Which Cars Use 98 Octane Gasoline?

[MacNoah]

Vehicles that use 98 octane gasoline are those with an engine compression ratio of 10 or higher, or cars whose fuel tank specifies the use of 98 octane gasoline. 98 octane gasoline refers to gasoline with an octane rating equivalent to a mixture of 98% isooctane and 2% n-heptane. Gasoline is a volatile, flammable liquid hydrocarbon mixture distilled or cracked from petroleum, primarily used as fuel for spark-ignited internal combustion engines. It mainly consists of organic compounds obtained from crude oil distillation and various additives. The octane rating of gasoline measures the anti-knock properties of a specific gasoline mixture (which can cause knocking and reduce the efficiency of reciprocating engines).
