Cataclean Fuel & Exhaust System Cleaner for Gasoline Engines — 16 oz Bottles, 6-Pack | Removes Carbon, Lowers Emissions

Cataclean Fuel & Exhaust System Cleaner is an add-in bottle that cleans fuel injectors, catalytic converters and exhaust components to improve combustion, reduce carbon buildup and help lower emissions.

This 16 oz formula, sold here as a convenient six-pack, is designed for routine vehicle maintenance. It mixes directly with gasoline and treats the fuel and exhaust pathways to remove deposits that hinder performance. The product is positioned to help vehicles run more efficiently and may address common engine codes associated with emissions and combustion issues.

How will Cataclean affect my car's fuel economy and drivability?

Using Cataclean helps strip carbon and varnish from fuel injectors, intake ports and combustion chambers, which can restore smoother fuel flow and more complete combustion. Drivers often notice steadier acceleration and a return of lost power after treatment.

• Restores injector spray patterns for improved fuel atomization.
• Reduces rough idling and hesitation during acceleration.
• Can improve miles per gallon by optimizing combustion.

Can this cleaner help with emissions or a check engine light?

Cataclean targets carbon buildup in key emissions components such as catalytic converters and oxygen sensors, which can contribute to elevated hydrocarbon output. Treating these deposits can help resolve codes tied to inefficient combustion and catalytic converter performance.

• Formulated to lower hydrocarbon emissions on gasoline engines.
• May address common trouble codes related to exhaust efficiency.
• Supports catalytic converter function without removing parts.

How do I use Cataclean and how often should I add it?

Application is simple: pour the bottle into the fuel tank before filling with gasoline, following the directions on the label for tank size. Regular scheduled use keeps deposits from reaccumulating and fits easily into routine maintenance.

• One 16 oz bottle treats a full tank per label instructions.
• No tools or mechanic required—add directly to fuel tank.
• Recommended intervals are listed on packaging for sustained benefits.

Is Cataclean compatible with my vehicle type and state regulations?

Cataclean is formulated for gasoline engines and is compatible with many modern vehicle platforms, including hybrids. The product is marketed as compliant for use across all 50 states.

• Safe for use in gasoline and many hybrid systems.
• Marketed as 50-state legal for emissions-related applications.
• Designed to work without altering factory emissions hardware.

Who is this for: Cataclean Fuel & Exhaust System Cleaner is aimed at drivers who want a simple, do-it-yourself way to reduce carbon deposits, potentially improve fuel economy and support their vehicle's emissions systems. It is a practical option for owners of gasoline-powered cars and light trucks who prefer preventative upkeep and wish to address performance quirks before pursuing more costly repairs.
