About Catalytic Converters:

As fuel is burned contaminating pollution is created that is circulated throughout various vehicle components. The system is designed to be able to handle this during most normal engine operation. The use of poor quality fuel, short driving distance, cold weather, improper maintenance, and component failure can greatly increase the amount of contamination and deposits created inside these systems. This can cause increased exhaust emissions, reduced fuel economy, lost power & performance, drivability issues, engine overheating, hard starts, check engine light illumination and premature engine wear.

Affordable Innovation for Common Problems

Introducing Rislone Cat Complete Fuel, Exhaust & Emission System Cleaner – the most advanced catalytic converter and emissions product available anywhere.

This formula is engineered to help you clean dirty catalytic converters, clear common OBD check engine light (CEL) codes, pass emissions testing and improve the overall health and performance of your fuel system.

Cat Complete Fuel, Exhaust & Emissions System Cleaner has high-performing detergents and heavy-duty cleaning solvents that effectively scrub and remove contaminants, soot, carbon build-up, and oily residue from the fuel injectors, combustion chambers, turbo, EGR, catalytic converters, oxygen sensors and exhaust. This, along with other active chemical ingredients, react with the gases created in the combustion process to remove the remaining inorganic deposits. This restores lost function, and with regular use, maintains efficiency.

The use of poor quality fuel, short driving distance, cold weather, improper maintenance, and component failure can greatly increase the amount of contamination and deposits created inside these systems. This can cause increased exhaust emissions, reduced fuel economy, lost power & performance, drivability issues, engine overheating, hard starts, check engine light illumination and premature engine wear.

Other benefits of Cat Complete Fuel, Exhaust & Emission System Cleaner are:

  • Cleans fuel and exhaust system – reduces excess exhaust hydrocarbon, CO and NO X emissions and saves gas.
  • Contains outstanding synthetic detergents to remove IVD intake valve deposits, CCD combustion chamber deposits and other fuel deposits.
  • Includes combustion catalyst for improved gas mileage, smoother idling, drivability and better throttle response.
  • Reduces zinc and phosphorus catalyst contamination, restoring catalytic converter function.
  • Cleans O2 Lambda oxygen sensor tip.
  • Clears OBD-II PID CODES: P0138 P0139 P0143 P0144 P0145 P0146 P0151 P0152 P0153 P0154 P0157 P0158 P0159 P0160 P0163 P0164 P0165 P0166 P0171 P0173 P0174 P0175 P0420 P0421 P0430 P0431.
