Not sure what that means.  In the context of oil coolers, if you have the
upside down cooler higher than the sump, it will drain back into the sump,
which means you are "overfilled" until the thermostat opens.  If you have it
lower than the sump, you are underfilled until the thermostat opens.  Most
oil coolers are mounted "oversump" which means they "should be" upright, and
in fact, most are, including audis own, motorcycle MC's etc.  Those that
aren't usually have a pressure ck valve in them which prevents oil drainback
on shutdown.   The cooler stays full on shutdown, oil levels vary the least,
thermostat open or closed.  I see this as a good thing.

Ok.  Referencing unto itself is an interesting concept.  Audis oil temp
guages are notoriouslly innacurate, it might be nice to have a more accurate
reading.  Right now, I'd say that's true of yours, since your readings don't
correspond with the thermostat operation by definition (or it is, and your
themostat is stuck open - in which case you have a water vapor problem).  You
have *done* something which is more than others have done, I won't knock
that.  What I will advocate, is that oil is a critical fluid, and any oil
cooler addition should be installed "as well as" what audi delivered from the
factory, regardless of the perceived performance.

IME, using a rubber line with an oil cooler means you have to pay dutiful
attention to them in terms of service.  The earls fittings aren't expensive
when adapted to your stock S car lines, and reduce the possibility of
failure.  Either will "work", and it's your motor.

Paul, only trying to be helpful here.  MacGuyver of an oil cooler install
isn't necessary, regardless of the uncalibrated claims.  Turn it 180 degrees,
rubber isolate it, and add some decent lineage, you've added a good piece to
oil temp peace of mind.
