Boost Up Catalytic Converter Cleaner: A Powerful Solution for Emission System Maintenance GuideMechanic.Com A catalytic converter plays a vital role in your vehicle’s emissions control system. Its job is to convert harmful pollutants in exhaust gases into less harmful emissions before they exit the tailpipe.
However, over time, carbon buildup, oil residues, and unburned fuel can clog the converter, leading to reduced performance, higher emissions, and Check Engine Lights—especially P0420 or P0430 codes.
This is where Boost Up Catalytic Converter Cleaner comes into play. Designed to clean the entire exhaust and fuel system, this product has gained popularity among car owners seeking a cost-effective, easy-to-use alternative to expensive catalytic converter replacements.
In this article, we’ll explore everything you need to know about Boost Up Catalytic Converter Cleaner: what it is, how it works, how to use it, and whether it really lives up to the hype.

What Is Boost Up Catalytic Converter Cleaner?
Boost Up Catalytic Converter Cleaner is a specially formulated fuel additive that helps clean the emissions system in gasoline and hybrid vehicles. Its primary targets are:
- Catalytic converters
- Oxygen (O2) and lambda sensors
- Fuel injectors
- Combustion chambers
By breaking down and removing carbon deposits and other harmful build-ups, Boost Up helps restore engine performance, improve fuel efficiency, and reduce emissions.
Many users turn to this product when their car shows symptoms of a clogged catalytic converter, or as a preventive measure to avoid future issues.
How Does It Work?
Boost Up is added directly into the fuel tank, where it blends with gasoline. As the engine runs, the additive passes through the fuel injectors, intake valves, combustion chamber, and eventually into the exhaust system. Here’s how it works at each stage:
- Cleans Fuel System – It removes dirt, varnish, and carbon from fuel injectors, helping achieve cleaner combustion.
- Improves Combustion Efficiency – Clean combustion reduces the number of unburned hydrocarbons entering the catalytic converter.
- Breaks Down Carbon Buildup – As the treated fuel burns, the cleaner heats up and reacts with deposits in the converter and O2 sensors, helping remove them over time.
- Reduces Emissions – With cleaner exhaust flow, the engine can operate more efficiently and emit fewer pollutants.
The end result is a cleaner, more responsive engine and a healthier catalytic converter.
Key Benefits of Boost Up Catalytic Converter Cleaner
✅ Clears Emissions-Related Trouble Codes
Many car owners use Boost Up after receiving a P0420 error code, which typically indicates low catalyst efficiency. While not guaranteed, a cleaner converter has the potential to resolve such codes without costly repairs.
✅ Helps Pass Emissions Tests
If your vehicle has failed an emissions test or is due for inspection, Boost Up can help reduce NOx, CO, and hydrocarbon emissions.
✅ Prevents Converter Damage
Regular use can help prevent expensive catalytic converter replacements by keeping the converter clean and operational.
✅ Improves Fuel Economy
By cleaning fuel injectors and the combustion chamber, Boost Up can help restore lost MPG and engine responsiveness.
✅ Works in Most Gasoline Engines
It’s suitable for use in:
- Gasoline engines (carbureted and fuel-injected)
- Hybrid vehicles
- Turbocharged engines
- Vehicles with OBD2 systems
Symptoms That Indicate You Need a Catalytic Converter Cleaner
Here are some signs your vehicle might benefit from a treatment with Boost Up:
- Check Engine Light (CEL) is on with a P0420/P0430 code
- Poor fuel economy
- Engine hesitation or reduced power
- Sulfur or rotten egg smell from the exhaust
- Failed emissions or smog test
- Rough idling or misfires
Using Boost Up before these issues get worse can be a smart and affordable step.
How to Use
Using Boost Up is simple and doesn’t require any mechanical skill. Here’s a step-by-step guide:
- Step 1: Prepare Your Vehicle
Ensure your fuel tank is at least ¼ full, but preferably between ¼ and ½ full.
Warmer temperatures and longer drives help the cleaner work better.
- Step 2: Add Boost Up to Fuel Tank
Shake the bottle well.
Pour the entire contents into the gas tank.
One bottle treats up to 15–20 gallons (approx. 60–75 liters) of fuel.
- Step 3: Drive Normally
Drive your vehicle as you usually would.
For best results, take it on a longer highway drive to get the exhaust system hot enough to activate the cleaner effectively.
- Step 4: Monitor the Results
Improvements in engine performance, fuel economy, and exhaust smell are often noticed within a single tank.
If you’re dealing with a CEL or error code, use an OBD2 scanner to see if it clears after the treatment.
How Often Should You Use It?
- Maintenance Use: Every 3,000 to 5,000 miles
- Before Emissions Testing: Use one full bottle and drive for 50–100 miles
- If CEL is On: Use immediately and monitor progress
Is Boost Up Catalytic Converter Cleaner Safe?
Yes. Boost Up is designed to be:
- Safe for oxygen and lambda sensors
- Non-corrosive to metals
- Compatible with modern and older gasoline engines
- EPA-registered and emissions-system safe
However, it is not suitable for diesel engines or electric vehicles.
What Results Can You Expect?
✅ Real-World Benefits:
- Reduced emissions (helps pass smog tests)
- CEL turns off (in some cases)
- Increased MPG
- Quieter and smoother engine operation
- No more sulfur/rotten egg smells
⚠️ Limitations:
- Not effective on physically damaged or melted catalytic converters
- Cannot fix problems caused by bad oxygen sensors or exhaust leaks
- May require multiple treatments for very dirty systems
