Redline would be a bad choice for extended OCI's: great product for shear stability but not the best add pack even on their street synthetics (not talking about their pure race products...which is race only really).

For a street oil, Pennzoil Ultra is also an excellent product and their 5/30 has been showing very good UOAs on our Z (PA, 90+deg humid summer days) and I wouldn't hesitate to run that at a track event either.
