Ooh! I'd love to see how this works! There's a whole bunch of Transmission shops right down the road from me.. I'm sure they wouldn't mind free disposal of their fluids.

Only question I have, is how safe is this for the engine, say, with a 75% Trans, 25% Dino mix? I don't feel like pouring a few gallons of filtered, used transmission fluid, into my gas tank.. only to find out it corroded my fuel lines, clogged my injectors, or worse.. a few months later.

So uh, how well do I need to filter the stuff (as in, with what?).. and how safe is this?
