Pardon my Question, But I haven't had a car with an actual OP gauge for many years. I've noticed when driving my '06 MX-5, that when I'm idling at a light, (warmed up) the OP gauge has a tendency to drop to 2 or 3 lines above the low indicator (fat line on left). As soon as I rev the engine or take off from the light, all appears fine. At 35 mph / 2000 rpm, in 4th gear, the gauge indicates "straight up" and actually goes more to the right as I get to higher rpms. The temp gauge is solid in the middle, and the car seems to be running just fine. Is it normal for an OP gauge to move around that much?

In a word. YES. You see, if you just want to see if the engine is running, then a simple light will do. If you want to see if the oil pump is putting out the proper amount of pressure for the RPM's the engine is turning, then you get an "oil pressure gage" and let it show you how it is changing. One of the reasons that Mazda went to a "non-reading" gage in the mid and late ninty cars is what you just asked about. Many people have never owned a car with a real oil pressure gage in it and they didn't know what to think when this "thing" kept moving on the gage. :-)

So you're saying " YES " this is normal OP gauge behavior ?
Thanks, Bruce...
I think that's what he's saying, yes. It's certainly what my OP gauge does and, from what others have said here in the past, it's what theirs does too.

Absolutely not, you need to give me the car and buy another one that won't do that!
Sure thing; Gwet back to me "After the Weekend"!
Yes, that's how my '91 worked. (that's how it should work.)
