How about the method of break in? Aviation piston engines' warranty is voided if you don't follow their guidelines: Install engine, run and check for leaks. Expidite to runway and take off at full power, initiate best rate of climb and hold for (something like) 15 mins. Land, change oil. Engine broken in.
Compare that to new cars, like my gf's new mini. 2500 kms under 4500 rpm and 115 km/h!
