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?
