Living in sunny Alberta (it got above 0 F today... makes it a nice, mild,
January day), I put remote starts in jst about everything parked in my
driveway.... I refuse to figure out my fuel mileage....
Besides, if fuel consumption really meant that much to me, I'd be driving
some dipshit little econo box....
FWIW, aside from making sure we have no driveability concerns (in the
original posters case, a code scan and/or a "Quick Test" may be in order -
even, perhaps, having the fuel trims read), and that we aren't the victim of
neglected serviceing and/or filter changes, our driving conditions and
habits can do more to ruin fuel mileage numbers than most realize.
