Is it necessary to add gasoline compound when refueling?

It is not necessary to add gasoline compound when refueling. Gasoline compound, also known as fuel additive, can be added according to the owner's preference, and there is generally no mandatory requirement. The following is an introduction to the types of fuel additives: 1. Cleaning type: When the vehicle obviously feels that the fuel supply is not smooth, and the carbon deposits in areas such as the valve and fuel injector are serious, this type of fuel additive can be appropriately selected. 2. Maintenance type: The main function of this additive is to inhibit the formation of carbon deposits and ensure the normal operation of the valve and fuel injector. 3. Octane number adjustment type: Octane number refers to the fuel's resistance to detonation. For example, the octane number of 92 gasoline is 92. This type of fuel additive is mainly used to improve the octane number of the fuel to a certain extent, enhance the quality of the oil, and at the same time, it can play a role in energy saving and emission reduction. 4. Comprehensive type: This additive combines the characteristics of the above three products and is a technically advanced fuel additive.

I've been driving for many years, and adding gasoline additives is not a must. Modern gasoline already contains cleaning agents that help protect the engine. If your car is new or runs smoothly, there's no need for extra additives. However, my old car once had issues like increased fuel consumption and lack of power, so I occasionally added a bottle of carbon-cleaning additive, like Shell's, and felt it slightly improved fuel efficiency and throttle response. But keep in mind, this doesn’t solve major problems, and you don’t need to add it to every tank—that’s just a waste of money. When choosing a product, check its reputation to avoid low-quality ones that might harm the engine. It’s better to refer to the owner’s manual for recommendations. In daily driving, frequent highway trips can also naturally clean carbon deposits. In short, whether to add it depends on your car’s condition and needs—don’t blindly follow trends.

From a practical standpoint, whether to add fuel additives depends on cost-effectiveness. These additives, such as cleaners, are mainly used to remove carbon deposits and improve combustion efficiency, but they aren't necessary for every refuel. A bottle of additive costs around 20-30 yuan, adding to the expense per tank. If your vehicle is running normally, skipping it is fine. However, if your car shows minor symptoms like idle shaking or higher fuel consumption, using an additive periodically might save money in the long run—reducing repair costs or improving fuel economy. Personally, I add a bottle every few thousand kilometers and notice smoother engine performance and cleaner exhaust. But always choose reputable brands; cheap, unknown products can harm your engine. Modern gasoline is already optimized, so unless you're preventing specific issues, additives aren't essential. Proper maintenance matters more.

Let's talk about car maintenance knowledge. Gasoline additives primarily serve a cleaning function, helping to remove engine carbon deposits and improve the fuel system. Whether to add them depends on your driving habits and vehicle condition. For new cars or those frequently driven on highways, the additives in gasoline are sufficient, and no extra addition is needed. However, if you often encounter city traffic jams or take short trips, the engine is prone to carbon buildup, so adding a bottle of additive every six months can be beneficial. I recommend carbon-cleaning products, used according to the instructions without exceeding the dosage. Low-quality additives can be harmful instead. Choose reliable brands to ensure safety.
