Is it necessary to use 95-octane gasoline for new cars?
1 Answers
During the break-in period of a new car, you can fill up with 95-octane gasoline. Using higher-octane gasoline during the break-in period can be beneficial because 95-octane gasoline has a higher octane rating and better combustion properties, which can effectively promote more complete combustion inside the engine, enhance engine performance, and reduce carbon deposits. Here are some related details: 1. 95-octane gasoline: 95-octane gasoline consists of 95% isooctane and 5% n-heptane. High-compression engines should use high-octane gasoline. If low-octane gasoline is used in a high-compression engine, it can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. Of course, high-compression engines can also use lower-octane gasoline, but you should not blindly choose gasoline based on the compression ratio. Instead, follow the manufacturer's recommendations for fueling. 2. Anti-knock properties: Anti-knock properties refer to the ability of gasoline to resist knocking when burned in the engine. It is a primary indicator of gasoline combustion performance. Knocking is caused by abnormal combustion of gasoline in the engine. The octane number is a measure of fuel's resistance to knocking—the higher the octane number, the stronger the anti-knock properties.
