Oil Light keeps going on-Help!!!

Ok this is really weird. First off, yes I checked the oil and there is more than enough oil on the dipstick so thats not the issue. This has been happening for about 3 weeks. And it started happening right after I got an oil change at the dealership.

A few weeks ago I got in my car, started it, and noticed the oil light was on. So I immediately turned the car off and checked the oil. I knew I had enough oil because I got an oil change at the dealer literally the day before the oil light came on. So I checked the oil and everything was fine, it wasnt low it was 75% up in the ok zone. So I turned the car back on and there was no oil light. I thought it was just a fluke.

So fast forward a few days, and the same fuckin thing happens. I start the car in the morning, the oil light goes on, I check the oil, its ok, start the car again, and everythings fine.

Then a few days later the same thing, I start the car, oil light stays on. I even wait a few seconds, maybe a minute and its still on. I turn the car off and turn it back on and now the light is off!

This has been happening a few times a week, maybe 2 or 3 times x week but not everyday!!! Does anyone know what could be the problem? Did the dealership maybe use the wrong oil?? The light always goes off once I turn the car off then back on, and no, I am not out or even low on oil.

Anyone???
