Consequences of Using 92 Octane Gasoline in a Golf?

[AmeliaMarie]

Using 92 octane gasoline in a Golf may lead to engine shaking, lack of power, and the illumination of the emission light. Below is an introduction regarding the suitable gasoline types for the Golf: 1. Gasoline Usage Recommendation: It is advised to use 95 octane or higher fuel. The appropriate fuel grade for your car primarily depends on its compression ratio. For turbocharged engines, it is generally better to use higher-grade fuel. Different gasoline grades are formulated to meet the requirements of engines with varying compression ratios. Engines with a compression ratio greater than 9:1 should use 90 octane or higher, those above 9.5:1 should use 92 octane or higher, and those exceeding 10:1 should ideally use 95 octane or higher. Many high-compression ratio vehicles have fuel tank labels recommending 92 octane or higher. 2. Disadvantages of Using Lower Octane Fuel: Although lower octane fuel can be used, it is only the minimum standard and barely acceptable. Any slight deviation in fuel quality will immediately reveal issues, causing the engine to shake, lose power, and trigger the emission light. Therefore, when your car is labeled for 92 octane or higher, although higher octane does not necessarily mean better quality than lower octane, it is recommended to use the higher octane to ensure stable engine operation and optimal combustion, reduce carbon deposits and collisions between moving parts, and protect the oxygen sensor. In high-compression ratio engines, using higher octane fuel during steady driving can significantly improve fuel efficiency and extend driving range. No matter how advanced the car is, it cannot change the engine's compression ratio or cylinder stroke. Lower octane fuel can be used in high-compression ratio engines but is not optimal. To prevent knocking, some loss in power and performance is inevitable.
