Did you call the MB tech and ask him about it?
Using an infra red temp gun is a good idea to verify the gauge, but nothing should have changed there, but still good to check. If you change it out put the new one in hot water and make sure it opens, check the old one too.

Yeah, I called the tech and asked him about it and he said the 95 was normal and dont worry unless it gets above 100. I guess the fact that its only 5 degrees more until a problem is what had me a little concerned. When the car ran at 85...it didnt bother me. He also said, that the new Behr's are opening a little higher than the labeled 80 degrees. {Several posts on this forum confirm that}. I guess my original question was:
Do thermostats "wear out" over time like the one I had in the car? In other words does the
opening temperature decrease a little over time just from the multiple opening and closings on the thermostat "valve"?. Does the valve get weaker?
Is the Wahler considered a better and more calibrated thermostat than the Behr?
