Default Blinking oil pressure light at idle sometimes driving

As I wrote on the subject, that light is blinking but is occassional. Mainly at idle.... Can it be the oil grade? Do I need a thicker oil?
The mechanic change the oil ( it was full of gasoline) but I dont know which one put on the engine....
The Odo is not working ... So i dont have the real miles on the Volvo.
Any ideas or advices?

Loose wire at the sender
Or cracked insulation on the sender wire rubbing and grounding Out.
Is it the 1993 240?

Gauges and idiot lights lie.
Verify with mechanical gauge.

Get an oil pressure gauge
Idiot light comes on at 1/2 bar
Your idle might be too low to keep above 1/2 bar
Or maybe you need pickup tube seals they fail after a while and you look paw pressure
