my oil pressure on hot engine with full throttle to the rev limiter is 37 psi !
I am affraid it is too low, the car runs perfect, engine is quiet but i dont know whats happen. Can i drive with 37 psi to the rev limiter?
At hot iddle my pressure is 22psi

 

workshop manual stats 2.5bar@2000rpm

 

Hot idle doesn't look too bad, but i'd be expecting 50psi in the top half of the rev range.

 

when was the last time you changed your oil? if the oil is old and thin you will lose alot of pressure

 

oil is good, pressure is the same just after repleace it

 

What oil you using? Is the engine high mileage/worn?

 

engine is 9600km , oil is yacco galaxie 15w50 competition

 

What gauge do you have?
I have an autogauge one, and according to that i have 12 psi at hot idle, and about 20 while cruising, i think it tells lie's!

 

VDO gauge from audi

 

Are you using the same sender that was with the gauge in the audi ?
37 doesn't sound that bad, I would have expected a little higher maybe 45psi.
