Okay not sure if this is actual oil pressure as it's only just occurred.
Oil pressure gauge is fluctuating between the half way point and 275kPA on the gauge (so is the battery gauge between 14 and 12V ish although can be normal).
Going to get an oil and filter change. And have a garage look at the oil pump switch
Anything else to think of as possible cause?
Silverado 2007 4.8V dubious service history before 07/2023 when I bought it.
