Hello Sniper!

Very strange! I have seen people put bar lube in the gas tank accidentally. I have never seen this happen, but if it is an automatic oiling saw, it could have leaked past the diaphragm that pressurizes the oil chamber. This diaphragm is operated by pulses of pressure from the engine crankcase. Unless someone actually put the oil in the cylinder for some reason, this would be the only way for the oil to get in there.
