Sounds like you blew a head gasket. Check the dipstick for milky like liquid, check the breather for the same.

sounds pretty dire. do you have any friends with a trailer?

the oil pressure light comes on when the pressure is very, very low. so assuming the car was still running ok, I suspect a broken oil pump, or something like that.

Thanks... heading to a hotel tonight (via tow truck) in Springfield, Illinois. Going to do more diagnosis once i get checked in.

Oil has a grey tint to it. If it is a head gasket... i have an extra set with me... could do it in the hotel parking lot.... actually. .. wouldnt have a choice.. would have to do it there. Good thing i brought all my tools

TurboBob has a good point also. I have seen the roll pin break that fastens the oil pump/cam sensor gear to the shaft. To check, just remove the cam sensor cap, have someone crank the engine. The sensor cup should rotate if the roll pin is good.

RIP racewaypark, NJ
oil pump drive gears can also crack and then the shaft cant spin the gear at the end
you have to be under 4psi for the dash idiot light to come on

If the engine has cooled down check the water level in the radiator.

If you blew a H/G and got coolant in the oil it should read higher than normal on the stick [depending on how long you drove it that way] and it will look white/gray.

Either way you would still have oil pressure unless you emptied the rad of coolant into the crankcase and took out the bearings. You need to be a little more specific, maybe post a pic of the oil on the stick to verify condition.

Check the rad to verify coolant loss or not. If the oil looks like grey mud it's coolant in the oil.

Take the oil filter off and see what comes out and snap a pic of that.

It could very well be an oil pump issue and not a H/G. Just need a little more info to give you an accurate answer.

Go easy on posting specifics of your where abouts etc., could be some low lifes reading this. How far is auto zone? Maybe try a cab or uber...
