Can the Lavida 1.4T use 92 octane gasoline?
2 Answers
Lavida can use 92 octane gasoline. Below is relevant information about vehicle refueling: Methods for checking gasoline selection: The label on the inner side of the fuel tank cover lists the suitable fuel grades for your purchased vehicle. This label typically displays multiple fuel grades - the higher the grade number, the greater the octane rating and anti-knock performance. The first listed grade is the recommended priority fuel choice, followed by other national standard fuel grades. Differences between fuel grades: They have different octane ratings. 98 octane gasoline is a mixture of 98% isooctane and 2% n-heptane; 95 octane gasoline consists of 95% isooctane and 5% n-heptane.
I've been using the Lavida 1.4T for four years and always refuel with 95-octane gasoline as required by the manual. This engine is turbocharged with a high compression ratio, requiring high-octane fuel to prevent knocking issues. Knocking refers to abnormal combustion, which sounds like metal knocking noises and may damage internal engine components. Once when I returned to my hometown, the gas station only had 92-octane fuel, so I temporarily filled half a tank. While driving, I felt the acceleration wasn't as smooth, and there was slight shaking. I quickly used it up and switched back to 95-octane, and the car immediately returned to normal. Using 92-octane occasionally in emergencies is acceptable, but long-term use can lead to increased carbon deposits, higher fuel consumption, and even trigger the engine light. I recommend checking your user manual, which clearly states the recommendation for 95-octane. For the longevity and peace of mind of your vehicle, stick to 95-octane and choose reputable gas stations to ensure fuel purity, making your driving experience more reassuring.
