Mustache only made it through one tank before it got "lost"...
However on the other side of it...got my best ever from Houston to Ardmore...26.98mpg! This run is usually around 21-23mpg.
So now I have this crazy idea fer an adjustable air dam. Something that I can pivot down fer highway speeds but allow it to bump up when it comes to obstacles. I might use another noodle fer the test material but eventually move on to something longer and durable.
