All of the above posts are still valid info. If the cars haven't changed in the last 4 years, why would posts about them? Just sayin'

I have a 2 gallon jug I take down and fill up before I do filter changes. Fill up the filter, then pour the rest in the tank. If I'm feeling lazy, I disconnect the fuel line by the tank to fill up the jug a little...

I would worry about the redish ATF being returned to the tank. While I've never personally had my tank dipped by the authorities, should it ever happen - I don't want anything of a reddish nature in the tank. Red is what they dye farm-grade diesel with. If you are caught on any US road with red dye in your tank, it's a very hefty fine. Akin to tax evasion.
