What Causes the Smell of Gasoline in a Car?

[Haymitch]

Here are the reasons why a car might smell like gasoline: 1. Gasoline leakage: After prolonged use, gasoline pipes may develop cracks, leading to gasoline leakage. The gasoline odor can enter the car through the air conditioning system. Additionally, aging of the carbon canister rubber hose can cause gasoline vapor leakage. 2. Lack of warm-up preparation: Not warming up the car before driving and overfilling the fuel tank can both result in a gasoline smell inside the car. Below is additional information on the differences between 95# and 92# gasoline: 1. Composition ratio: 95-octane gasoline contains 95% isooctane and 5% n-heptane, while 92-octane gasoline contains 92% isooctane and 8% n-heptane. 2. Anti-knock performance: 95-octane gasoline has higher anti-knock properties, whereas 92-octane gasoline has lower anti-knock properties.
