Oil Pressure Gauge

Recommended Posts

Have a 2004,C2,six speed,15,000 miles,using Mobil 1,0-40 synthetic oil. I am noticing that the oil pressure gauge fluctuates up and down,never much,it doesn't go low,or too high,it just stays put or jumps around a very little bit,so the pressure seems to be ok. 4-5 bar at 3000-5000 RPM,1 1/2-2 at low,idle RPM. Should I be looking for trouble here or is this reasonable?

Any thoughts would be appreciated.

Those numbers mirror what I see in my '02 C2.

I am not concerned about the pressures,but the minor jiggling or moving slightly up and down at a given RPM that bothers me. It usually goes up or down as RPM changes,smoothly,and remains stationary as the RPM is constant. It' jumps up slightly and then back erraticaly. Thoughts?

I would clean up the connectors on top of the oil pressure switch to start with.

I would replace the sender as it sounds like the wire wound pot is starting to fail.

Sorry to drag up an old thread - was there a resolution to this? My pressure gauge jiggles a bit too and looking for solutions unless they all do it?

They all do it mate, don't worry about it, you've just got a bit of the classic "porsche paranoia"

Ask your mechanic next time it's in for a service.

If it reads 0 and you have a warning light on then start to worry, otherwise, enjoy! :)
