Can 92 and 95 gasoline be mixed in Lavida?
2 Answers
Lavida can mix 92 and 95 gasoline, but it is not recommended. Long-term mixed use may cause knocking, insufficient power, and other situations. Especially for cars that use 95 gasoline, long-term use of 92 gasoline will increase the frequency of knocking and aggravate engine wear. The following are the differences between 92 and 95 gasoline and how to check the gasoline grade: Differences between 92 and 95 gasoline: The anti-knock properties are different. The gasoline grade represents the anti-knock property, and the higher the grade, the better the anti-knock ability. The isooctane content is different. 92 gasoline is composed of 92% isooctane and 8% n-heptane, while 95 gasoline is composed of 95% isooctane and 5% n-heptane. The reason why 95 gasoline is slightly more expensive is that the proportion of isooctane is higher. How to check the gasoline grade: Refer to the car manual, which will record the recommended gasoline grade. The gasoline grade will also be indicated on the fuel tank cap, recommending which gasoline grade to use and which is the best.
Last time I fueled my Lavida, I impulsively mixed 92 and 95 octane gasoline. The car immediately lost power and made a buzzing noise. My mechanic friend told me the Lavida's engine is designed for 95 octane high-octane fuel. Mixing with 92 lowers the octane rating, increasing the risk of engine knocking and damage. The manual strongly recommends 95 octane. While saving money with 92 is fine short-term, long-term mixed fueling leads to more carbon deposits, higher fuel consumption, and even repair costs several times higher. Now I strictly use 95 octane for peace of mind. During long trips when 95 isn't available, emergency mixing is acceptable, but switch back to pure 95 after that tank. Car maintenance requires attention to detail.
