I didnt think 69 degrees would make a difference but it seems the more I drive the car the better it gets. The car is handling a little better and the engine sounds better and best of all the fuel economy is getting better. I got 400 miles to a tank where as I was getting about 330. Its still not as economical as the mazda and never will be but its not too shabby.
