I don't believe the 2 ounces I added will have an effect on the catalytic converter.
Additionally, it is my understanding that as part of the emissions package, the CATS are covered by the emissions warranty, 8 years/80,000 miles.
By the way, we just chased the car to North Carolina and Virginia. There are now well over 2000 miles on her since adding the 2 ounces of Redline, and she continues to purr silently.
Unless I can be convinced otherwise, based on these results I intend to continue to add 2 ounces to the crankcase immediately after every oil change going forward.
