Default Weird oil pressure gage.

When I first start driving my car like in the first 15mins the oil pressure gage will show the pressure rise and fall as I accelerate and decelerate. Is this normal, if not is it an easy fix?

Thanks again.

You're oil pressure should always increase with moderate acceleration. Does it change a great deal though?

Yes in the first few minutes of driving. For example if I were to say accelerate to pass someone the gage almost pegs. But after like 15 20 minutes the gage might move ever so slightly to not at all.

Before people freak about Trofeo'* oil pressure, remember that we're talking kPa. Metric......

Ok update to my problem.
I noticed that now it goes just past the 40 mark and stays now with little movement.
Then I remembered that I had some repairs done and that I hadn't actually seen it jump around since. The repair was a blown intake gasket.
