| Two tanks for my S auto I just filled up for the second time. OBC says 29.4mpg average. I got it with 18 miles and the average was 28. Been going up steadily.
My running mileage goes between about 12 and 99.9 (max?) It spends most of its time between 28 and 45. Can this be averaged over a little longer so the numbers do not bounce around quite so much?
My old Cooper started at 26 mpg for my first gallon and averaged almost 30.5 for the first 100K until they switched the the winter blend last fall when it reverted back to about 27. |
