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.
I used the Rislone 4720 cleaner in my older car and definitely noticed an improvement in emissions. The 16.9 oz bottle was enough for a full treatment and my check engine light hasn’t come back since! Feels good to help the environment a bit with my ride.

Easy to use and effective!
I added the Rislone 4720 to my gas tank, and I was surprised at how easy it was. My car runs smoother, and I noticed a drop in emissions during the last inspection. Perfect size for a quick treatment!

Mixed feelings about effectiveness
I tried the Rislone 4720 cleaner as a last resort for my emission issues. It did help a bit, but I wasn't blown away. My exhaust still smells a little off, but the emissions did seem slightly lower. Maybe it needs more time?

Good value for money
I was skeptical about the Rislone fuel cleaner at first, but it really did help clean my catalytic converter. The 16.9 oz size is convenient, and it came at a reasonable price. Just wish it had instructions for how often to use it!

Disappointed with the results
Unfortunately, the Rislone cleaner didn’t work for my car. I followed all the instructions, but it didn’t seem to have any real effect on the engine performance or emissions. I expected more for the price I paid.
