Must Fuel Additives Be Used Continuously for 6 Times?
2 Answers
Do not use continuously. Fuel additives do not need to be added consecutively. Excessive use can lead to increased carbon deposits in the combustion chamber while cleaning the intake valve deposits. If excessive addition continues, it may even cause engine knocking, detonation, and worsen vehicle exhaust emissions. Relevant details are as follows: 1. Composition: Fuel additives are functional substances added to gasoline to compensate for certain deficiencies in gasoline properties and to impart new excellent characteristics. The components of fuel additives are complex, but the main ones are combustion aids and cleaning agents. 2. Fuel Consumption: There is another type of fuel additive that reduces the probability of engine detonation by improving the anti-knock properties (octane number) of the fuel. However, long-term use of this method is not good for the car, as it can easily lead to the accumulation of a lot of carbon deposits, and conversely, fuel consumption may increase.
I've used fuel system cleaner a few times and know it's not mandatory to use it consecutively for six times. In principle, its effect on cleaning engine carbon deposits is gradual – a single dose can also alleviate certain issues like idle shaking or insufficient power. However, manufacturers designed the consecutive usage plan to achieve more thorough cleaning. If your car has severe carbon buildup, continuous use may yield more noticeable results. Based on my own vehicle's condition, I regularly add one bottle during each maintenance session for upkeep, without strict frequency requirements. The key is to observe the engine's response and follow the maintenance manual's recommendations. There's no need to rigidly adhere to the six-time rule.
