Default Oil alert

I was about 500 ft from home yesterday when the warning tone and the oil symbol appeared in the instrument panel and oil appeared on the speedo. it then went out when I got home I checked the oil ant it was full ( I added a quart last week).
Any one have idea what might be going on?

None, not any because you posted in the generic forum section and did not provide Year, Model or Miles.

Could be simple, like a bad pressure sending unit or a failing oil filter. Could be nasty internal damage or blockage. I would start with the east stuff. When was the last time the oil & filter were changed and what oil and filter are you currently using?

I had the oil changed in early April just before a 1600 mile round trip to NJ. I do not know what brand but weight is 5w-30.
Millertime045 what was the reason and how did you solve it?

Is there a you tube video on the replacement? How hard is it to get at.
I was going to replace the valve cover gasket until I watched what was involved on you tube
