Donning my Nomex...

I seem to recall that engine wear is proportional to piston feet per mile.
How far a piston travels in moving the car one mile.

Given same lubricants, operating temperatures, the motor with more p-ft/mi
will wear out sooner.

Of course there are many other elements in the wear equation too but P-F/mi
seemed important enough to "Rod and Truck" to include as a parameter on
their road tests.

But if you wash your car regularly with re-claimed water you can feel better
about it's unstoppable entropy.
