What Type of Cars is 98 Octane Gasoline Suitable For?

[ZoeyFitz]

98 octane gasoline is suitable for cars with an engine compression ratio above 10. It is composed of 98% isooctane and 2% n-heptane. The gasoline octane rating represents the ratio of the actual gasoline's anti-knock performance to that of standard gasoline, with higher ratings indicating stronger anti-knock properties. The octane number of gasoline is a unit that measures its anti-knock performance under lean mixture conditions, numerically equal to the volume percentage of isooctane in the standard fuel that matches the anti-knock performance of the sample under specified conditions. The standard fuel consists of a mixture of isooctane and n-heptane: 1. Isooctane is used as a standard for excellent anti-knock performance, with an octane number set at 100; 2. N-heptane is used as a standard for poor anti-knock performance, with an octane number of 0, representing the tendency to cause knocking in gasoline engines.
