How does bad fuel quality contribute to engine sputtering in Honda City?

Many fuel stations in Pakistan may sell low-quality o r adulterated fuel, which can cause combustion issues in modern engines. How does substandard fuel affect the engine performance of a Honda City, and what are the long-term risks of using poor-quality petrol? Are there any fuel additives that can help mitigate this problem?

How Bad Fuel Affects Engine Performance:

Incomplete Combustion: Low-quality fuel often has impurities like water o r higher concentrations of ethanol, leading to poor combustion. This can cause engine sputtering, hesitation, and poor acceleration.
Carbon Deposits: Bad fuel can lead to carbon buildup in the fuel injectors, combustion chambers, and intake valves, causing poor engine performance and misfires.
Fuel System Damage: Over time, poor-quality fuel can damage the fuel system components, including injectors, the fuel pump, and the fuel filter.

Long-Term Risks of Using Poor-Quality Petrol:

Increased Maintenance Costs: Constant use of poor fuel quality can result in clogged injectors, degraded spark plugs, and the need for more frequent repairs.
Reduced Fuel Efficiency: Substandard fuel results in inefficient combustion, leading to lower mileage and higher fuel consumption.

Mitigation with Fuel Additives:

Fuel additives can help clean fuel injectors and improve combustion. Products like Techron o r STP Fuel Injector Cleaner can be used to mitigate the effects of bad fuel and keep the fuel system cleaner.
However, the best long-term solution is to always fill up at reputable stations that offer quality fuel.
