Should turbocharged cars use 92 or 95 octane gasoline?

[LaCollin]

Turbocharged cars should use 95 octane gasoline. The differences between 95 octane and 92 octane gasoline are as follows: 1. 92 octane gasoline contains approximately 92% isooctane. 2. 95 octane gasoline contains approximately 95% isooctane. 4. 92 octane gasoline contains approximately 8% n-heptane. 5. 95 octane gasoline contains approximately 5% n-heptane. 6. Isooctane has better anti-knock properties, while n-heptane has poorer anti-knock properties. Therefore, the higher the octane rating, the higher the octane number, indicating better anti-knock performance of the gasoline.
