Description

Fuel, Exhaust & Emissions, Systems Cleaner: 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 the exhaust system. These along with other active chemical agents, react with the gases created in the combustion process to remove the remaining inorganic deposits. This process restores their function and with regular use maintains efficiency. As fuel is burned contaminating byproducts are created that get circulated throughout various vehicle components. The system is 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 greatly increase the amount of contamination and deposits created inside these systems. Such factors 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.

    • Helped pass SMOG CHECK.
Style: 1-pack
A code for my cat converter came up and a mechanic recommended a whole new cat, pricey. A friend of my dad who used this product to help older trucks pass emissions recommended this cleaner for our problem. I bought 3 bottles for a deep cleaning as instructed and used the last before emissions testing. Check Engine light was off (Colorado SMOG CHECK must have check engine light off) and passed SMOG Check comfortably. Helped keep my 05 Nissan Armada running for another two years. Worked for code we checked. ... show more

    • Does not work P0420 check engine code
Style: 1-pack
I bought two of these because I figured they would work. It says that it would get rid of the check engine light and fix P0420 code. Well it did neither. My car is almost at 300,000 miles and I have a P0420 error code. I added one of these to the fuel system. I reset my check engine light and prayed for the best. It was about 100 miles when my check engine light came on again. I just figured that it was starting to work, so I decided to put another one in. These aren't cheap by the way. I reset my check engine light again. And again about the 100 mile mark, my check engine light came on again. I gave up on this product and I will never buy it again. ... show more

    • Did exactly what it claims
Style: 3-pack
My older Audi needs the primary ports cleaned. This is around $3800 to perform this service. I was skeptical in purchasing this cleaner. Simple to use and did the trick! My check engine light went out, car runs better and now it is part of my quarterly maintenance!

    • Wow, Cleared my clogged 4-CAT System in less than 10 Miles!
Style: 1-pack
I spent $0 on CatClean and it did nothing. Drove with the clogged cat code for about 2 weeks after using the CatClean and code never disappeared. I looked on Amazon for reviews for a better product and this one seemed to have the happiest customers, so did it just as others stated. I filled my empty tank to half-full of Chevron Premium gas, poured in the bottle, made a few stops around town, turning off my car when parked, and in less than 5 miles in town driving the code turned off! I should ad that I have a Nissan Frontier with FOUR catalytic converters, so this bottle did a lot to save me time and money. So, whatever is in this bottle, I am so far thousands of dollars happier that I don't have to buy one or maybe four new converters. IS THIS JUST RELEASING ALL THE SMOG THESE ARE DESIGNED NOT TO LET OUT IN THE ATMOSPHERE. For those people who are sharing their belief that this is what happens when you use a product like this: DO YOUR HOMEWORK! If you research, you will find that a Catalytic Converter isnot a smog filter. It's a carbon converter that takes the unburned fuel carbon and exhaust that your car is passing throguh the engine and "converts" it into harmless gases that do not hurt the atmosphere. So, this product seems a lot better to keep using periodically so you converter is actually clean most of the time and doing its job. ... show more

    • P0420 CEL Clear
Style: 1-pack
Kept resetting P0420 CEL on my 2007 Toyota Corolla, hoping I could quickly go through drive cycle and pass my smog check before it came back on. Same code kept coming back on within 2-3 miles of a reset so using Rislone was my last hope before I tried the non fouler trick. Below is exactly what I did, hope it helps someone! 1) Filled my gas tank with premium gas, drove it down to half tank over a few days of driving before I inserted Rislone. 2) Drove ~30 miles and then refueled to full tank with premium gas again(Half highway/half city as instructions state) 3) Instructions say after completing step 2, drive the car to 1/4 gas tank at which point CEL should clear. For me, I drove ~25-30 miles over 3 days, clearing the CEL each time it came back on. During the 3rd day (~60 miles since using Rislone), the CEL didn’t come back on and all monitors reset! Immediately went to smog station and passed. CEL is still off, not sure it will last but who cares! Car is running fine and I don’t need to pay for a new converter just to pass a smog test! Tips: 1) Not sure if premium gas made a difference but I read several people say they used non ethanol/premium gas which cleared P0420 so figured it couldn’t hurt. 2) I bought a cheap OB2 monitor which I kept on when driving so I could see exactly when CEL was coming back on and when monitors are smog ready. If you’re lucky, resetting CEL and going thru drive cycle may be enough to get past smog without using Rislone. In my case, the P0420 CEL would come on within 2-3 miles each time I reset the CEL so using Rislone was a must. 3) Each car is different but generally speaking, once you reset CEL the drive cycle consists of warming up the car for a few minutes and driving 50-60 mph a few times, ideally letting the car come to a stop with no or minimal use of the brake. Make sure A/C is off. Using the OB2 monitor while driving the car will help you get a feel for your cars drive cycle. 4) If a CEL code is pending, the relative monitor to your code will not clear! In California, all monitors except EVAP have to be ready to pass smog, your state may be different. ... show more
