Why is my Vauxhall Crossland's oil pressure low?

I noticed my Vauxhall Crossland's oil pressure gauge is showing a reading below normal. What could be the possible reasons for this and what actions should I take to remedy the issue?

Low oil level is the most common cause of low oil pressure. Be sure to check your oil level and top off if needed.

A faulty oil pressure sensor could also be the culprit. Have it tested and replaced if necessary.

If you've recently changed your oil, make sure the correct viscosity was used. Using the wrong oil can affect oil pressure.
