I believe they just recommend 15w-50 for track only, because of higher cold start wear and tear. The thick oil needs more time to lubricate the cold engine.

I did run last week fresh 0W40 at the track. Oil temp went up to 290°F. Lateral G forces were between 1.2-1.4. I got the OEM 1LE Aero on my ZL1.
What you guys think about the Mobil 1 FS X2 5W50? To my understanding it should work perfectly for street and track use. I probably use it next time at Track and for street use. The 15W50 isn't available for me.
