What Causes Jerking Sensation After Adding Fuel Additive?
2 Answers
Jerking sensation after adding fuel additive is primarily caused by excessive carbon deposits in the combustion chamber. Below are detailed explanations about fuel additives: 1. Adding sequence: Add the fuel additive before refueling with gasoline. This allows the fuel additive to mix thoroughly and evenly under the impact of gasoline injection, achieving optimal usage effects. 2. Functions: Fuel additives, also known as fuel system cleaners, mainly serve to remove carbon deposits, maintain the engine and fuel system. Some specialized fuel additives can also improve fuel's anti-knock properties (octane rating). Composed of nano-molecules, cleaning activation factors, and over ten components including antioxidants, anti-corrosives, and demulsifiers, fuel additives are specifically designed to target harmful substances in fuel such as sulfur, gum deposits, and engine carbon buildup. They enhance power output, promote combustion, provide anti-oxidation, anti-wear, cleaning, dispersing, demulsifying, anti-corrosion, and lubrication effects.
I've been driving for over a decade and have tried several fuel additives. Sometimes after adding them, I notice the car jerks or hesitates during acceleration. This mainly happens because fuel additives loosen old deposits or sludge in the fuel tank and lines during cleaning. These contaminants can suddenly clog the fuel injectors or throttle body, disrupting fuel flow. When fuel supply is inconsistent, engine combustion becomes unstable, especially noticeable during idling or acceleration. My advice is to choose reliable brands, avoid overuse, and follow the instructions carefully. If jerking occurs, try driving at highway speeds or using a dedicated cleaner to flush the system. This helps the engine run smoothly and prevents long-term damage.
