Fuel additives are not flammable substances but are combustible under certain conditions. The main component of fuel additives is a high-molecular-weight ashless surfactant. This surfactant, when dissolved in automotive fuel, utilizes its strong adsorption, wetting, solubilization, and dispersion functions to break down and remove carbon deposits accumulated on metal surfaces, dispersing and encapsulating them into fine carbon particle micelles. Benefits of fuel additives: 1. Removing engine carbon deposits: Fuel additives are one of the most effective ways to clean engine carbon deposits. They contain molecules that purify gasoline. While not immediately effective, continuous use will clean certain internal components of the car, remove carbon deposits, and restore the vehicle's power. 2. Reducing abnormal engine wear: Carbon deposits inside the engine are one of the factors contributing to engine noise. High-quality fuel additives can reduce carbon deposit formation, thereby lowering engine noise. 3. Improving atomization efficiency: The most direct benefit of improved engine atomization efficiency is reduced fuel consumption. Higher atomization efficiency leads to better combustion efficiency, naturally lowering fuel consumption. This effect is more noticeable during long highway drives, which is one reason many car owners prefer to use fuel additives regularly. 4. Reducing vehicle emissions: Incomplete combustion in the engine leads to significant fuel waste, with black smoke being the most common symptom. Using fuel additives can improve this situation, avoiding fuel waste and making exhaust emissions more compliant with standards. 5. Extending engine lifespan: Car engines are costly, and prolonged use can lead to various issues. The molecules in fuel additives can protect the engine, extending its service life and preventing malfunctions that could cause unnecessary losses.

I've been driving trucks for over a decade and have used many fuel additives. These cleaners aren't fuel themselves, so they don't combust like gasoline does; they're designed to dissolve engine carbon deposits. When you add them to the fuel tank to mix with gasoline, the combustion of gasoline during engine operation carries away the dissolved deposits, and the cleaner is also partially burned to complete the cleaning. Once, I used the wrong brand and added too much, which made the engine shake more noticeably—luckily, I stopped using it in time. Remember not to use it as fuel or exceed the recommended amount; just add one can to a full tank to improve some power and fuel efficiency. For long-term maintenance, using reputable brands like 3M regularly can significantly extend your vehicle's lifespan, and older cars start up much faster.

I enjoy tinkering with car modifications and always like to research these additives. Fuel additives are essentially chemical solvents that do not contain combustible components, so they don’t burn directly; their role is to clean carbon deposits. When added to fuel, the detergent is catalytically decomposed by the high temperatures of the engine’s combustion, removing contaminants. I’ve tried buying a random bottle at a gas station and adding it to an old car—performance improved, but avoid low-quality products. If they contain impurities, they might clog the fuel injectors. When selecting one, check the product description to choose a formula compatible with your car model. It’s recommended to use it every 5,000 kilometers, but don’t expect it to replace fuel. After cleaning carbon deposits, the exhaust will become cleaner, and the car will run smoother.

As an environmental enthusiast, I prioritize the environmental impact of fuel additives. They don't burn like fuel themselves since their main component is surfactants; when mixed with gasoline and burned, they partially decompose to help reduce carbon deposits. After using reputable fuel system cleaners, I've noticed a slight reduction in particulate matter in the exhaust. However, choosing non-compliant products can generate harmful substances. I always opt for certified eco-friendly formulas like Shell's to minimize pollution risks. Simple periodic use (once in a while) is sufficient – don't rely on them too frequently to avoid resource waste.
