  1. My grandfather fed his family with firearms that used nothing but 3 in One Oil (the Original that still comes in the same little can. The same stuff granny used to keep her ‘foot peddle’ Singer sewing machine singing has a sacred spot on my cleaning table.
    WD 40 (not a gun oil) jammed my 1911 and a dose of that old 3 in One got it running again. Never the less, the newer stuff is pretty good too. I like Ballistol in either the little spray can or the liquid 12 oz. can.
