Is it better to use 92 or 95 octane gasoline for the Golf?

[DiMia]

Different types of engines require different grades of fuel. The Golf 1.6L naturally aspirated engine version is suitable for 92 octane gasoline, while the TSI turbocharged engine models are suitable for 95 octane gasoline. Below are the differences between 92 and 95 octane gasoline and the basic methods for selecting fuel: 1. The main difference between 92 and 95 octane gasoline lies in the composition of heptane and isooctane. 92 octane gasoline contains 92% isooctane and 8% heptane, while 95 octane gasoline contains 95% isooctane and 5% heptane. 2. The label on the inside of the fuel tank cover lists the recommended fuel grade for your vehicle. The higher the octane number, the greater the octane value and the better the anti-knock performance. The first listed is the preferred recommended fuel grade, followed by other national standard fuel grades, which should only be used when the recommended grade is unavailable and for short-distance driving only. 3. Using the recommended fuel grade ensures optimal engine performance, reduces fuel consumption, and extends the engine's lifespan.
