As for the issue of gasoline labels, in fact, many car owners, especially new car owners, always have misunderstandings, thinking that the gasoline label represents the quality and purity of gasoline, so they feel that adding 95 gasoline is safer than adding gasoline. good. ?92 gasoline. In fact, these different gasoline labels only represent different anti-knock properties of gasoline. Gasoline is composed of isooctane and n-heptane. The meaning of No. 92 gasoline is that the isooctane content in the gasoline is 92%. Likewise, 95-octane gasoline means 95% isooctane. The content of isooctane determines the anti-knock properties of gasoline, so the anti-knock properties of No. 95 gasoline are better than those of No. 92 gasoline. As long as you're at a regular gas station, the only difference between these two different gasolines is their ability to resist knocking.

Why do some people think that after a car changes from No. 92 engine oil to No. 95 engine oil, the sound of the engine becomes smaller and the power seems to become stronger? In fact, this is not to say that premium gasoline can enhance the power of the vehicle. It's just that the anti-knock performance of the 92-number gasoline used initially was very weak, and it encountered engines with high compression ratios. It may begin to burn before igniting the spark point, causing knocking. , thus affecting the power of the engine. Regardless of the engine, would it be better to use premium gasoline? Not really. Due to the high ignition point of high-grade gasoline, delayed combustion may occur when used in vehicles with low-compression ratio engines, resulting in incomplete combustion of the gasoline, which is also detrimental to the engine.

Therefore, when choosing a gasoline label, it should be used according to the actual needs of the engine. For small displacement and low compression ratio engines, choose 92 gasoline. For large displacement or turbocharged engines, choose 95 or 97 gasoline, so that you can truly get the best out of your vehicle. Generally speaking, the inside of the vehicle's fuel tank cap has a mark that can hold gasoline and a mark that recommends the use of gasoline. The owner can make selections based on this mark. When using car gasoline, in addition to choosing the correct label, I personally think the most important thing is to go to a regular gas station to refuel, and ensuring the quality of the oil is the most critical point.

Because 92 gasoline has weak knock resistance, its ignition angle needs to be delayed, resulting in faster fuel consumption in the car. However, because 95-octane gasoline has strong anti-knock properties, the car's fuel consumption is relatively slow. That's all the difference. No. 92 gasoline and No. 95 gasoline are the most common domestic fuel brands. Of course, the price of No. 92 gasoline is slightly lower than the price of No. 95 gasoline. No. 92 oil and No. 95 oil can be used in ordinary family cars. However, I recommend that you use a universal manual or a fuel tank cap marked No. 95, preferably No. 95, of course, it is not important to use it occasionally, don't worry about it.
