Air compressor from fire extinguisher - video

I am a bit more worried by the fact that he used a possible oil base lubricant on the connection between the regulators and the tank. You shouldn't use ANY oil substance on it. Oil base substances can cause an explosion under pressure!

Really? Because I have definitely done this. I've poured oil into air tanks as a corrosion inhibitor, and I've filled compressor sumps with 10w30. Vacuum pumps too. It's not exactly good practice because you're supposed to use non-detergent oil, but otherwise I've never heard of this being a problem. How does it cause an issue?
