Yes. It’ll clog the converter. The oil will burn in the converter and destroy the converter. An Actron CP9690 checks codes and has code-connect to diagnose codes. It shows top solutions to codes. I/M monitor test shows systems that will fail the smog test. South Main Auto and Astral Auto demonstrated the CP9690. EBAY has it.
1) This thing burns oil at an inconsistent rate, but averages 1 qt per 400-600 miles using 0w-20. Thinking about switching to 5w-20 at the next oil change. 2) I believe the burning oil is causing a P0420 (Catalyst system efficiency below threshold (bank1). The oil has to go somewhere and it’s probably somewhere in the exhaust.
Catalytic Converter & Burning Oil? – Bob Is The Oil Guy

The rattling is caused by the cat coming apart inside, which doesn’t have anything to do with the oil consumption. I’d say your rate of oil consumption might shorten the cat life a bit, depending on when the engine’s oil consumption is the …
The oil that’s burned in the engine ends up flowing through the exhaust system, where it can eventually cause catalytic converter failure in much the same way as a coolant leak. Black smoke or signs that your car is using a significant amount of oil in between changes are indicators that you may end up reducing the efficiency of — or even permanently damaging — …

What causes a catalytic converter to go bad?
It can also be due to any number of small design issues or worn-out engine components. The oil that’s burned in the engine ends up flowing through the exhaust system, where it can eventually cause catalytic converter failure in much the same way as a coolant leak.
Where is the catalytic converter located in a car?
Your vehicle’s catalytic converter sits ahead of the muffler in its exhaust system. It’s a small, oval-shaped chamber packed with materials such as platinum and/or palladium in a honeycomb-type design.
What happens when you put unburned fuel in an engine?
Engine exhaust is already quite hot, so when you add in a contaminant like unburned fuel, which can find its way into the exhaust system when your motor is running too rich, you compound the effect, as that fuel typically ends up burning inside the converter itself.
