    Hello all, thank you in advance for your help. I was not able to find what I wanted to know in a search here. The owners manual says to use Mercon ATF power steering fluid in a '98 Mark VIII. Can you use Mercon V today in it? If so, is it ok to use Mercon V if some of the original ps fluid is still in there? And how much ps fluid does it hold?

    *Edit* I found this TSB (07-1-7) that states the '96-'98 Mark VIII should switch from Mercon ATF to Mercon V for power steering. Can these two fluids be mixed at all?

    in our 1997 we've used off-the-shelf PS fluid with no ill effects in 86,000 miles. But it doesn't leak any either ...
