Product Details
Buying Cataclean in a 3-pack makes sense if you plan to follow the recommended quarterly maintenance schedule, giving you enough for most of a year of treatments. Each 16 oz bottle is the same EPA-approved formula that cleans your catalytic converter, oxygen sensors, fuel injectors, and cylinder heads by reducing carbon buildup throughout the fuel and exhaust system.
Cataclean has been tested at independent emissions facilities and shown to lower total hydrocarbon emissions by up to 50 percent, which makes it a practical option before an emissions test or as regular maintenance. The formula does not alter fuel composition and is safe for catalytic converters and oxygen sensors. To use it, pour one full bottle into roughly a quarter tank of fuel and drive for at least 15 minutes, then refuel when needed.
Each bottle works in one treatment, so this 3-pack covers three separate applications. Cataclean is legal in all 50 states and works in gasoline engines. For vehicles with capless fuel systems, use the manufacturer-supplied funnel when pouring.
