Which Cars Use 97 Octane Gasoline?
2 Answers
Automobiles specified in the maintenance manual as suitable for 97 octane gasoline can use 97 octane gasoline. Below is detailed information about engine oil: Overview: Engine oil, also known as engine lubricant, is referred to as Engine-oil in English. It has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions for the engine, including lubrication and wear reduction, auxiliary cooling, sealing to prevent leaks, rust and corrosion prevention, and shock absorption. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricant, determining its fundamental properties. Additives are used to compensate for and improve the shortcomings of the base oil, providing certain new characteristics, making them an essential part of the lubricant.
I drive a used BMW 3 Series, which requires 97-octane gasoline due to its high engine compression ratio and turbocharged design. If I don't use it, the car shakes badly and the noise increases. I remember once trying to save money by using 93-octane, and the engine almost knocked when I was on the highway. The mechanic later told me that high-performance or luxury cars like Mercedes and Audi's high-end models all need 97-octane fuel because the higher octane rating prevents pre-ignition and protects the engine. For regular family cars like a Toyota Corolla, 92-octane is sufficient. Always check the fuel cap or the manual for the recommended octane rating—don't try to save small money at the risk of major repairs. Safety first.
