So what you're saying is that for the biggest bang for my buck would be to have the cylinder walls treated. That's interesting because the engine building instructor at the local tech college once told me that fuel economy can be improved by the cylinders.

What would you say about having the treatment applied to the pistons, wrist pins, and piston skirts as well?
