I know this sounds like a strange question. One of my Pennzoil 5qt jugs sprung a leak. I had an empty 1 gallon bleach bottle laying around that I was saving for used oil disposal. I was wondering what would happen if I poured the new oil (only 4 quarts) from the leaky jug into the empty bleach bottle. Would any of the sodium hypochlorite residue effect the oil? I did not pour it in, but was wonder what would happen if I did. I just put the Pennzoil jug in a plastic bag, and turned it upside down.
