Is Adding Fuel Additive Useful for Cars?

[WilliamAnn]

Adding fuel additive is useful for cars, but it only improves the octane rating of gasoline. The functions and usage methods of fuel additive are as follows: Functions of Fuel Additive: Fuel additive has a significant cleaning effect on the fuel intake system of a car, especially on the carbon deposits in the fuel injectors and intake valves, without causing adverse effects on the engine. The only drawback is that it cannot clean the throttle body. During driving, fuel additive can gradually clean the deposits in the fuel intake system, significantly improve fuel atomization, make combustion more complete, and increase thermal efficiency, thereby achieving a certain fuel-saving effect. Usage Method of Fuel Additive: Using fuel additive is quite convenient. Before refueling at a gas station, add the fuel additive to the car's fuel tank according to the recommended ratio, then add fuel. This way, the added fuel additive will quickly dissolve fully under the impact and vortex stirring of the fuel, ensuring a more uniform mixture of the fuel additive and fuel.

I think whether to use fuel additives depends on your car model and condition. I've used them several times and found they might help older cars by cleaning engine carbon deposits, improving fuel line flow, and making throttle response quicker. But for new cars, it's basically unnecessary—just a waste of money and might even clog fuel injectors. The key is to choose reputable brands; don't go for cheap knockoffs that could damage the engine. I'd recommend high-mileage car owners, say those with over 100,000 km, to give it a try while maintaining regular engine servicing and using high-quality engine oil for better reliability. Overall, fuel additives aren't a cure-all—don't expect big fuel savings. Their main role is auxiliary cleaning, while driving habits and maintenance truly affect fuel efficiency.

From my perspective, there are real doubts about the environmental benefits of fuel additives. Manufacturers claim they improve fuel efficiency and reduce emissions, seemingly making them air pollution-friendly. However, the production and transportation of these additives themselves increase carbon emissions. Honestly speaking, I've tried them a few times with negligible effects - driving smoothly and avoiding sudden acceleration proves more eco-friendly. Using substandard fuel additives might even contaminate soil and water sources. That's why I prioritize regular air filter replacements and high-quality unleaded gasoline to maintain engine health. This approach saves money while reducing carbon footprint, making fuel additives unnecessary. Ultimately, sustainable driving practices are what truly matter - don't fall for marketing gimmicks.

I've been driving for seven or eight years and have used fuel additives, but I really don't feel they make much of a difference. I bought a new bottle and added it to the fuel tank, but there was no change in engine noise, and fuel consumption didn't drop much—it's pretty much the same as regular maintenance. It might be useful for some old cars with severe carbon buildup, but my car doesn't have any issues, so it's just a waste of money. It's more practical to change the oil once a year and check the spark plugs. In short, I personally don't think it's necessary to add them—don't blindly follow the trend.
