Proper oil pressure

Recommended Posts


As a new owner of a 03' C4 Cab from a 00' Boxster S, I have a few more gauge's to worry about. One is the oil pressure that seems to be running a little high. The manual says it should be between 3-4 bar at 5K rpm. I am still breaking in (only about 600 miles so far) and do not run that high yet, but it seems I am normally seeing 4-5 bar at about 3.5Krpm. In the morning, when things are cold, it seems to peak out at 5 bar for first 10 minutes or so - maybe normal?

Question, what do others seem to see as "normal" running oil pressure? Also, does my experience so far seem appropriate/acceptable or perhaps reason for concern?

The same thing made me really nervous. I topped off my oil and only then did i notice the oil pressure always going really high (to 5) anytime i stepped on the gas. I checked with the dealer and they said it was normal and i double checked on my friends 02' C4S. Same thing happens in his. I was getting really nervous until i noticed i wasn't the only one. So i guess it's a normal occurance despite what the manual says.
