What to Do If 95 and 92 Gasoline Are Mixed?

[OLuna]

Mixing 95 and 92 gasoline occasionally once or twice has little impact. Short-term mixing of different gasoline grades generally does not require special vehicle maintenance. However, long-term mixing of different gasoline grades will affect the service life of the car's ignition system, fuel injectors, and spark plugs, advancing the vehicle's overhaul time. The gasoline grade is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Isooctane has good anti-knock performance, and its octane number is defined as 100. N-heptane has poor anti-knock performance and is prone to knocking in gasoline engines, so its octane number is defined as 0. If the gasoline grade is 90, it means that the gasoline contains 90% isooctane and 10% n-heptane, which has the same anti-knock performance as standard gasoline.
