On my first tank of gas i got right at 26mpg in my "S". This was using the odometer and gallons to fill tank, not the computer which read a bit higher. I'm on my second tankfull and it appears that mileage will improve a bit. At what point did your mileage level off, and at what consistent rate of fuel consumption? I do a combination of highway/in-town. Thanks.

 

>> At what point did your mileage level off,

Shortly after break-in. About the 1500mi. mark.

I now get about 31-34 hwy and 22-25 in the city. I have a little over 12K miles on my MCS.

My MPG average is about the same as kesh420, with 15,000 miles on the odometer.
