Can 92 and 95 octane gasoline be mixed together?

[LaDaniel]

92 and 95 octane gasoline should not be mixed together. Long-term mixing of different octane ratings will affect the service life of the car's ignition system, fuel injectors, and spark plugs. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation or cracking, which can be used as fuel and appears as a transparent liquid. 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline consists of 95% isooctane and 5% n-heptane. The main difference between the two lies in the purity of isooctane. The higher the purity of isooctane, the stronger the anti-knock performance of the gasoline.
