65.1 mpg 90-day average
Well, I reached another big goal: a plus-65, ninety-day average (117% above "EPA"). The alternator mod, new non-fouled plugs, and higher-pressure tires are the probable reasons. Question: the 90 day calculation system seems to have changed. It seems now to be attached to the calendar. After both of my last fillups I was at one level in the 90 day average, only to see my number change a few days later as the calendar advanced. That's new, right?
