Can 98 and 95 Octane Gasoline Be Mixed?

[IkerAnn]

No, they cannot be mixed. Mixing gasoline can easily damage the car's engine. Additionally, when choosing the gasoline octane rating, do not select one lower than the manufacturer's specified rating, as this may cause issues such as insufficient power and poor acceleration in the vehicle. Below is relevant information: 1. Gasoline with different octane ratings has different levels of octane. The higher the octane rating, the higher the octane value, and gasoline with a higher octane value has better anti-knock properties. 2. Since the nationwide implementation of the China V emission standards, the fuel octane ratings have been redefined. The original 93 and 97 octane gasoline have been replaced with 92 and 95 octane gasoline, and 98 octane gasoline has been added. 95 octane gasoline indicates that it contains 95% octane, while 98 octane gasoline contains 98%. The octane rating of fuel to be used in a car is determined by the compression ratio of the car's engine cylinders. 3. Cars with a compression ratio between 8.5 and 9.5 generally use 92 or 95 octane gasoline; cars with a compression ratio greater than 9.5 should use 98 octane gasoline.
