i dont get it, why would a piston rust? our fuel is of hydrocarbon or short, carbon...

while IF there's rust on piston, it's oxide..

if not mistaken, carbon + oxide + heat = CO2+H20..meaning, even if there's oxide or laymen term rust, it'll still be removed..

dat's y we didnt hear ppl complain of inner part of exhaust system tubing gets rust..usually the rust sets in from outside..
