Thanks BigBob: I am using 5W/50 Castrol Syntec (fully synthetic). If the light and thin synthetic oil is the reason for the light coming on should I disregard it or change back to mineral oil?

I have been noticing that occasionally the oil pressure light comes on. It happens in low rev situations. It always flickers out. In the summer, I would notice that the light would stay on a little more than normal (about 3 seconds) upon startup. Now that cold weather has come on, I have been noticing that it stays on even longer upon startup when it does come on, and occasionally it comes while I am at a stop light or parking lot. Again, it does not occur often. What could it be?

What weight oil are you using? Also you could have a bad connection on your oil sending switch. It's loacted behind the cylinder head on the passengers side.
