Hi all,

I'm new to the forum scene so this is my first post.

I have a 1997 EL Falcon XR6 and I recently rebuilt the engine as it had 350,000 KM's on the clock.

After I took it for the first test drive after the rebuild I noticed my oil pressure gauge light was on and beeping. I bought a $30 gauge from Autobarn and checked the oil pressure which was really low ( 8 psi when idling and 35 to 40 psi when driving 1500-2000 RPM at 80 KMPH).

I thought maybe it could the oil i'm running which is Nulon 15w40 running in oil or the JP standard replacement oil pump which I put in.

I Forgot to mention, when the car is cold the stock oil pressure gauge was in the normal position ( just over half way) and the aftermarket gauge would read 45 psi when idling

If you guys have any ideas that would be great.

nothing wrong with 8psi at idle and 45psi at 2000rpm
