TB, my old gunsmith -unfortunately not with us anymore- was a convinced
advocate of motor oil as a gun lubricant. His reasoning was that it had been
formulated for viscosity and to work in high temperatures -which the guns he
tended to in those days attained in use, as there were more birds or they were
used in competition- as a car engine does.

I too have "smoked" a number of weapons durring combat with cyclic rates of fire approcaing 600 rounds per minute but none of them were equipped with a hinge pin. And yes copious amounts of motor oil poured on the receiver will keep a M2 Browning 50 cal. operating when a dab or two of Moble One grease or Breakfree would probably have been vaporzed in the first two minutes but we are not talking automatic weapons here we, at least I thought, were talking about sporting shotguns that utilize two barrels and are operating at a maximum rate of fire at about 24 rounds per minute.
