I have heard from some old-school racers that all of those coatings do help to make power in full-tilt-boogie race motors. Oil shed on the inside of the block (gets oil back to the pan faster), knife-edged crank throws, boat-tailed mains (help with air flow management inside the engine), teflon wrist pin buttons, and so on.
Many of them are only intended to work at high RPMs, which is not where fuel economy is found. It would be interesting to see what good any of them would do for MPGs.
