RE: Synthetic oil (long)

["Hall, Phillip" <Phillip.Hall@msfc.nasa.gov>]

A lot of people do just as you say Bob and get good service out of their
cars.  Generally you only loss a = and maybe a full quart changing the
filter only - depending on the size of the filter and orientation.  Longer
oil changes using a synthetic is a benefit, but the greatest benefits are
reduced wear, maintains viscosity at high temps, flows better (much better)
at cold temps, and suspends dirt much better - just to name a few.  This is
especially important on older motors,  high RPM, turbo motors, or if you
drive at all hard.  Personally I like knowing I have the best in my Roadster
as it hits 6500 RPM.  The cost of a good synthetic is small in Roadster
land:-)

        Just a thought .... if you feel the need to replace the oil filter
every 3K
        miles (which I think is important to do), then why not just go ahead
and
        replace the oil with new oil at the same time.  You have to drain
the oil
        anyway (right?) to replace the oil filter, so why use expensive
synthetic
        oil when you might as well use new, clean, regular oil that will be
fine for
        3K mile duration???

        Thanks for the inside information, it will be really helpful!  I run
my
        67.5 about 12K/yr and am leaning towards Mobil-1 after I rebuild my
        engine (and break in).  I will probably extend the time the oil is
in
        the engine, possibly 10k, but will continue to replace the filter at
3.3K
        to keep the solids down.  Any feeling on this?  

        After reading the subjective oil filter tests that was posted here
some time

        back I will also probably go with the Mobil-1 oil filter also,
unless
        something
        better has been found.

        My roadster is my daily driver and I want to keep it as reliable as
I can.
        I would rather put $$ into it than put much more into a new car that
is not
        anywhere close to as fun to drive, let alone not nearly as robust!

        Thanks for the good work!

        Peace,
        Pat
