Is it necessary to use 95 octane gasoline for the first few times with a new car?

It is not necessary to use 95 octane gasoline for the first few times with a new car. Here is some information about refueling a new car: 1. The difference between 92 and 95 octane gasoline: 92 octane and 95 octane gasoline provide the same power, with no difference. The difference lies in the octane rating, with 95 octane gasoline having higher anti-knock properties than 92 octane. 2. Refueling conditions: If the purchased vehicle has a naturally aspirated engine, you can directly use 92 octane gasoline, and there is no need for 95 octane. However, if the vehicle is equipped with a turbocharged engine, then 95 octane gasoline must be used.

As a veteran driver with twenty years of experience, I can tell you that there's no need to overthink using 95-octane fuel for a new car. The manufacturer has already placed a recommended fuel label inside the fuel tank cap—just follow that for peace of mind. When I bought my Hyundai Elantra, I strictly used 92-octane fuel, and after driving over 80,000 kilometers, the engine remains quiet and powerful. Some people believe that higher-octane fuel can protect the engine, but in reality, the engine's compression ratio is what truly matters. Think about it: new cars come with lubricating systems pre-treated with protective agents, and fuel lines are already conditioned. Using higher-octane fuel might actually raise combustion temperatures, potentially leading to carbon buildup. Saving 50 cents per liter could even cover an extra maintenance session. Remember, after driving the first 1,000 to 2,000 kilometers, have a mechanic check the combustion chamber during the initial service—that's the most practical approach.
