I refrigerate my oil in the summer. I use a tea leaf sieve and strain the oil as it comes out the valve. I keep 4 resealable gallon jugs and put them in the shop frig until the temp gets moderate.
I don't know how long oil will last, but I cooked 45 lbs of catfish fillets, 30 lbs of fries and 10 lbs of hush puppies and all I did was strain the oil and it was ready again. That was over 4 hours of cooking and it did not burn the oil! I knew right then I made a good investment.
