I am ordering the 6 gallons of rice bran oil from Riceland. At only .1% use of T-50 if I added it to preserve each gallon would be 12 oz per gallon. That will get expensive with the price of the T-50! Is there another way to preserve all that oil that is less expensive because it is going to take me a while to use all that up. What about freezing it? Thanks in advance for any advice you may be willing to offer.
