The first post I ever made to blind Handy Man was around this issue, and I propose that an individual take a length of vacuum hose and lowered into the tank while blowing on the upper and. You will hear the bubbles and feel the resistance when you hit the oil. With a little bit of calibrating, with twist ties etc., you got a gage.

I suppose one could get a sensor that they have in automotive tanks that causes a light to go on when gasoline gets below a certain point. They work by a thermocoil. Normaly the liquid cools the coil, but when the liquid gets below the coil, the coil heats up and closes the circuit. Instead of connecting it to a light, you could connect it to a buzzer. I've bought buzzers that run on 12 volts at Radio Shack. The thing could be powered by a 12 volt transformer using household current.
