It's motor oil, not medicine, live bait, fresh meat, or produce. The stuff sat underground for millions of years at he11ish temperatures before being pumped to the surface. It then underwent similar he11ish temperatures during the refining and hydrocracking processes. (As far as anyone familiar with the proceeses know, none of it went "Pffttt" in a smokey flash like the audio tapes in the opening of each
Mission Impossible episode either...) According to the product data sheets, it's designed to withstand temperatures in excess of 400 degrees F. in the presence of oxygen before flashing. And y'all are worried about its shelf life at ambient temperatures? By the way, those with half a clue would look up a few material safety data sheets online instead of revisiting this tired topic every two or three months. Without exception, they all state, "
indefinitely" regarding refined and additized product stability when stored at ANY temperature within human tolerance in sealed containers.
