What to Do If a Car Uses Deteriorated Gasoline?

[Ramona]

It is necessary to completely remove the remaining gasoline in the fuel tank and refill with higher-quality gasoline. Additionally, the fuel injectors and combustion chamber need to be cleaned, and the fuel filter and fuel pump should be replaced to prevent clogging by impurities. Below are the reasons for gasoline deterioration: 1. Exceeding the shelf life: Most gasoline has a shelf life of 3 months, which can be extended to 6 months in a sealed environment. The composition of gasoline includes volatile substances such as octane, which gradually evaporate due to storage conditions and prolonged placement, leading to gasoline deterioration. 2. Water contamination: If water droplets or vapor mix into the gasoline, it can cause solidification. Water molecules mixed into the gasoline can produce bacteria in the engine, causing damage. 3. Oxidation: Among the components of gasoline, hydrocarbons are most prone to react with oxygen. After oxidation, gasoline produces an acidic odor.
