Does mileage get better with age?

Does anyone remember how to reset your ECU after the break in period is done?

tranquility, the car learns based on your driving habits and slightly alters its performance based on those characteristics. Not saying it will make a big dent in your gas mileage but it's a good idea to reset the ECU once you feel comfortable so it doesn't remember how you had to drive during your break in period.
