Should the Lavida 1.4T use 92 or 95 octane gasoline?

Lavida 1.4T should use 95 octane gasoline. Fueling precautions: 1. Use automotive gasoline only; improper fuel entering the fuel system may damage the fuel system and engine. 2. Do not use gasoline containing methanol or alcohol. 3. Avoid spilling fuel on painted surfaces to prevent paint damage. 4. If the fuel tank door is frozen and cannot be opened, gently push or tap the door to remove ice and open it. 5. Prevent excessive fuel pressure that may cause spraying. 6. Insert the fuel nozzle deep into the tank to avoid fuel overflow or spillage, which could lead to fire and explosion. 7. Before opening the fuel filler cap or touching the fuel nozzle, touch the car body to discharge static electricity. Do not re-enter the vehicle during refueling to prevent static electricity buildup.
As a Lavida 1.4T owner, I believe using 95-octane fuel is more reliable. This car has a turbocharged engine which is prone to knocking under high pressure. 95-octane fuel has a higher octane rating, reducing such issues and making the engine run smoother with more responsive acceleration. It also minimizes vibration during highway driving. Although 92-octane fuel is cheaper, long-term use may affect engine lifespan and even waste fuel—mileage per liter could drop by 5%-10%. My real-world tests show 95-octane actually improves fuel efficiency, making the total cost difference negligible. Volkswagen's manual also recommends 95-octane. I suggest following the standard—don’t sacrifice performance and safety for minor savings, especially since knocking is worse in stop-and-go traffic.
