Wondering if anyone else has ran into this... Went out today & upon leaving the dock the low oil horn sounded. Added a gallon { Wal-Fart  brand}. Ran for about 3 hours, horn sounds again, ate another gallon.. Burned approx. 17 gal. of fuel. I just put new plugs in in tues.  the old plugs looked to be burning normal, not loaded with oil.  Seems to some a little much ate idle  & cold starts. Other than that runs fine, no hesitation, 5600 RPM's flat out . Any  suggestions?
