Is It Useful to Add Gasoline Additives Afterwards?
2 Answers
Adding gasoline additives afterwards is useful, and its related functions are as follows: Cleaning the Fuel System: High-quality gasoline additives contain purification factors that can remove harmful substances such as gum deposits in the fuel and engine carbon buildup. Continuous use of additives can eliminate carbon deposits in the fuel injectors, intake valves, and intake manifolds of the fuel system, restoring the vehicle's original power and maintaining optimal performance over the long term. Improving Atomization: Gasoline additives utilize nano-molecular materials to directly attack the long-chain carbon bonds in fuel molecules, creating "micro-explosions" in the combustion chamber. This results in secondary atomization of the gasoline, promoting complete combustion, improving thermal efficiency, and reducing fuel consumption. Real-world vehicle comparison tests show that gasoline additives can save 3-15% of fuel. This is particularly noticeable during long-distance highway driving, where fuel savings are more significant and can be directly felt.
I've been driving for over 20 years and regularly use fuel additives. They're quite useful for cleaning the fuel system, reducing carbon deposits, and making the engine run smoother. For example, once when my engine had slight vibrations, I added a bottle of additive after refueling, and after driving a few hundred kilometers, the issue disappeared. The key is to follow the instructions for the correct ratio and not overuse it—a 500ml bottle is enough for one tank of fuel. Benefits include improving fuel efficiency by about 5%-10%, enhancing acceleration response, and preventing major issues like fuel injector clogging. I use it every 5,000 kilometers and prefer reputable brands like 3M or STP for reliability. Adding it post-refuel is standard practice—whether the tank is empty or full doesn't matter, but avoid adding it when the engine is hot to prevent burns. Overall, it's safe and convenient, and I recommend giving it a try.
