Oil will not last very long. It’s a problem for long term storage. Lard will last considerably longer if it’s in cans with sealed lids (not that pull off aluminum crap), but it’s not “heart healthy”.
I have been doing some research on getting oil from nuts, since we have several nut trees that produce well on our property. I am also experimenting with sunflowers to see if I can learn to grow and produce oil from them.
I think it would be neat to be able to do it, and it could be useful in a long term hard times scenario.
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.
