Should the Volkswagen Lavida use 92 or 95 octane fuel?
1 Answers
Lavida's factory-recommended fuel grade is 92 octane. It is advisable to follow the manufacturer's requirements. Generally, 92 octane gasoline is suitable for gasoline-powered vehicles with an engine compression ratio between 8.6-9.9, while 95 octane gasoline is suitable for those with a compression ratio between 10.0-11.5. Key energy-saving indicator: The primary criterion for selecting gasoline grade is the engine's compression ratio, which is also the core energy-saving indicator in modern vehicles. Impact of compression ratio: The higher the compression ratio of an engine, the smaller the volume of combustible mixture is compressed, resulting in greater power and lower fuel consumption. Engines with higher compression ratios require gasoline with higher anti-knock properties, meaning a higher octane rating.
