Thanks for all the great and quick feedback. I do feel much better now. I had no idea oil pressure could drop so low and not necessarily be an issue. I will change my oil and filter ASAP and will run straight 30 or 40 weight oil going forward. I can only assume that there is currently some thinner oil in it now, and as long as I avoid any 5,000 RPM runs tomorrow night, I should be ok. I'll just watch the gauge like a hawk.
Well I'm too late to respond for your "tomorrow night" trip, but..
I was going to suggest that you add a quart of straight 50weight (or as much as you can fit without overfilling), to bump your viscosity up a little until you can do your oil change.
