What is the impact of using the wrong fuel type in a vehicle?

Using the wrong fuel type in a vehicle can lead to potential knocking and engine damage due to the combustion characteristics of the fuel not matching the engine's design specifications. Most vehicles are engineered to operate optimally on a specific type of fuel, which is usually designated by the manufacturer.

For example, a vehicle designed to run on premium gasoline may experience knocking (premature combustion of the air-fuel mixture) when using regular gasoline. This knocking can lead to severe engine issues, such as damage to pistons, valves, and the overall cylinder head. Over time, continuous use of the incorrect fuel can result in more significant mechanical failures and costly repairs, compromising the vehicle's performance and longevity.

In contrast, while some might hope that using a different fuel could lead to better performance or efficiency, this is often not the case. Fuel types that do not meet the engine's requirements can cause detrimental effects rather than improvements in power or engine life.
