I have a 1995 Chevy Lumina with the ''Low Oil'' light on.

You should be leaking something, which would mean you should also be low on a fluid after driving.
Are any of the fluid levels low now ?
You may have to clean off the engine to find the source.

You may need a mechanic for this.
The strong gas smell and the hard starting could be connected.
You could have a leaking injector, or faulty pressure regulator. And you could have a fuel leak in the line.
A mechanic would do a visual inspection of the line from the tank to the engine, and check the cylinders for raw fuel when the engine is off.

The fact that the oil was low would not be from the oil pump, but from wear in the engine. If it is not smoking when you start it or as you drive, you can probably keep it running by just keeping the oil level checked at each fuel fill-up. As for the car shutting off, you didn't say if the engine seized or got real hot. A low oil pressure problem should have triggered a warning light before the problem got to the point where you lost the engine.

If the car ran after you added the oil, you got lucky and need to always check it.

Sounds like the oil pump has given out or the pick up screen could be clogged up. You will lock up the engine if you try to run it this way. Have the oil pump checked as well as the pick up screen.

check fuel pressure most likely bad fuel pump. also check your oil sending unit or gauge. chevys run the fuel relay to the oil pressure switch in case the oil is so low the car wont start. sometimes the relay in between this circuit goes bad as well. if all is well check or replace the ignition module (located directly under coils) or distributor integrated if it has a distributor

some cars with oil level warning light on, it doesn't mean that its only reading the engine oil level is low, sometime the transmission fuid too. Did you check your transmission fluid if it is ok or not? try to check and let us know, ok.

If you changed the oil filter at the same time check that it hasnt come loose and leaked some oil though there would be signs of that where the car site. If it is overheating check your water as well.

Also check the oil for water and the water for oil as you will want to make sure that you havent done any head damage or blown the gasket.

yourgoing to have to drain it from the pan just pull the drain plug and let it all drain. change the filter and then replace with 5 quarts of 10w30 oil perferably quakerstate or valvoline brand

sounds like a leaky oil presure switch. they will leak oil out of the wires comming out of them sometimes saturating the connector of the switch. If that isnt the problem then your oil pump is weak causing the lite to come on or your leak is so bad your oil level is so low the lite is coming on

OK WELL HERES HOW TO RESET UR OIL LIGHT TURN THE IGNITION ON-AND STEP ON THE GAS PEDAL 4 TIMES AND UR OIL LIGHT WILL BE RESET THIS USUALLY HAPPENS WHEN YOU DO A OIL CHANGE UR SELF THIS ARE TRICKS THAT THE GM HAVE HOPE THIS HELP
