i finally got to my 10,000 mile oil change last week, going to my usual place even though i had to bring my own oil, since they didn't carry it. both of the guys there commented on how neat they thought the car was, and how quiet it ran. when i mentioned the 55 mpg they really were impressed. they told me they will order the 0w20 and keep it in stock from now on.
i also had them bump the snow tires from 35 to 40 lbs. when ever i ask hubby, he says it's not good to run that high, so he won't do it. it made an immediate difference in the mileage. can't wait for spring, although the day i had the oil changed, it was so warm that the auto stop starting working again.....
