The big key to running the heavy 15w50 for track is to MAKE SURE you warm it up before getting in the throttle. Otherwise you can collapse the filter.

I run with Mobil 1 15-50 for track and street. It doesn't get cold here so I don't worry about winter temps. Probably in your area you would want to change to a lower viscosity for winter street driving.

5-40 for winter, 15-50 for the hot hot heat.

Great topic, I just went through this question yesterday looking for oil.
