Tranny Oil: which ATF type other than Mercon

What ATF number is recommended for my '98 Mark VIII LSC? I purchased 7 qts. to service my tranny and a new filter / gasket kit of course. I took the auto parts guys suggestion to go with Valoline synthetic AFT #4. I got home and recalled a friends story years ago that it is very important to use the correct tranny oil specific to the manufacturers design or you and get yourself in trouble in a blink of an eye. Not to say the autoparts guy was not correct, I just want to double check and confirm from another source. My full service factory manuals just state to use Ford Mercon or equivalent. The Valoline site was no help either.

Also, anyone have any bad luck with adding a qt. of Lucus tranny conditioner? They claim less friction to internal parts, less heat, etc.

Thanks....
