Took my '08 Turbo on a 300 mile day trip...highway driving, spirited...

I was paying close attention to the oil pressure gauge, and noticed that from about 2500 rpm's and higher the gauge pegged at 5....lower than 2500, the pressure decreased.

All other indications normal....quantity, temp, etc...

This is PROBABLY a normal pressure indication, and I PROBABLY have just never noticed it......?

Is the "5" at 2500+ rpm's normal?

Thanks...

When I first got my turbo, this is what I noticed as well and immediately pulled over to the side of the road and googled it. Found some threads either here or 6speed, but that is common from what I've read.

Mine is the same way. Its about 1.5 bar at idle and pinned at 5 anything above 2500rpm.

Thanks guys, figured as much

Normal, I replaced mine thinking it was bad. Same readings.

All is normal....oil pressure is going to change with rpm as the oil pump is spun by the engine. Faster the engine spins more oil pressure there is.

Normal, sometimes if you're a qt low it may fluctuate more.

The oil pumps are directly connected to the crank shaft, so the amount of pressure they make will relate directly to engine speed.

There's an issue if it's not making enough pressure for whatever reason. Keep in mind that if the oil is cold, it will be thicker, so you'll see full pressure at lower RPMs.

A number of manufacturers have switched from a sensor that shows actual pressure to a switch that will only change the needle state if the pressure falls below some minimum. This was done to cut down on end-user confusion.

However, if you get a good sense of what normal looks like with a proper gauge like they gave us in these cars, you can potentially spot a problem before it causes real damage.
