I concur with both observations above. Driving around town won't do it. Get it on the freeway and oil temp == water temp. But it won't happen until the engine runs above 3000RPM for a while. From starting my water temp gets to operating in about 5 minutes; in stop and go oil will catch up in about 15-20. Mine is a Roush 427 and the oil temp sensor is in the pan.

If you have an oil cooler on a street car, your oil will never get hot. Unless you're driving in Phoenix in July.
It will warm up (as does water) in stop and go traffic, but like above, tends to equalize to water.
