Just for your information, I used to see a couple of suppliers list a container as one "gallon" but then listed the weight in parentheses. I'd see 1 gallon (7 lb), 1 gallon (7.5 lb), etc. (However, one of the suppliers has ended that and now just lists the oils in pounds which I think is more accurate.) This is why I was questioning what the actual amount or weight would be since I always weigh oils and I've never used ostrich oil. Also, it's only listed as one gallon on Indian Point Ranch's site. For all I know, it may only be 120 oz or 7.5 lbs.
But thanks for the reminder that fluid ounces are different from net weight ounces. I was basing my calculations on 128 oz by weight and not volume. I won't know the volume until I get the oil.
