So should the ZL1LE use 15w50 all of the time or 0w40 off track and 15w50 on track?

I agree it's getting confusing. All the promotional material I've seen from GM regarding this oil claims it has the advantage that it can be used for street and track. No more need to change to a different viscosity oil for track use. The only exception is the LT5 in the ZR1. A heavier weight oil is still recommended for track use.
