What grade of gasoline should the Xingyue use?
2 Answers
The Geely Xingyue uses 92-octane gasoline. This model offers two variants: the gasoline version uses 95-octane gasoline, while the gasoline + 48V mild hybrid system uses 92-octane gasoline. Relevant details are as follows: Reasons for using 92-octane gasoline in the Xingyue: 95-octane gasoline has a higher isooctane content and is designed for engines with higher compression ratios. The Geely Xingyue, a compact SUV under Geely Auto Group, has a relatively lower engine compression ratio. Using 95-octane gasoline may result in incomplete combustion, leading to waste as unburned fuel exits through the exhaust. Therefore, the Geely Xingyue is better suited for 92-octane gasoline. Differences between 92-octane and 95-octane gasoline: The main differences between 95-octane and 92-octane gasoline lie in compression ratio requirements, octane ratings, and pricing. The composition of n-heptane and isooctane varies between the two: 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane.
As a veteran driver who's been driving the Xingyue for several years, I think using 92-octane gasoline is perfectly suitable, as the manual also recommends. For urban SUVs like the Xingyue, the engine is designed with daily commuting in mind, and 92-octane offers great cost-effectiveness. Typically, a full tank can cover around 400-500 kilometers, making it both economical and practical. Don’t fall for rumors suggesting 95-octane is better—using the correct fuel grade minimizes engine wear, prevents carbon buildup, and extends engine life. When driving, the power delivery remains smooth and steady, and adding some fuel additives for maintenance can save a lot of hassle. Of course, always fill up at reputable gas stations, as off-brand fuel might trigger the engine warning light. Regular checks on the fuel pump and throttle are also crucial. After all, safe driving is what matters most.
