Fluctuating Oil Pressure Gauge

[DocMarshall]

I've recently noticed my oil pressure gauge fluctuates while driving at steady speeds on interstate. Normal? I've never noticed that before. Thoughts?

TIA

When was your last oil change? When mine did this it was lack of oil.....

These engines have a variable oil pump; the PCM controls pressure based on various parameters, the most apparent one being load.

PV=nRT

n, R, and T in this discussion are constants.

Engine using a variable pump on a fixed volume. Thus, pressure must change.

You're just fine.

What is the normal range for engine oil pressure?

What is the normal range for engine oil pressure?

It varies depending on operating conditions. Anywhere from 20-70+ PSI.
