Oxygen Sensor Cleaner Made in Germany Efficient Catalytic Converter Cleaner High-Performance Vehicle Cleaner for Gasoline, Diesel Engine Emission Cleaner for Turbo Charger, EGR Valve

I send this to my son every few weeks for his Lexus, which has around 220,000 miles. Lol Helps to keep the car running.

This product works great very good mileage and performance after I put it on my gas tank

I am hoping that it does what it says trying to clean my exhaust system

Was not able to turn off the engine light yet. Could be more problems than this can repair. Maybe it need more cleaning like more cans to put in the tank. But it did get more mpg after I empty the tank with the cleaner.

help my car alot

Awesome product noticed a right away difference smoother idle more power

Check engine light still comes on. code 420 Bank 1. wasted money

Easy to use
