Second best "fuel" mileage today:
Was it from pumping up the front tires to 35psi from 28? (they looked rather squished with all that weight up front) or was it the lazy, unhurried drive home?
Both, perhaps. Drive TO work wasn't lazy, and the amp-hours used was lower than average. That would have been the tires...unless conditions were different last night.
Time will tell. It's certainly easier to steer now!
