Everyone is cheering，I definitely hear these communication with 90.93.97.98。In fact, 90.93.97.98 is the different types of gasoline，Different models are divided into different models according to different gasoline content。

The so -called No. 90 gasoline，is 90%of the isopharum，10%orthopatane。No. 93 gasoline is 93%of the isopharum，7%orthopatane。

Digital label represents the different content of the deleat value in the car。The octane value is the combustion Seabetindicator of gasoline，The higher the deleane value，The better its explosion resistance，The possibility of explosion of gasoline engine, the smaller the possibility of an explosion of the gasoline engine。

The primary criterion for car selection of gasoline marks is the compression ratio of the engine，It is also the core energy -saving indicator of contemporary cars。

The operation of the engine is composed of "inhalation -compression -combustion -exhaust -inhalation" of the cylinder，Pistons at the farthest point of the itinerary and the cylinder volume of the recent point is the compression ratio。

The best way to reduce fuel consumption cost is the best way to improve the compression ratio of the engine。Increasing compression ratio is just changing the piston itinerary，The more mixed oil and gas compress, the more powerful，The greater the reaction of its combustion，The more full the combustion。

But the compression ratio is not easy to move，Because there must be another indicator to cooperate，That is the anti -explosionality Seabetindicator of gasoline，Also known as deleane value，is the gasoline label。

Before using the vehicle，Should read the instruction manual carefully，Pay attention to the compression ratio。

Select No. 90 gasoline with a compressed ratio below 8.0,

The compression ratio between 8.0-8.5 is selected from 93 or 95 gasoline，

The compression ratio of 8.5-9.0 is selected from 95 or 97 gasoline，

The compression ratio is 97 or 98 gasoline，

Paper with a compressed ratio of 9.5-10.0 should be used for gasoline above 98
