Can the Jetta VS7 use 92 octane gasoline?

[BraxtonAnn]

Jetta VS7 can use 92 octane gasoline, but using 95 octane gasoline provides better engine protection. Even high-compression ratio engines can use lower octane gasoline, but you shouldn't choose gasoline solely based on compression ratio. Always follow the manufacturer's recommendations. Here's some information about 95 and 92 octane gasoline: 95 octane gasoline contains 95% isooctane and 3% n-heptane. High-compression engines should use high-octane gasoline. Using low-octane gasoline in high-compression engines may cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced power output, making it more suitable for premium vehicles. 92 octane gasoline contains 92% isooctane and 8% n-heptane, making it more suitable for mid-range vehicles.
