Can a car that has been using 92 octane switch to 95 octane gasoline?
2 Answers
A car that has been using 92 octane can switch to 95 octane gasoline, but 92 and 95 octane gasoline should not be mixed. Long-term mixing of different octane ratings can affect the lifespan of the car's ignition system, fuel injectors, and spark plugs. Precautions for refueling include: 1. Choose to refuel when temperatures are relatively low; 2. If the car is not used for a long time or used infrequently, keep a small amount of fuel; 3. Avoid refueling when a tanker truck is unloading; 4. Turn off the engine when refueling a gasoline car; 5. Do not mix different octane ratings of gasoline. The components of a fuel tank include: fuel tank cap, partition, fuel gauge sensor, fuel inlet and return pipes, filler neck, and vent.
I've been driving this car for several years, usually filling up with 92 octane gasoline, and occasionally using 95 octane without any issues. The engine system automatically adjusts to adapt to different octane ratings, so it won't cause damage. I remember during a long trip when I switched to 95 octane, the engine felt quieter and acceleration was smoother, but this may vary from person to person. If the vehicle manual recommends 92 octane, there's no need to consistently upgrade to 95 octane to avoid wasting money, since 95 octane is more expensive. The key is to choose reputable gas stations to ensure good fuel quality. Don't worry about the risk of knocking—95 octane has a higher octane rating, which actually provides better anti-knock performance and can be beneficial for older cars or high-compression engines. In short, switching is safe, but keeping it simple is best—no need to overcomplicate things.
