Does the car need to be emptied when the No. 95 oil is replaced with the No. 92 fuel tank?

There are some 95 in it, but the 95 and 92 mixtures are also used.

To be emptied. Although the base oil used in 92 and 95 gasoline is the same, the proportion of their antiknock agent is different, and if it is mixed, it will cause engine knocking, insufficient power, carbon deposits, etc. In addition, if the No. 95 oil is replaced with No. 92 oil, it is necessary to pay attention to whether the car can use No. 92 gasoline, otherwise it may cause damage to the car engine and have an impact on the power of the car.

The base oil used in 92 and 95 gasoline is the same, and there is no difference in oil quality, the only difference is the proportion of antiknock agent, that is, the octane number content in gasoline.

Extended information: In the case of the same amount of gasoline 92 and 95, there is no significant difference in the quality of the sediment produced by the two grades of gasoline, which indicates that the carbon deposits produced by high-grade gasoline are not less than those produced by low-grade gasoline, that is, the marking of gasoline has nothing to do with the quality, cleanliness and quality of gasoline, and the only difference between them is anti-knock performance. It is necessary to deliberately pursue high-grade gasoline, as long as you add the corresponding number to the regular gas station according to the instructions or the prompts on the fuel tank cover, because this is the fuel label finally determined by the manufacturer according to the needs of China's oil and road conditions.

Hello friend, no, just add it directly.

To be emptied.

Although it is said that 92 and 95 gasoline.

The base oil they use is the same, but the proportion of their antiknock agent is different, if mixed with Hu or Qiao, it will cause engine knocking, insufficient power, carbon deposition and so on. In addition, if the 95 oil is replaced with 92 oil, it is necessary to pay attention to whether the car can use 92 gasoline, otherwise it may have an impact on the car engine.

causes damage to the power of the car.

Influential. The base oil used in 92 and 95 gasoline is the same, and there is no difference in oil quality, the only difference is the proportion of antiknock agent, that is, the octane number in gasoline.

The level of content.

The car selects the gasoline marking.

The first criterion is the compression ratio of the engine.

It is also the core energy-saving index of contemporary automobiles. The operation of the engine is composed of the repeated movements of the cylinder "suction-compression-combustion-exhaust-suction", and the ratio of the cylinder volume of the piston at the farthest point of the stroke to the nearest point is the compression ratio of the trouser button.

The least costly and most effective way to reduce fuel consumption is to increase the compression ratio of the engine. Increasing the compression ratio only changes the piston stroke, and the more the mixed oil and gas are compressed, the greater the reaction to its combustion, and the more fully it burns.

However, the compression ratio is not easy to move, because there is another index to cooperate, that is, the anti-knock index of the steam ridge oil, also known as the octane number, that is, the gasoline label.

Hello <> Senqing

Yes, if you want to change gasoline from 95 to 92, follow these steps:1Before adding 92 new gasoline, use up or empty all the gasoline oil in the fuel tank, so as to ensure that the new 92 gasoline is completely mixed with 95 gasoline, and there will be no unstable quality.

2.If you still have a certain amount of 95 petrol in the tank, you can add a few litres of 92 petrol and then refill this 92 petrol again after a few kilometers, so that the mixture is gradual and you can avoid wasting the remaining high-quality petrol. However, it should be noted that there may be some changes in the power and fuel consumption of the car during the transition period, and you need to pay attention to adjustments.

In general, in order to ensure the quality and safety of the vehicle, it is recommended to empty the fuel tank as much as possible before adding other qualities of gasoline.
