Am I killing the catalytic converter? 900

I just came from an emission test here in Ontario and the car passed, but my hydrocarbon reading was six times as high as last time, the carbon monoxide was twice as high as last time, and my nitrogen oxides were down by more than a half. I switched to Mobil 1 in between the last test and this one. There is nothing wrong with the car, same power as always, no black smoke, no leaks. The technician who did the test let it idle for about 10 min. so I am going to do the test again to verify the numbers.

The engine is consuming Mobil 1 as initially expected, but I wander if the high hydrocarbon reading is an indication that I am killing cat with Mobil 1. Any thoughts?
