AUTOPROFI Oxygen Sensor & Catalytic Converter Cleaner — Pack of 2, Preventive Maintenance for Gasoline & Diesel

AUTOPROFI OXICAT is a preventive exhaust-system treatment that dissolves soot and carbon buildup in oxygen sensors, catalytic converters and the full exhaust path when driven to operating temperature.

Developed by CTP/bluechem GROUP and sold under the AUTOPROFI name, OXICAT is a maintenance additive designed to be introduced into the engine and exhaust stream to help remove accumulated carbon and soot. It is formulated for both gasoline and diesel engines and activates once the catalytic converter reaches its required operating temperature. Intended for routine use rather than as a repair product, OXICAT supports emissions-related performance and can be part of a preventative care schedule to reduce the risk of exhaust-related faults.

How does OXICAT work while driving?

OXICAT circulates through combustion and exhaust channels and chemically targets carbon and soot that impede oxygen sensors and catalysts. It becomes effective when the catalytic converter reaches its normal working temperature, allowing deposits to dissolve and be flushed out through normal exhaust flow.

• Introduced via fuel or designated dosing point per product instructions.
• Activated by catalytic converter operating temperature.
• Helps free clogged oxygen sensors and catalyst surfaces.
• Flushes dissolved residues out of the exhaust system.

When should I use OXICAT in my vehicle maintenance routine?

Use OXICAT periodically as a preventive measure—especially before emissions tests, after many short trips, or when you notice reduced exhaust efficiency. Regular dosing helps limit long-term deposit accumulation and maintains more consistent sensor readings and catalyst function.

• Schedule treatment every few thousand miles or before inspection tests.
• Recommended after long periods of short-trip driving where deposits build up faster.
• Ideal before planned emissions or diagnostic checks.

Is OXICAT safe for my engine and exhaust components?

OXICAT is engineered for use in both gasoline and diesel vehicles and is formulated to be compatible with exhaust catalysts and oxygen sensors when used as directed. It is not a substitute for mechanical repair and should be used as part of regular maintenance to help prevent issues rather than fix existing hardware failures.

• Designed for safe, routine use on modern engines.
• Made in Germany and TUV certified for professional standards.
• Not intended to repair physical damage or replace worn parts.

How long before I see results after treatment?

Because OXICAT requires the catalytic converter to reach and sustain operating temperature, benefits can appear after a single treatment driven under appropriate conditions, though noticeable improvements are often seen with regular use. Results vary by vehicle, condition of the exhaust system and driving profile.

• Some improvement may appear after one full treatment cycle at operating temperature.
• Best results with repeated, scheduled applications as part of preventive care.
• Vehicles with heavy, long-term buildup may need mechanical inspection in addition to chemical treatment.

Who is this for: AUTOPROFI OXICAT is aimed at vehicle owners and fleet managers who practice preventive maintenance, drivers preparing for emissions inspections, and technicians looking for a professional-grade additive to support exhaust-system health. It suits gasoline and diesel cars and light commercial vehicles where routine decarbonizing helps maintain sensor accuracy and catalytic efficiency. Remember that OXICAT supports upkeep and is not a substitute for mechanical diagnosis or repair when hardware failures occur.
