2003 Toyota Highlander is having a high idle issue so I'm going to try a can in that car and see if it helps. 

Anyway... all is good and looking forward to the Leavenworth Drive on June 15th!
