P0420 code after Protect and Restore

[rvsarch]

All emission readiness tests have completed including catalytic converter, which cleared the permanent P0420 code. The pending and confirmed P0420 codes have not come back since they were erased. I'll probably use Cataclean again right before a planned trip to Maine. Since my wife drives so many short trips with the car, I'm going to use it once a week for a highway trip I normally make in my car, a 2007 Accord V-6 manual 6 speed coupe which consumes no oil. Going to try 5w30 Restore and Protect in the TSX to see if oil consumption decreases over the summer. VTEC actuator on the TSX can rattle on startup when the temps are in the low 20's, so I'll probably run 0w20 in the winter.
