What Octane Gasoline Should the Sylphy Use?
2 Answers
Sylphy should use 92 octane gasoline. The grade of gasoline is classified by its octane rating. For example, 97 octane gasoline refers to a fuel with anti-knock performance equivalent to a mixture of 97% isooctane and 3% n-heptane. The higher the octane number, the better the anti-knock performance. The choice of gasoline grade should be based on the engine's compression ratio, which is specified in each vehicle's user manual. Gasoline is produced and sold according to its grade, with specifications defined by national gasoline product standards and related to different standards. Currently, gasoline grades available on the market include 90, 93, 97, 92, etc. These numbers are unrelated to the cleanliness of the gasoline.
The Sylphy owner's manual clearly states that it is recommended to use 92 or 95 octane gasoline. I prefer to use 92 octane because it is sufficient. My car has been running for five years, commuting daily in the city, with fuel consumption maintained at around 6-7 liters per 100 kilometers. It is slightly more fuel-efficient during long highway trips, and the performance has been stable without any issues. Some people believe that 95 octane gasoline provides slightly better power, but it is significantly more expensive, adding tens of dollars to monthly fuel costs, which is not cost-effective. The key is to choose reputable gas stations and avoid low-quality fuel to prevent carbon buildup or engine damage. During maintenance, check the spark plugs and fuel system, as regular upkeep can improve fuel efficiency. There is no difference in refueling under different regional climates; the car starts reliably in both cold and hot weather. Remember, following the manual is the safest approach—don't listen to random advice that wastes money. Simply put, 92 octane is more than enough, being both economical and practical.
