It gives some peace of mind knowing the oil pressures are better than with a 0w-20 if I'm intending to track the car. I've seen the oil pressure drop very low into the single digits (psi) during idle after running the engine slightly hotter than normal using 0w-20. The better solution would be an oil cooler. As far as being strictly street driven during the winter time I wouldn't see a need to run thicker oil. Even if you like to punch it to redline now and again. If you're not seeing much sustained high temp operation I really see no need.
