Our three-way catalytic cleaning agent is carefully prepared from dimethyl ether and diethyl ether. Designed specifically to remove carbon deposits and restore engine efficiency, improve combustion activity, increase overall power, improve fuel economy and vehicle performance. The method of using is extremely convenient: it is recommended to add 1-2 bottles of catalytic cleaner for every 30-60 liters of gasoline or diesel every time you refuel. It is recommended that every 6 refueling is a basic usage cycle, and 12 consecutive use is an ideal effect cycle, which can continuously improve the cleaning effect. After the first addition, the carbon deposit may fall off, causing poor oil flow or slightly shaking the engine. This is a normal reaction. Typically, the first 3-5 cans of oil are the process of removing carbon deposits and decomposing colloids. After completing this stage, the fuel saving effect will be more significant. And insist on regular use, it can effectively clean the fuel system and three-way catalyst, reduce carbon deposition, improve combustion efficiency, and protect engine performance for a long time. This product is suitable for gasoline and diesel vehicles and can be used in new and old models. And it can effectively purify exhaust gas and reduce harmful emissions, making the vehicle cleaner.  Net content: 100ml Product name: Three-way catalytic cleaning agent Keywords: Engine cleaning agent Gross weight: 117g Ingredients: dimethyl ether, diethyl ether Packaging size: 12 x 3.9 x 3.9cm Product size: 11.8 x 3.7cm Box meter: 56 x 36 x 21.5cm Weight of one box: 24.15kg Shelf life: 3 years Storage method: Please store it in a cool and covered area Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
