I took my 4.0 XJ for an oil change yesterday and a new guy put in 6 quarts of oil rather than 5. My oil presssure guage is now pegged. While I suppose it would siphon off eventually I'm going to take it back today to have them make it right. Aside from damage to the guage, is there anything else I should worry about?

Anyone who wants to bust me for NOT changing my own oil in subzero weather, have a field day,..... but I'm only seeking constructive information.

Double check that they did not break your oil pressure sender (when swaping out the oil filter). A cracked sender will also peg the gage on some model years.
If it is cracked, a quick fix is a M10 screw until a new sender is obtained. Oil does not leak out of a cracked sender because of a thin membrane in the sender, but this can fail as I found out the hard way many years ago.

I vote for sender as well, too much oil will not cause high oil pressure.

If you take it back and blame them for "too much oil" causing a high pressure you will look dumb. they will then turn around and say "hey look your sending unit is broken, we can fix that, for a fee!

Definitely. That sender is about 30 bucks or more. Very easy to break during an oil change if one is clumsy. Make them buy you a new one.
