Can a Car Designed for 92 Octane Use 95 Octane?

[SanElliott]

Can a Car Designed for 92 Octane Use 95 Octane? A car designed for 92 octane gasoline can use 95 octane gasoline. 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, but this can easily lead to carbon deposits. These two types of gasoline should not be mixed together, as mixing them places a burden on the engine. If not careful, prolonged use of mixed gasoline can potentially cause engine knocking. Gasoline is a volatile and flammable hydrocarbon mixture liquid derived from the fractional distillation, cracking, or pyrolysis of petroleum.
