With the running to & from the football field these days, it won't take long to burn that gas! Although, I had some Series 40s installed and my instant mpg jumped 2 spots. Still makes no sense to me how I can increase hp, yet increase mpg at the same time. I'm now getting 16-18 on the expressway. Used to get 14-16.

As for the premium fuel, I'll listen to the experts. Being new to this area, I don't have a relationship with a dealer yet, therefore no one to give me some special consideration should something happen.
