Occasional Oil Pressure Light for 2-3 seconds in my 318. Should I panic?

My oil light would come on intermittently...scary when it stayed on! I pulled over and the engine was idling smooth and not overheating so i just drove it home.
I screwed in a new sending unit and the oil light never came on again.
I'd try that first if i was you...10 minute job and a few bucks!
Seriously THIS is the 1ST step.
Typical forum answers making you do the hardest thing first like pulling a pan or plumbing a gauge.
Just change the sender and see it it goes away.
If the engine isn't changing tone I bet it is this.
My sending unit with a Guage went bad randomly it did the same thing.
Could also be a loose wire.
Easy first then progressively harder.
