What Causes Car Shaking After Adding Fuel Additive?

[DelAdelyn]

Occasional body shaking occurs because the fuel containing the additive gathers deposits and carbon buildup in bottleneck areas of the fuel system, causing localized blockages that disrupt fuel supply. Below is an explanation of car shaking after adding fuel additive: 1. The fuel additive is actually working, which is a normal phenomenon. This effect will gradually diminish after using 3-5 tanks of fuel containing the additive; 2. Due to the cleaning effect of the fuel additive on the fuel intake system, deposits and carbon buildup on the fuel injectors, intake valves, and intake manifolds are gradually cleaned off. These deposits and carbon enter the combustion chamber along with the gasoline, but some may not burn completely, occasionally causing black smoke from the exhaust pipe; 3. While driving, gasoline containing the additive enters the fuel intake system, automatically cleaning it and gradually removing deposits. This helps maintain optimal spray patterns in the fuel injectors, ensuring complete fuel combustion, improved thermal efficiency, and fuel savings. For new cars, the fuel additive helps keep the fuel intake system unobstructed and clean, maintaining the vehicle's fuel consumption at the best level.
