Help to improve fuel efficiency, optimizes the engine performance. Product properties: For use in all Gasoline and Hybrid Engines. If the catalytic converter is lazy or clogged, we recommend our direct foam cleaner (DPF & catalytic Foam cleaner #8101). Use MotorPower Care catalytic converter cleaner regularly every 3-4 months or 3000 miles (which ever comes first). Instructions: Add Catalytic converter bottle to the fuel tank. Application Consumption: 250 ml mix with 7 to 12 gallons of gasoline. Mixing Ratio: 1:300 Reaction time: Works while the engine is running. Drive the vehicle for 40 minutes after adding it to the fuel tank, and every 10min, try to accelerate (floor it) the gas pedal while you are on open roads for a few seconds, repeat for a few times. Attention: We recommend inspecting the catalytic converter from the O2 sensor port for any cracks, by using an endoscope camera before using any cleaner. If catalytic converter is cracked, melted or broken then it's to late for any cleaner. Review: THIS STUFF WORKS! - Had a P0420 code on my 2009 Chevy HHR. Added cleaner to about 8 gallons of fuel, got on the freeway and drove as fast as I could for about 12 miles, stopped and added a few more gallons of GOOD fuel, started the car and the check engine light was OFF. I think the problem was aggravated by using cheap fuel. I recommend using top tier fuel only! Review: German products are very good all the time. - It works pretty well, I can see some difference on my engine running. ## Features - PROVEN TO REDUCE EMISSIONS — Government-tested results show HC reduced from 108 to 67 ppm and NOx from 986 to 332 ppm.
