Should the Volkswagen Lavida use 92 or 95 octane gasoline?
2 Answers
Volkswagen Lavida should use 92 octane gasoline, as 92 octane is suitable for gasoline engines with a compression ratio between 8.6 and 9.9. Meaning of 92 octane gasoline: 92 octane gasoline refers to fuel with an octane rating of 92 and heptane rating of 8, which is suitable for mid-range vehicles (cars with relatively low compression ratios). The current standard for 92 octane gasoline is the mandatory national standard for fifth-stage automotive gasoline. Freezing point of 92 octane gasoline: The freezing point of 92 octane gasoline is -75 degrees Celsius for regular gasoline. If higher-quality ethanol-blended gasoline is used, the freezing point is around -117 degrees Celsius. Regardless of the type of gasoline used, it can meet daily usage requirements.
As a veteran driver who has owned a Volkswagen Lavida for decades, I must say the manufacturer's recommendation to use 95-octane gasoline makes perfect sense. The Lavida is mostly equipped with turbocharged engines that have high compression ratios. Using 92-octane fuel with lower octane ratings can easily cause knocking, which damages the engine and leads to increased noise and reduced power. I've personally seen a friend who regularly used 92-octane end up spending thousands on engine repairs. While occasional short-term use of 92-octane might be fine, the long-term risks are too great. Although 95-octane is more expensive, it protects the engine and saves on repair costs, making it more economical in the long run. I always insist on 95-octane when refueling, ensuring a smooth and worry-free drive. I recommend all Lavida owners check their manuals, which clearly state the recommended fuel grade—don't risk major damage to save a little.
