I've got some questions. They may or may not be dumb; I certainly am.

What does it matter if the gauge doesn't go above 100? The oil pressure only reads over 100 on startup, right? So if the gauge maxes out on startup then why does it matter if you can read the extra 20 psi or not?

I mean if it damages the gauge or something that makes sense, but I've never heard of that. I got my gauge to make sure my oil pressure doesn't drop too low. What would be the need to check oil pressure when it maxes out?
