I had a good old sniff at the sunFlower oil tonight, and blow me over and call me a fisherman....rancid. Did need to give it a GOOD sniff, but yes sir, as rancid as an old fishhead. Yuck yuck and more yuck, I OPed with RANCID oil three times for 15-20 mins each time. No wonder i felt like a sack of ...... with that stuff running through me!
