A 7.75 mile drive burned 3168mAh or 408mAh/mile, after adding a turn to the right pushrod to make it toe in more.  It carried a hefty load of food for the final mile.  Range correlates with the total number of turns in both pushrods, not which pushrod they're in.

Theoretically, marking the tires with chalk should give the toe alignment in the form of smearing.  The internet shows guys using string, but the wheels are too small & not the same spacing.

A 10.9 mile drive burned 4230mAh or 388mAh/mile, after adding another turn to make it toe in more.  It was a very hilly route.
