sure. Because the anti knock performance of 95 is better than that of 92, the use of 95 on 92 model has no impact on the car, just a little waste of money.
Gasoline is composed of isooctane and n-heptane. No. 92 gasoline represents 92% isooctane and 8% n-heptane; 95 # gasoline represents 95% isooctane and 5% n-heptane.
92 and 95 refer to the grade of gasoline, which represents the antiknock property of gasoline and has nothing to do with the quality of gasoline. The two kinds of gasoline have the same composition but different proportions. The result is that the antiknock property and combustion speed are different.
Isooctane has very good antiknock property, but its flame propagation speed is very slow; The antiknock property of n-heptane is extremely poor, but the flame propagation speed is extremely fast. Therefore, No. 92 gasoline has weak antiknock property and fast combustion speed; 95 # gasoline has high antiknock property and slow combustion speed.
In theory, 95 gasoline is more durable than 92 gasoline, which will save money correspondingly. But in fact, 95 gasoline itself is about 1 yuan more expensive than 92 gasoline, so the fuel cost per kilometer is about the same.
Therefore, in general, when selecting gasoline, the engine can burn safely as long as it meets the minimum gasoline grade requirements. But for cars with 95 # gasoline, you must not add 92 # gasoline, otherwise it will easily cause knock in the cylinder.
