Question:
What is Rislone 4720 Cat Complete Fuel, Exhaust and Emissions System Cleaner used for?
Answer: Rislone 4720 is designed to clean the catalytic converter, exhaust systems, and fuel systems of your vehicle. This means it helps to break down and remove carbon deposits, which can cause your vehicle to perform poorly. By optimizing airflow and exhaust systems, it effectively reduces harmful emissions and can even help improve fuel efficiency. For best results, consider using it regularly or as a preventive measure to maintain vehicle performance. -
Question:
How does Rislone 4720 help in reducing emissions?
Answer: Rislone 4720 functions by cleaning the catalytic converter and exhaust systems, reducing the build-up of harmful deposits. This ensures that your engine runs cleaner, reducing the amount of unburned fuel and toxins that are expelled into the environment. In effect, using this cleaner can lead to a notable drop in your vehicle's emissions, contributing to a healthier environment while also helping your vehicle meet regulatory standards. -

Many users report improved performance without harming their engine components. Just ensure to follow the instructions for use as outlined on the product label for optimal results. -
Question:
How often should I use Rislone 4720 in my vehicle?
Answer: It is generally recommended to use Rislone 4720 every 3,000 to 5,000 miles, or during every oil change, depending on your driving conditions. This helps in maintaining the cleanliness of your fuel and exhaust systems. If you notice that your vehicle is experiencing reduced power or increased emissions, a treatment at that time may be beneficial for restoring performance. -
Question:
Will Rislone 4720 improve my car’s fuel economy?
Answer: Rislone 4720 can help improve fuel economy by optimizing the combustion process and ensuring your fuel system is clean. A clean catalytic converter facilitates better airflow and combustion efficiency, which can lead to lower fuel consumption over time. If your vehicle is seeing a decline in miles per gallon, using this cleaner may be an effective solution to help enhance its fuel efficiency under normal driving conditions. -
Question:
What are the main ingredients in Rislone 4720?
Answer: Rislone 4720 contains a blend of detergents and ignition improvers that are specifically formulated to clean and restore the fuel, exhaust, and emissions systems.

This unique formulation is designed to prevent future build-up, ensuring long-term engine performance. -
Question:
Can Rislone 4720 clean a clogged catalytic converter?
Answer: Rislone 4720 can assist in cleaning light to moderately clogged catalytic converters by breaking down carbon deposits and restoring performance. While it may not resolve severe blockages, it can help in the recovery of efficiency when used regularly. If you suspect severe clogging, it's advisable to seek professional assistance alongside using Rislone for optimal outcomes. -
Question:
Is Rislone 4720 a standalone product or part of a regular maintenance routine?
Answer: While Rislone 4720 is effective as a standalone product for cleaning emissions systems, it works best when integrated into a regular maintenance routine. Combining it with routine oil changes and fuel system cleaners can optimize your vehicle's performance. For car owners who are keen on maintaining long-term vehicle health, using Rislone alongside other recommended products ensures comprehensive care. -
Question:
Does Rislone 4720 have any detrimental effects on engine components?
Answer: No, Rislone 4720 is specifically formulated to be safe for all engine components. It does not contain harmful solvents that can degrade rubber or other materials found in your engine. Vehicles treated with Rislone often report improved performance and longevity, with no adverse effects noted. When used as directed, it enhances rather than harms engine health. -

Rislone Fuel System Cleaners Editorial Review
The Rislone Cat Complete Fuel, Exhaust and Emissions System Cleaner is a product that aims to clean the catalytic converter and related systems, helping to turn off the check engine light and improve fuel efficiency. According to the brand, it can also help pass state emissions testing. The product is easy to use - simply pour the entire bottle into the gas tank and drive for 20 to 30 miles before refuelling. Customers have reported mixed experiences with the product. Some have found it to be effective, turning off their check engine light and increasing fuel efficiency. Others, however, have reported that the product did not work for them, and they were disappointed with the money-back guarantee, which required information from the box and a professional report with the code. Overall, it seems that the Rislone Cat Complete Fuel, Exhaust and Emissions System Cleaner may work for some, but not for others. If you're experiencing issues with your emissions system, it may be worth giving this product a try, but be aware that it may not be a permanent solution.
