From the article:
“Oil does not have a long shelf life, and while we used oil, we never made the effort to break this five-gallon container into more accessible containers because it was deemed “for an emergency.” This weekend we found that it was over two years past its expiration and will have to be discarded.”
Something I’ve learned is DO NOT THROW AWAY RANCID OIL!!! Even though it may not be consumable as a food, it can still be a fuel source! I even have a non-petroleum based chapstick (made from vegetable oil) which has gone rancid, and I’ve put it in our go-pack in our fire starting supplies.
I have never been faced with rancid oil that had to be thrown away. I have read about some people using old oil from restaurants and making fuel to run motors, but have no idea how that works.
