I'm always amazed at how much we Cobra guys love our "Snake"
oil. Back in the 50s I had an uncle who added 1 quart of kerosene to every
oil change. As best I can remember he never had any trouble. It's probably reasonable to assume that if MMO belonged in our
oil, Mobil or Castrol or Pennzoil would have already put it there. As far as adding it to the gas I would be very cautious, a clogged injector or gummed up carburetor can ruin your whole month.
Just my $0.02
