Is it necessary to add compound additives?

[OLucas]

It depends on whether gasoline compound additives need to be added based on the condition of the vehicle. Generally, it is not necessary for new cars. If the car has been in use for a long time, adding them can improve engine performance. Gasoline compound additives refer to fuel additives that enhance engine performance. Gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through fractionation and cracking, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. Principle of thermal expansion and contraction: Thermal expansion and contraction refer to the property of objects expanding when heated and contracting when cooled. This occurs because the movement of particles (atoms) within the object changes with temperature. When the temperature rises, the vibration amplitude of the particles increases, causing the object to expand; when the temperature drops, the vibration amplitude decreases, causing the object to contract.
