This. Diesel is much more stable. Vegetable oil is soybean oil, an oil that will polymerize as fast as linseed oil, both were commonly used for paints. You've heard not to leave oily rags sitting around. That actually has nothing to do with an oily rag that you wiped engine parts off with, motor oil is very stable. It has EVERYTHING to do with a rag that wiped up oil based paint, polyurethane, LINSEED OIL, or soybean oil. Your wipers soaked with soybean oil are an ideal spontaneous combustion device.
Re read the post. I guess I'm disagreeing. Avoid soybean oil. Used motor oil would be much less likely to combust?
