    Ok guys I know this is an old argument but would like to rehash a bit ,I know many say to mix 16.1 on old 1950s evinrude motors and back then that’s what the manufacturer recommend however oil back then was crap compared to today’s oils,I have talked to 2 outboard engine mechanics that have worked on many old and new motors and said mixing that rich with today’s high quality is just not necessary they went on to they have seem many that use pensoil had a very high build up of carbon They told me it safe to mix 50.1 in my 3 1950s evinrude motors using Quicksilver oil made by mercury that was plenty of protection with a high quality oil , what are your thoughts, thanks

    ..well I’ll bite…

    I never run leaner on oil then 32/1 in jeweled stuff and 16/1 on non-jeweled motors.

    I run 3oz. per.gal., about 42 to 1, in most all
    my motors from the 1920’s up to the 1960’s
    including the one in the video below.

    I would say that’s proof what kind of oil do you use

    The oil I’m using is Pennzoil Full synthetic.
    It’s no longer being manufactured and I will
    likely run out of it next summer. I will likely
    go with another full synthetic but I believe
    using a synthetic blend provides the same
    protection. I choose a full synthetic because
    I believe they are more environmentally friendly.
    The Pennzoil claimed to be biodegradable.
    You see it is the worst of times.
    (Will outboards and inboards be next in
    California?)
    Would using a biodegradable oil and reducing
    the amount have lessened the assault on 2
    cycle motors? Probably not. It still maters
    to me what I put into the air and water.
    I try to be as clean as I can and still run my
    motors. I was born in 1946. When I go to the
    dentist I don’t want the recommended
    procedures from 1946.

    An event should be organized at one of the larger meets to see just how little oil can be used in motors running at WOT for an extended period of time. Different classes would be needed for RBM’s, low compression trolling motors, and high compression high horsepower go fast motors. Whoever blows or burns up their classic/antique motor last in each class wins!

    Anyone found using factory recommended oil ratios would be disqualified for cheating.

    Excellent idea, Mumbles ! It’s always struck me odd that the same folks who are anal about originality insist so strenuously on not following original fuel recommendations.
