Where to Find 98 Octane Gasoline?
1 Answers
Due to the relatively low market penetration of 98 octane gasoline, it is generally more effective to call the customer service hotlines of Sinopec or PetroChina to inquire about fuel availability at nearby gas stations. Vehicles with engine compression ratios of 10 or higher should use 98 octane gasoline. 98 octane gasoline offers superior anti-knock performance and power output, while 95 octane gasoline has average anti-knock combustion capabilities. Gasoline is a transparent, flammable liquid refined from petroleum through processes such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components. After refining, it is blended with high-octane components and primarily used as fuel for spark-ignition internal combustion engines in automobiles. 98 octane gasoline refers to fuel whose octane rating equals a mixture of 98% isooctane and 2% n-heptane. The advantages of 98 octane gasoline can be summarized as 'two highs and two lows': higher anti-knock performance and power output, along with lower harmful substances in the gasoline and reduced exhaust emissions. Although 98 octane gasoline is high-quality, it is not suitable for all vehicles. Generally, vehicles with fuel tank caps labeled 'Please use 95 octane or higher gasoline' can use 98 octane gasoline. Additionally, vehicles with engine compression ratios of 10 or higher are also suitable. Car owners should avoid frequently switching between different gasoline grades; once a suitable fuel type is selected, it is best to consistently use the same gasoline for an extended period.
