Is 95 Octane Gasoline Mandatory for the Golf 1.4T?

[QuinnLynn]

According to official data, the Golf 1.4T model requires 95 octane gasoline. Reasons for using 95 octane gasoline: Since its engine is turbocharged, it demands a higher compression ratio. The compression ratios for 92 and 95 octane fuels differ significantly, as do their octane ratings and combustion speeds. 95 octane fuel better meets the needs of a turbocharged engine with a higher compression ratio. Risks of using lower octane gasoline: 95 octane gasoline consists of 95% isooctane and 3% n-heptane. High-compression engines should use high-octane fuel. Using low-octane fuel in a high-compression engine can lead to abnormal combustion, causing knocking, increased fuel consumption, and reduced driving performance.
