emergency.

I've been there, and I made the opposite decision.

I was 30 miles from Raleigh when my oil pressure gauge got flaky
exactly like that. I figured it was just the gauge, and kept going.
I almost declared (I was talking to approach), then I almost declared
again when I got handed to tower (who vectored me away from the field).
But I didn't, because I figured I'd look like an idiot if it just
turned out to be the gauge.

When I finally got on the ground, I opened the cowling to find that my
right mag had backed off it's studs, and was dumping oil everywhere.

I had between 1 and 2 quarts left in the engine.

You made a good call.
