I myself think you would be fine running 2 gallons per tank. ATF has a lot of detergent in it and should help clean stuff up I would think...
I have heard of using ATF in your engine just before an oil change to help clean it some. Drain about a quart out, top off with ATF then run it for a bit. Then drain and refill with fresh oil & filter. I have done it. Never have heard what the magic # is for time or miles. Since I have been using Pennzoil/ Shell with the cleaning additive I no longer use ATF. I really like that oil.
