These along with other active chemical agents, react with the gases created in the combustion process to remove the remaining inorganic deposits.

Worth a try!

10 hours ago
[This review was collected as part of a promotion.] I tried Rislone Cat Complete Fuel, Exhaust & Emissions System Cleaner after my car started running rough and the check engine light came on for an emissions issue. I added it to a near-empty tank and filled up with gas as instructed. Within about 100 miles, I noticed smoother acceleration, better throttle response, and the check engine light turned off. It was easy to use and seemed to make a real difference. I know it’s not a fix for a damaged catalytic converter, but it definitely helped clear up buildup and improve performance. I plan to use it again as part of my regular maintenance.

Yes, I recommend this product.
