Should the Lifan KPV150 use 92 or 95 octane gasoline?

[DelParker]

Lifan KPV150 uses 92 octane gasoline. The differences between 92 and 95 octane gasoline are as follows: Content differences: There is no quality gap between 92 and 95 octane gasoline, only differences in composition. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. The higher the isooctane ratio, the better the anti-knock performance. However, each car engine has different performance parameters, resulting in different anti-knock requirements. The appropriate gasoline type should be selected based on the anti-knock data provided by the manufacturer. Price differences: The higher the isooctane content, the more expensive the price, so 95 octane gasoline is slightly more expensive than 92 octane. Power differences: Engines with high compression ratios should choose gasoline with high octane values. This is because high engine speeds cause earlier ignition in the cylinder. When the speed reaches a peak, the gasoline in the cylinder may combust prematurely before ignition occurs, which is called knocking. Gasoline with higher octane content can more effectively enhance anti-knock performance.
