## Overview

Rislone Cat Complete Fuel, Exhaust & Emissions System Cleaner is a powerful 4-pack treatment designed to clean fuel injectors, combustion chambers, exhaust systems, and emissions components. Compatible with a wide range of engines including hybrids and turbocharged models, it boosts fuel economy, restores engine performance, prevents check engine light alerts, and meets EPA standards without voiding warranties.

## 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.
