Stay Outa Them Bars

Just as it should.  When RPM drops and oil is warm, pressure drops.  
My rule of thumb is that if I have 10 PSI/1kRPM, Alles Is Gut.  Your 
engine has LOTS more pressure than that.

Well, let's just say you're running where no one is pursuing.  Here's 
the ole' scuba diver method of interpreting this Deutsches gauge.

1 Bar = 1 ATMosphere, Jah?     Und.....
Scuba divers know that 1 ATM @=15 psi at sea level.     Ergo.....
1  Bar @= 15 psi.      Ergo....
Your car has @30 psi oil pressure at idle, which is EXCELLENT! (clap 
hands together here and imitate playing guitar...).  And at road speed, 
you have almost 75 psi.  Whoa, dood!  What totally bitchin' oil pressure!!!!

I'd like my medication now, please.......
