Well, that was the first thing I put into my new car. I am happy to report it has gone up from 1.5 mpg to 1.95 mpg. I'm really thinking if I just put it in neutral going down hill I can achieve the vaunted 2.0 mpg.
All jokes aside though, first fill-up on the car I put Aces in. I believe in it and am happy with the results from RS6 and 335 so I'm hoping it will work just as good in this car.
