MotorPower Care Catalytic Converter Cleaner for Gas & Hybrid Engines — 8.45 fl oz, TÜV-certified O2 Sensor & EGR treatment

This concentrated German-formula treatment is made for gasoline and hybrid engines and designed to be poured directly into the fuel tank. It works during normal operation to soften and carry away deposits that restrict exhaust flow and interfere with sensor readings, helping restore smoother combustion and lower emissions. The product is TÜV-certified and intended for periodic preventive use every ~3,000 miles or when emissions-related codes appear.

How do I use MotorPower Care to treat my catalytic converter?

Pour the entire bottle into the fuel tank and mix with 5–15 gallons (recommended mixing ratio ~1:300). Run the engine and drive for about 40 minutes, using short wide-open-throttle accelerations every 10 minutes on safe, open roads to help flush deposits through the exhaust while the formula is active.

• Add one 8.45 fl oz bottle to 7–12 gallons of gasoline for best coverage.
• Drive continuously for 40 minutes after treatment; accelerate briefly every 10 minutes.
• Works while the engine runs—no disassembly or special tools required.
• Inspect the catalytic converter via the O2 sensor port before use; don't apply if the converter is cracked or melted.

Will this fix a P0420 or P0430 check-engine code?

This cleaner targets carbon and soot that commonly cause inefficient catalyst readings and O2 sensor errors. Many users clear P0420/P0430 codes when deposits are the root cause, although physical damage to the catalyst cannot be reversed by a liquid treatment.

• Dissolves deposits on catalyst substrate and oxygen sensors that skew readings.
• May resolve emissions codes caused by fouling rather than mechanical failure.
• If the converter is cracked, melted, or physically damaged, replacement is necessary.
• For very clogged units, pair with the direct foam cleaner (SKU 8101) for more aggressive cleaning.

What emissions and performance benefits should I expect?

The formula is designed to reduce common exhaust pollutants by improving catalyst efficiency and restoring accurate sensor signals. While results vary by vehicle condition, lab and field testing show notable reductions in hydrocarbons and NOx when deposits are the primary issue.

• Can lower HC, NOx, and other emissions tied to poor catalyst performance.
• Helps oxygen sensors and EGR systems read correctly for improved engine control.
• May improve fuel efficiency and smooth engine operation by clearing flow restrictions.
• Recommended as a preventive treatment every ~3,000 miles to maintain exhaust cleanliness.

Is MotorPower Care safe for my engine and fuel system?

The product is formulated for compatibility with all gasoline and hybrid engines and is TÜV-certified, indicating it meets strict performance and safety benchmarks. It is intended for in-tank application and is not a substitute for mechanical repairs when hardware is broken or severely damaged.

• Safe for catalytic converters, oxygen sensors, fuel injectors and EGR valves when used as directed.
• Do not use if the converter shows visible cracks or severe structural damage.
• Routine use helps prevent costly replacement expenses associated with neglected deposits.
• Made in Germany with quality controls and government-tested emissions data available.

Who is this for: MotorPower Care Catalytic Converter Cleaner suits vehicle owners, DIY mechanics, and fleet operators who want a simple, in-tank treatment to tackle emissions-related fouling and restore exhaust-system function without immediate shop labor. It's especially useful for drivers facing marginal smog test results, recurring P0420/P0430 codes, or periodic maintenance plans for gasoline and hybrid vehicles. For converters that are damaged or heavily degraded, professional inspection and hardware repair or replacement remain the correct course of action.
