Oil level and pressure

[WetherbyPorsche]

Hi all,

I recently acquired my first Porsche:

10/2002

C4

Cabriolet

6 speed

25,000km

LHD from Germany.

I received the car 3 weeks ago in perfect condition with the full servicing done late January 2006. At that time, when I was starting the car, the oil level would show full level on the board computer, and oil pressure would be around 3.5 bar at 3,000 rpm :D .

One week ago, I took the car to go for a 3,000km tour around France. Everything was fine.

But last week-end :( , when I started the engine the board computer shows the minimum level of oil in the engine, and oil pressure is now around 4.5 bar at 3,000 rpm (even near 5 at high rpms :eek: ).

I was wondering if I should put back some oil in the engine (if yes, please advise me for what you would use), and if this is normal to consume that much oil for 3,000 km?

Also, after having spent some time in the RennTech forum, I was also worried for RMS issues, but there is absolutely no traces of oil leakage on the ground when I move the car.

Thanks for your help.

Congrats, sounds like a great machine, I am biased to cabrios, living in the Southern US.

The oil level, if the car is not on a level surface, the dash will show the wrong level. Do not add oil, measure only on a level surface, and use the dipstick as the real measurement. The dash I would consider secondary.

Thanks.

I will look at it tonight. Also, do you any clue as to the normal pressure level of the engine?

Oil Pressure:

Cold engine, all speeds - 5 bar

Warm engine, idle - 1.5 to 2 bar

Warm engine, above 3000 rpm - 4 bar+
