I just used an old galvanized wash tub. But, when it is full, it is too heavy to lift and pour. So, I used an old coffee can to empty it into the empty buckets the new fluid came in. But, this wash tub gets used for other things (maybe I should consider one of those new fangled washing machine thingys for the wife) so I have to clean it out after it has hydraulic fluid in it. I like Dave's idea of cutting down an old plastic barrel.
