I haven't personally used it, but I'd recommend a long drive on the highway to really heat up everything to burn up and pass anything that might've collected in the catalytic converter.
What happened in the engine that resulted in build up in the cat?
Took it for a rattle I could not find. Sounded like a loose heat shield. Maybe I am being gamed?
If you're diagnosing a rattle, no snake oil in a can is going to help most likely, unless the rattle you hear is the honeycomb of the insides of the conveter. if it's from the interior of the cat, you're going to need a new catalytic converter, and your engine will most likely realize something is wrong from the readings on the downstream
02 sensor.Do you live and drive somewhere where they use salt on the roads in the winter? If so, I'd figure it's the heatshield breaking loose due to rust. Hard to say for sure without seeing the cat, but more than likely the heatshield could be ripped off the resolve the rattle and you can truck on.
I forgot a line, are you currently getting a check engine light or anything of the sort on the dash of the Juke?
I would have stopped with that, or just not going to help period. I'd be skeptical that any additive is going to fix a catalytic converter period. Some people think a cat failure is like the worst thing ever. I have a friend who had a Honda CRV, the cat light would come on after long drives. He got it through inspection once after that, next time he was obsessed with the cat problem. I told him he could reset the light, wait for the monitors to be set and likely get it through state inspection before the light came on again. I looked up the cost of a new cat, it was around $300, which I told him. Instead he went to the dealer for an oil change and decided to buy a new car. They gave him $1000 for his Honda CRV that was in decent condition, easily worth 3 times that or more..... Go figure.
The issue is usually the sensor and not the cleaner itself. Lots of stuff on line like this:
It's a Nissan - 'nough said. Between Nissan and Mitsu for the worst new cars available in Canada / USA. Possibly throw the recent crop of Luxury (and other) German cars into the mix as well - - -

The proverbial race to the bottom.
I can understand it for the cheap shitboxes but for luxury vehicles? They used to throw their best people at them to boost the name. The tech and features would would itself down to the less models. I hypothesize that management is brought in from outside that has no familiarity with auto design and manufacturing. The short term shareholder dividend is king and longterm thinking fell out the trunk.
My thinking has always been: they would rather spend 2 bux to put a flashy emblem on the dash than to spend 25 cents in putting a proper seal that lasts.
Clare, what are your thoughts?
Particularly true with Nissan / Renault / Mitsishitty. Mazda, BMW and Mercedes following fast in their footsteps.
Ford, Fica (at least the Chrysler portion) and GM are run pretty much by accountants to benefit the hedge funds that provide the financing through the stock market. How many years did GM profuce the 3800 with the self-destructing intake manifold (that got burned by the EGR tube)? and the ignition switch that shut off if you had 4 or 5 keys on your key-ring? The accountants figured it was cheaper to pay warranty claims, and more effective to pray most of them made it off warranty than to spend what it would have taken to actually solve the problem. Even pay a few death benefits if a few customers died.
I think GM has been the worst among the "big 3" for that. Toyota and Honda have had a few situations along with Hyundai / Kia but nothing on the scale of the Big 3, Nissan et al, and the Germans.
