Is It Necessary to Use Gasoline Additives?

It is not mandatory to use them. Here is a relevant introduction about the functions of fuel additives: Cleaning effect: The effect of this function is not immediate; its value can only be reflected after long-term use. Engines that use fuel additives over a long period will have significantly less carbon buildup. Fuel saving: Additives also have a fuel-saving effect, though it is not very noticeable, with savings of only about 5%. The effect may be more pronounced for cars that frequently travel long distances. The quality of additives available on the market is hard to guarantee, and using inferior additives is harmful rather than beneficial. It is best to purchase them from 4S stores, even though the price may be higher, as at least you can hold them accountable if any issues arise.

I don't think fuel additives are absolutely necessary, but it depends on the situation. As an experienced driver, my observation is: If you mostly drive in urban areas and notice unstable idling or significantly increased fuel consumption, adding a suitable additive might help. It can clean carbon deposits inside the engine, improve combustion efficiency, and give a slight power boost. However, it's not a cure-all. Modern gasoline already contains cleaning agents, so new vehicles generally don't need extra additives. I personally prefer adding preventive additives during oil changes or regular maintenance intervals – mid-range brands work just fine, no need to overspend on premium products. In conclusion, decide based on your vehicle's condition, don't expect it to solve major issues, and remember that consistent routine maintenance is what really matters.

From a car maintenance perspective, fuel additives can indeed help clean fuel injectors and intake valves, reducing carbon buildup, which improves engine performance and fuel economy. Vehicles frequently driven short distances or with frequent start-stop cycles are prone to deposit formation, and additives may provide a slight improvement, though they aren't always necessary—especially for newer cars or engines using high-quality gasoline. I recommend using them in line with your vehicle's maintenance cycle, such as adding them every 10,000 kilometers, to maximize benefits. Additionally, choosing certified additive brands is crucial to avoid damage to sensors or other side effects from low-quality products. Maintaining overall vehicle upkeep is far more reliable than relying solely on additives.

My old car feels better after using the additive, and the engine noise has decreased a bit. However, it's not very necessary, so don't add it randomly when the car is running normally. If the car is old or often driven at low speeds, adding it can help remove carbon deposits and prevent minor issues, but don't overdo it—the expense isn't worth it.

Gasoline additives claim to save fuel and be environmentally friendly, but honestly, their effects are limited. The small amount of fuel savings cannot offset the cost, and the key still lies in daily maintenance habits.

As a novice driver, my instructor told me that additives can protect the engine, but they must be used according to the instructions. They can clean the system, but beginners should not try them casually. It's better to consult professionals first to ensure safety.
