OXICAT – Oxygen Sensor and Catalytic Converter Cleaner

OXICAT – Oxygen Sensor and Catalytic Converter Cleaner

OXICAT – Oxygen Sensor and Catalytic Converter Cleaner 800 500 Wilhelm Wust

Effective, fast, preventive – high-performance cleaner for the entire exhaust system (lambda probe, catalytic converter, turbo charger, EGR valve, etc.)

The product was launched on the international market for the first time in 2014 and was specially developed to unfolds its properties only during and after the combustion.

For optimal combustion of today’s fuels, in diesel and gasoline engines, special attention is paid to the lambda probe. This determines the residual oxygen in the exhaust gas and influences the fuel-air mixture through the measurement result.
Since 2018 we have also been offering a variant specially optimized for hybrid vehicles.

The lambda probe is the main sensor in the lambda control loop for catalytic exhaust gas cleaning. The aim is to minimize the emission of pollutants such as nitrogen oxides, hydrocarbons and soot. Factors influencing the measurement, such as coking, soot and oily deposits, reduce the measurement accuracy of the lambda sensor in the exhaust tract. These inaccurate measurement results are then sent to the OBD – On Board Diagnostic System – whereby the system begins to initiate changes to the fuel-air mixture. These changes cause major problems: the engine no longer burns cleanly, engine shudder, poor throttle response, bad idle, high fuel consumption and even activation of the emergency program are the consequences.

Possible error messages: P0420 catalytic converter efficiency, P0300 P03XX ignition or combustion misfires detected, P0171 mixture too rich, P0170 mixture too lean

The well-known error messages of the lambda probe, which the driver often notice via a yellow warning light, mean that the lambda probe has to be replaced in the workshops, which is very cost-intensive.


A mechanic and a customer discuss repairs that have been done on her vehicle.

The OXICAT – Oxygen Sensor and Catalytic Converter Cleaner from bluechemGROUP prevents the expensive replacement for the customer and ensures that the lambda probe is cleaned and thus delivers precise measured values. Since the exact fuel-air mixture is determined in this way, the engine works powerfully and reacts extremely precisely, while fuel consumption is significantly optimized. This in turn ensures the best possible exhaust gas values ​​and, in addition, deposits in the catalytic converter are permanently removed.


Satisfied customer after visiting the workshop.

We recommend using it every 10,000 km for both diesel and gasoline engines. It could not be easier to use: Simply add OXICAT to the fuel tank before refueling.

“bluechemGROUP in harmony with vehicles and environment.”
