Does adding fuel additive have any impact?

Adding fuel additive has no negative impact. Fuel additive, also known as fuel system cleaner, primarily functions to remove carbon deposits, which has always been its main selling point. Additionally, it helps maintain the engine and fuel system. Some specialized fuel additives can also improve the anti-knock properties of fuel. Composed mainly of nano-molecules, cleaning activation factors, and over a dozen components including antioxidants, corrosion inhibitors, and demulsifiers, fuel additives are specifically designed to target harmful elements in fuel such as sulfur, gum substances, and engine carbon deposits. This results in enhanced power output, improved combustion, as well as benefits like oxidation resistance, wear resistance, cleaning, dispersion, demulsification, corrosion prevention, and lubrication.
I've seen many experiences with fuel additives over the years, and having driven for more than two decades, I've used them frequently myself. Adding fuel additives does have some noticeable effects: it helps clean carbon deposits in the engine, leading to more complete combustion and a slightly smoother acceleration feel. The difference is especially noticeable in older cars—my 150,000-kilometer Ford, for example, started much more smoothly after using it, with reduced engine vibrations. However, don’t expect a night-and-day transformation; the improvements are subtle—things like fuel efficiency might improve by 1-2%, but the savings are minimal. The key is choosing reputable brands; cheap products might clog fuel injectors or damage sensors, costing you more in repairs. I add a high-quality additive every 5,000 to 6,000 kilometers to help extend the engine's life and maintain its condition. Over the long term, it’s also slightly more eco-friendly, as tailpipe emissions become cleaner. In summary: using fuel additives can be beneficial, but it’s crucial to match them to your car’s condition and choose the right product—don’t just follow trends blindly.
As a car enthusiast, I've tested the effects of fuel additives. Adding them can dissolve carbon deposits and improve combustion efficiency, giving my car a slight horsepower boost and reducing fuel consumption by a fraction of a liter per 100 kilometers. The principle is simple: the additives attach to deposits to soften and clean them. But the impact isn't magical; the effect is minimal on new cars—my compact car showed little change after adding it. However, my friend's high-mileage Toyota had quieter engine noise after use. Dosage matters; overuse or low-quality products can cause issues, like oxygen sensor failures. I recommend adding it before long trips to maximize the cleaning effect. Don't believe exaggerated ads; real savings are limited—maybe just 10 or 20 bucks a month. Combining it with regular maintenance is safer.
I usually drive for grocery shopping and picking up the kids, and occasionally try fuel additives. After adding it, I feel the engine runs smoother and starts a bit faster. I tracked the fuel consumption and saved about half a liter in the city, not a big difference but still a small benefit. I consulted a repair shop, and the technician said regular use can prevent carbon buildup, so I add a bottle of a well-known brand every 5,000 kilometers. The effect varies from person to person; it might be more noticeable with older cars, but don't spend too much expecting miracles. The main thing is it's not troublesome—just pour it into the fuel tank. Keeping the car running well is the priority; saving money is secondary.
