Where would I get soybean oil (large quantity)?

Just talked to an extension agent who recommended diluted soybean oil to spray on trees with gypsy moth infestation. They buy it in 55 gal drums and spray the webs with super-soaker guns. I don't want THAT much, of course, but probably not a 16 oz bottle either. Any ideas appreciated.

Have you tried Costco or Sam's club? I'm not sure if they have soy oil, but whatever they have is usually in large quantites.

You could check into a buying club or co-op.
I know our buying club offers oils by gallon size.
