The bad is the carbon gunk and other mess cleaned from the cylinders clogged my catalytic converter and covered my oxygen sensor, leading me to purchase a cleaning fluid remedy for that. Otherwise highly recommended. I have a 2012 Ford Escape with 127K miles.

I'm in the process of testing this product in a 2015 Subaru Impreza but so far I've seen slight improvements with gas mileage and move offs with stop and go traffic, also a rough spot that would appear during idling is basically gone.
