What to Do If You Accidentally Fill a Car Requiring 95 Octane with 92 Octane Gasoline?

[AvaDella]

If you accidentally fill a car that requires 95 octane gasoline with 92 octane, there is generally no need for special maintenance if it happens occasionally or involves mixing different grades of gasoline. However, it is recommended that for vehicles normally using 95 octane gasoline, after filling with 92 octane, you should use up the current fuel before refilling with 95 octane. Below are some additional details: 1. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. The higher the proportion of isooctane, the better the anti-knock performance. 2. Gasoline is a mixture. Although occasional mixing or using the wrong grade is not a major issue, prolonged mixing should be avoided. To ensure vehicle safety and performance, it is best to clearly distinguish and use the correct octane rating. Otherwise, it can directly affect the engine, shorten the lifespan of spark plugs, and lead to increased exhaust emissions.
