These blockages can restrict fuel flow, resulting in reduced power, poor engine performance, and even potential engine stall. For instance, if a fuel injector becomes clogged, it may spray fuel inefficiently or not at all, leading to misfires and reduced engine efficiency.

High-quality fuel, on the other hand, is carefully refined to meet specific standards and specifications. It undergoes processes to remove impurities and ensure a consistent viscosity, making it less prone to causing injector issues. Premium-grade fuels often have additives that help clean and protect the fuel system, including the injectors. These additives can help prevent the buildup of deposits and maintain the injector's performance over time. Using such fuel can lead to smoother engine operation, improved fuel efficiency, and reduced wear on engine components.

Furthermore, the impact of fuel quality extends beyond blockages. Poor-quality fuel may contain water or other contaminants that can cause corrosion within the fuel system, including the injectors. This corrosion can lead to injector damage, leaks, and even premature failure. In some cases, the presence of water in the fuel can cause electrical issues, as water can interfere with the electrical connections within the fuel injectors. This can result in erratic behavior or complete failure of the injector, requiring expensive repairs or replacements.

To minimize the risk of injector blockages and damage, it is recommended to use high-quality, premium-grade fuel whenever possible. Regular maintenance, such as fuel system cleaning and injector maintenance, can also help prevent issues. Additionally, keeping the fuel tank relatively full can minimize the exposure of the fuel to air, reducing the chances of water condensation and other contaminants. By understanding the relationship between fuel quality and injector health, vehicle owners can take proactive measures to ensure their cars' longevity and optimal performance.

Over-fuelling Risks: Potential consequences of over-fuelling, including injector clogging and engine misfires

Over-fuelling, or adding too much fuel to a vehicle's engine, can have several detrimental effects on a car's performance and longevity. One of the primary risks associated with over-fuelling is injector clogging. Fuel injectors are responsible for precisely metering and delivering the correct amount of fuel to the engine's cylinders.
