For anyone (like me) who didn't know what NTC was, it apperas to be a type of thermistor (that is, thermal resistor) with an inverse relationship between resistance and temperature (temp up, resistance down, the NTC stands for Negative Temperature Coefficient).

Googling, I can see that this is a fairly common use of NTC Thermistors, but why does it work? Is the liquid gas that much cooler than the air above it?
Also, the Flyer says that it's a 3.5 kOhm NTC... is that the R25 or what?
What ever happened to the Flyer? It looks like he never got around to posting the oil sensor instructions....
