That's right, plus possible causes for the oil pressure being low, that are
reasonably easy to fix:

4. Bad oil pressure regulating valve, replace plunger and spring.
5. Worn oil pump, rebuild/ replace.
6. Oil diluted with petrol, could be nothing more sinister than a bad spark
plug or -cable. But then you'd probably note the power loss.
