I'm assuming that's also why the cluster lights redline at 4000 when the motor is ice cold.

The oil temp is one of the most important gauges a driver can have!

Oil's basic function is to be at a sufficient psi between bearing surfaces to keep them from touching. To maintain this psi, you have to choose the correct weight oil for the operating temperature you're experiencing. For normal use, you are around 210 degrees or so, but when racing can go much higher. If the engine runs hot, you want a 'thicker' oil to compensate for the temp difference and maintain that psi. If the engine runs cool, you need a thinner oil.

Of course on modern cars the manufacturer has already figured everything out for us, but if you want to know the why's and how's this is the best article I have ever read on the subject:
