Yes, many times it can, especially if you catch it early and it is not completely blocked.
P/N 4720 / 16.9-ounce bottle – One full bottle is used to treat normal passenger and light truck vehicles.
Yes, instructions must be followed to receive the best results. Add entire bottle of CAT COMPLETE™ Fuel, Exhaust & Emissions Systems Cleaner into approximately 1/2 full tank car (1/4 full tank truck) of gasoline. Drive vehicle 20 to 30 miles (ideally half of these miles at highway speeds) and then fill up tank. Continue to drive vehicle normally until below 1/4 tank before refueling. Take emissions test at this time (if needed) and CEL light should be off. Depending on the severity and length of time light has been on, it may take an extra 250 miles with multiple cycles of the vehicle being started and turned off for the light to reset. If light is still on mechanical attention is needed.
Regular use every 5,000 miles tunes-up the fuel, emissions and exhaust systems, keeping them clean and preventing the CEL light from returning. This also saves on expensive fuel system and emission control repairs.
Yes, Rislone CAT COMPLETE Fuel, Exhaust & Emissions System Cleaner works with all regular unleaded, premium, oxygenated, and E10 E15 E85 ethanol containing flex fuels.
As fuel is burned, contaminating byproducts are created that get circulated throughout various vehicle components. These systems are designed to be able to handle this process during most normal engine operation. However, the use of poor-quality fuel, short driving distance, cold weather, improper maintenance, and component failure can create and greatly increase the amount of contamination and deposits inside these systems.
The catalytic converter, sometimes called the catalyst or “cat”, is an emission control device mounted in the vehicle exhaust system that contains a catalyst which converts toxic pollutant gases into less harmful gases. A motor vehicle can have one or more of these. There are multiple designs including honeycombed and bead shape, which are coated with precious metals like palladium, rhodium and platinum.
Vehicle manufactures say that the catalytic converter should last the life of the vehicle, but in the real world this is usually not the case. Many things can cause the converter to go bad or fail, but in most of these cases it was not the fault of the converter itself, it was something else which poisoned or ruined the converter. Some examples would be a bad head gasket where coolant enters the exhaust, poor piston rings causing the engine to burn oil, dirty fuel injectors, clogged fuel filter and even driving many short trips can shorten the life of the converter, among many others.
A poison to the catalytic converter or oxygen sensor is any substance that coats its surface and no longer allows it to react with the exhaust gasses. Lead, which used to be in gasoline, was the number one poisoning substance, and one of the reasons it has been removed from fuels. Zinc and phosphorus in engine oils are other potentially damaging substances, especially if the vehicle is burning oil. Burned engine coolant (ethylene glycol) is also bad, which happens when a head gasket fails. Silicone, commonly found in gasket sealants, have also been known to harm catalytic converters.
Because of the increased backpressure that builds up from a clogged catalytic converter, the vehicle will have drivability issues like low power and performance, reduced fuel economy, hard starting, stalling, increased emissions and check engine light illumination.
No, this will not harm your engine or any emissions components. This product is specifically designed to be safe to use on vehicles which have oxygen sensors and catalytic converters. Likewise, it will not void manufacturer’s new vehicle warranty. Exceeds EPA compliance performance criteria.
Yes, this can help with multiple causes of the strong sulfur (rotten egg) smell relating to an incorrectly functioning catalytic converter or some of the fuel system problems that contribute to this issue.
Using a product like Rislone Fuel, Exhaust & Emissions System Cleaner should be the first step before replacing the catalytic converter. This not only gives the vehicle the best chance of being repaired affordably, but also works to fix a contributing issue which may have caused the problem with the converter.
The number one check engine light code is P0420 – It has sister related codes which are P0421, P0430 and P0431. These codes mean that the efficiency of the catalytic converter is below its functional threshold.
Yes, this multi-vehicle formula works with all fuel injected, port fuel injection (PFI), direct injected (DI / DIG), gasoline turbo direct injected (GTDI), turbocharged and carbureted engines.
Yes, this is safe to use and works in all domestic and import turbo charged and directed injected gasoline (GDI) engines like the Ford EcoBoost, GM Ecotec and all others.
Many factors can cause this including something as simple as a loose or missing gas cap. Other common items are a bad or clogged catalytic converter, damaged or dirty oxygen sensor, failed ignition coil/spark plugs/wires, dirty mass air flow (MAF) sensor, bad EVAP purge control valve, clogged fuel injectors.
Many retail auto parts stores offer free on-board diagnostic (OBD) code checks, and inexpensive code readers are available to purchase for do it yourself (DIY) checks.
When the check engine light (CEL) or malfunction indicator light (MIL) illuminates, it has detected an engine system malfunction.
Many states or regions require regular emissions inspections before renewing vehicle plates or the first time registering. During a visual inspection if there are missing or tampered emissions components, that can be an automatic failure. It also could be something simple like a missing gas cap or a cap with a bad seal. Defective mechanical parts that have failed would be another reason. Many times, it does not take a mechanical issue to cause a failed result on a vehicle emissions test. If you are unsure your vehicle will pass, or maybe it barely passed the last test, we recommend a fresh oil change and emissions system cleaning with Rislone Fuel, Exhaust & Emissions System Cleaner before testing. Other items to consider include spark plugs and fuel filter, if they are due for replacement. This gives your vehicle the best chance of passing.
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.
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.
Other benefits of Cat Complete Fuel, Exhaust & Emission System Cleaner are:
If you are struggling with a persistent Check Engine Light (CEL) due to a dirty catalytic cleaner, poor gas mileage and throttle response, or passing a state-mandated emissions test, Rislone Cat Complete Fuel, Exhaust & Emission System Cleaner is a simple, effective and affordable solution that anyone can install – no special expertise needed.
