Should Naturally Aspirated Engines Use 92 or 95 Octane Gasoline?

[McJade]

Naturally aspirated engines should use 92 octane gasoline. Precautions for refueling include: 1. Choose to refuel when the temperature is relatively low; 2. If the car is not used for a long time or used infrequently, keep the fuel level low; 3. Avoid refueling when a tanker truck is unloading fuel; 4. Turn off the engine when refueling a gasoline car; 5. Do not mix gasoline of different octane ratings. Long-term mixing of gasoline with different octane ratings can affect the lifespan of the car's ignition system, fuel injectors, and spark plugs. The components of a fuel tank include: fuel tank cap, baffle, fuel gauge sensor, fuel inlet and return pipes, fuel filler neck, and vent. The function of the fuel tank is to store the working fluid required by the hydraulic system, and it also serves to dissipate heat, precipitate impurities, and separate air bubbles from the liquid.
