First thing to do is recheck your oil level, just to make sure that you haven't sprung a leak. It could just be a bad oil pressure sender. If this is the case, then it is just a coincidence that it happened on the changeover from 20/50 to 10/30. You don't say how many miles are on the engine. If high mileage is a factor it could also really be a bad oil pump although they're usually pretty robust. The absolute best thing to do in either case is to test the actual pressure with a mechanical gauge. You should be able to pick one up at AutoZone, or have it checked at your local garage.
