What type of gasoline should the Xingyue L use?
1 Answers
The 1.5T model of the Xingyue L uses 92-octane gasoline, while the 2.0T model uses 95-octane gasoline. Differences between 92-octane and 95-octane gasoline: 92-octane and 95-octane gasoline have different octane ratings and anti-knock properties. Their ignition temperatures also differ. The engine piston compresses air to perform work—for example, 92-octane gasoline ignites at 100 degrees, while 95-octane ignites at 110 degrees. When the cylinder compresses air and the temperature rises to 105 degrees, 92-octane gasoline may auto-ignite, causing engine knocking. Using 95-octane gasoline prevents premature ignition and avoids knocking. The type of gasoline a car uses depends on the compression pressure of the air in the cylinder—higher pressure leads to higher temperatures. Meaning of gasoline octane ratings: Common gasoline octane ratings in China include 92 and 95. The octane rating indicates the gasoline's anti-knock quality—higher octane gasoline has better anti-knock performance. The compression ratio reflects engine performance and efficiency. Generally, higher compression ratios require higher-octane gasoline; otherwise, premature ignition or knocking may occur. Differences between diesel and gasoline: Diesel ratings differ from gasoline—diesel ratings represent the freezing point. Using diesel unsuitable for the local climate can lead to wax crystal formation, clogging fuel lines and affecting engine performance. Due to significant climate and temperature differences between northern and southern regions, diesel should be selected based on the usage environment.
