did you all not see the news recently(within the last 2 weeks) that they left mcdonald's food out and it never began to go bad or decompose. I think they did the test on burgers and their chicken nuggets. Can not remember the exact length of time the test was done, but it was something like 6 months.
As someone else mentioned they use the same oil over and over, eventually it is more of a sludge than oil. Eventually the oil is going to break down,like your car oil would if you were to go 20k and not change it.
