yes thats common, this motor had 3gal on and recently new bearings and con rod was new, it was original crank but showed almost no wear only 3gal. i do heat cycle for break ins, and preheat before starts for about 1/2 gal afterwards. i did have a lightweight flywheel on it, might have over revved it.
