oil molecules

[jmcelroy@lr.net (Lynn M. McElroy)]

      Hi all,

        If my memory serves me right, I was once told that once you chose a
motor oil you should use said motor oil exclusively from then on, because
the oil molecules bond to the engine's moving parts, and any mixing or
continually changing from brand to brand of motor oil may have adverse
effects on this bonding process.
        Maybe it doesn't matter at all. Can anyone enlighten me on this
matter? THANKS.
