which oil for summer/autox days...

I've read some threads on here and everyone seems to be using Mobil1 0w40 for DD...

Im wondering what you trackers/auto-x'ers are running...
Which would you choose Mobil1 or Royal Purple 0w40 or 10w40 FOR TRACK/AUTOX days??

**Wouldnt the 0w40 be too thin for track days??
btw I have oil cooler


Thanks

I'm using Mobil 1 5W-30, but only because I get it for free. If I were to pay for it I'd probably buy some 0W-40. I don't have any issues with heat at the autoX, but I don't think you would with any oil with 1 minute runs.
