Nope, with the key in on, the oil light is on. The moment the engine starts it goes off. Even following an oil change. I have seen other cars where it takes a few seconds to build pressure. I let the engine idle for a short time on a cold start, and a few minutes on very cold days. Usually I wait for the RPM's to drop below 1500, and 1250 if I have time to spare. I am still considering an oil pressure gauge, but it would be part of another project that I don't want to spend the money on right now.
