Re: fuel mileage change??
Well, great minds think alike. I just filled up with my second tank and thought to try this for a tank and compare.
1st tank = 20.7 mpg with a mix of city / hwy.
This will be an interesting experiment and in a couple more tanks the 1K mile "break-in" period of the engine will be over and any restraint towards getting decent gas mileage will go out the window in a "whoosh" of SC howl!
Did I mention "I love this car!!"?
