If cost (money savings) is your primary concern, maybe perfecting hypermiling driving style, and other things such as air dams, maxxed-out tire pressure, etc, etc. (unless you're already doing all of that, of course)
Now, if you're just dying to experiment with this dimpled surface idea for the sake of the experiment to see if you get results (believe me, I'm familiar with these types of obsessions, too), then I say "go for it" and let us know what happens.

The maintenance item I need to do is to have the injector nozzles replaced and set up properly. That's about 450 smackers and a weeks worth down time on the car! As far as tire pressure and hypermiling techniques I am already a student and in training
Have been using those techniques for a couple years now and still learn every day! The front air dam I may look into shortly along with flat covers for my wheels. Did you get a chance to see the Mythbusters dirty car vs clean car MPG(which also includes dimples in the experimentation)? They received quite a large difference in fact so much so that Jamie and Adam were speechless!
