You are in the minority then. Its been my experience after 20 years,
sometimes less, they all pretty much do it. In fact, my old 94 E420
even did it. Usually when you turn the key on before the engine is even
running you will see the guage flicker, sometimes move as far up as
half. Its the sender is completely bad, or the ground, it will go to full.

I took two 300E's well past 300,000 miles and saw no electrical issues with
either. But you are right, it's easy to tell the difference.
If the jumping around is random then it's electrical. If it's not so random
(pulsing at idle, drops at warm-up) then its not electrical.

Well these guages are electrical, its quite obvious to look at it that its
jumping around from electrical issues. When I had it it would jump up to
3 at idle often. Quite common problem on these cars.
My experience has always been main bearing problem = low oil pressure at
speed.
Seems like the viscosity may be too low -
It's *supposed* to go to the peg by 3000rpm =
For a 300E gasser I'd run 15W50 year round -
possibly 20W50 if available and it is a hot area of the country -

I don't think you are being anal. Oil pressure that bounces between 0 - 1
BAR at idle & then goes full scale at road speed is not the gauge, it's
the
oil pump or main bearings!

Is that the gauge or the sending unit? I'd like to fix it.
Just so you don't think I am totally anal -- not yet to be ruled out --
I
had the philosophy drilled into my head for years that you *trust your
gauges* (while having fun way up there in the sky, and actually being
paid
to do it) and react accordingly. If oil pressure falls to 0 on one of
the
engines, you don't say, "Oh, the gauge is flaky." You beat feet for the
nearest airport and review your feather-engine checklist.
Occupational hazard I just can't seem to shake.

Nont to worry about the oil pressure, the guage on that car is a little
flakey. It will bounce from about 1 or so to 0 at idle. Real reading
is
about 1 to 1.5.
