Can Poor Quality Fuel Cause the Engine Light to Illuminate?

[VanessaAnn]

Poor quality gasoline can indeed cause the engine warning light to illuminate. Here are the specific details: Hazards: Substandard or poor-quality gasoline can trigger the engine warning light. Shortly after refueling at a non-compliant gas station, the engine warning light on the dashboard may illuminate. This occurs because low-quality gasoline leads to incomplete combustion of the air-fuel mixture during engine operation, causing the warning light to activate. While this does not immediately affect driving safety, it can cause varying degrees of harm to the engine. Excessive Silicon Content: If the gasoline contains excessive silicon, the combustion process produces white silicon dioxide powder, which can adhere to the oxygen sensor and render it ineffective. Such gasoline can cause abnormal engine operation within the span of a single tank of fuel, potentially leading to complete vehicle breakdown.
