What happens if a car that uses 92 gasoline is filled with 95?
1 Answers
Occasionally using 95 gasoline in a car designed for 92 will not cause harm, but long-term use of 95 gasoline can affect the ignition system, fuel injection system, and engine. 1. Octane Rating: Gasoline with a higher octane rating indicates better anti-knock performance. For hydrocarbons of the same group, smaller carbon numbers result in better anti-knock performance and higher octane ratings. For hydrocarbons with the same carbon number, the octane rating decreases in the following order: aromatic hydrocarbons > isoparaffins and isoolefins > normal olefins and naphthenes > normal paraffins. For different straight-run fractions from the same crude oil, lighter fractions have higher octane ratings. For fractions with the same boiling range from different crude oils, the chemical composition varies, leading to different octane ratings. 2. Gasoline Differences: 95 gasoline consists of 95% isooctane and 3% n-heptane, while 92 gasoline has an octane rating of 92 and a n-heptane rating of 8.
