How Often Should Fuel Additives Be Added?
2 Answers
Currently, there is no specific time frame for adding fuel additives. Generally, it is recommended to add fuel additives every 5,000 to 10,000 kilometers. The functions of fuel additives include removing carbon deposits, reducing fuel consumption, and restoring engine power. Fuel additives are a type of automotive chemical and are commonly referred to as the third generation of gasoline detergents. They can quickly restore engine performance, compensate for certain deficiencies in gasoline properties, and impart new beneficial characteristics to gasoline. Since direct injection systems spray gasoline directly into the combustion chamber, only PEA (polyether amine) additives can withstand such high-temperature and high-pressure environments without forming deposits.
I usually add fuel system cleaner every 8,000 kilometers or so because my car frequently gets stuck in city traffic, making the engine prone to carbon buildup. After adding it to the fuel tank and driving a few dozen kilometers, I can clearly feel smoother acceleration and more stable fuel consumption. Following the manufacturer's maintenance recommendations is the most worry-free approach—for example, if the maintenance manual suggests adding it every 5,000 to 10,000 kilometers. Choosing reliable products is crucial; mainstream brand additives have better compatibility, so don’t go for cheap, off-brand options. Gasoline quality also matters—if you’re using low-quality fuel in remote areas, it’s best to shorten the interval to every 6,000 kilometers. Otherwise, excessive carbon buildup can lead to costly repairs. Maintaining this habit can also help extend the engine’s lifespan.
