Is Fuel Additive Harmful to New Cars?

[StAaron]

For new cars with less than 20,000 kilometers on the odometer, it is unnecessary to add fuel additive. For vehicles exceeding 20,000 kilometers, it should be added as needed, generally one small bottle per tank of fuel. Long-term use of fuel additives can be harmful to the engine. Excessive use can increase carbon deposits in the combustion chamber, and if excessively added over a long period, it may even cause engine knocking, detonation, and worsen vehicle exhaust emissions. Below is additional information: 1. Driving Habits: The driver's habits have a greater impact on the car than the use of fuel additives. For example, frequent slow driving in urban areas with stop-and-go traffic can easily lead to engine carbon deposits. 2. Function of Fuel Additives: The main function of fuel additives is to increase the octane value of gasoline, making it burn more completely and reducing the formation of carbon deposits. This helps maintain engine power and fuel consumption, preventing decreased engine power and increased fuel consumption due to excessive carbon deposits.
