How often should fuel additive be added?

[LaDonovan]

Fuel additive can be added once every 1,000 kilometers or one bottle per tank of fuel. Functions of fuel additive: The purpose of fuel additive is to solve the carbon deposit problem in the fuel system of fuel injection vehicles, quickly restore the engine to optimal working condition, and compensate for certain deficiencies in gasoline properties while imparting new beneficial characteristics (improved atomization, reduced wear, engine protection, lower emissions, etc.). Benefits of using fuel additive: Using fuel additives can dynamically remove carbon deposits inside the engine and prevent the formation of hard carbon deposits, which is essential for maintaining the vehicle in good operating condition.
