I Increased the oil in my lawn mower to 18oz, now there is a visible but faint gray smoke coming from it, is this normal?

I have a Briggs and Stratton snapper lawn mower,

I now upped the oil from 12 oz to 18 oz.

Now there is a faint light visible gray smoke coming from the muffler. It isn’t smoggy but it is gray smoke it is mostly clear.

    Indicts that oil is burning, it will eventually burn off, too much oil can do as much damage as too little oil, always use the recommended amount for that motor.

    Why don't you try filling with the correct type and amount of oil as specified by the people who designed it ??

    oil smoke coming from an internal combustion engine usually means you are burning oil.  possible causes: worn rings and/or valves, excessive quantity of oil in the machine, blown head gasket  -- grampa

    B&S does not use oil.  Overfilling means early destruction.  You are forcing the machine to slog through oil that should not be there.  Follow directions or cut the lawn with hand scissors.

    The engine is burning off the excess oil you put in. {Been there, done that.}
