What does the gasoline label mean
When I go to the gas station to fill up, I often hear employees ask what number of gasoline to add, and the number here refers to the number of gasoline.
The gasoline label is the ratio of the knock resistance of the actual gasoline to the knock resistance of the standard gasoline, the higher the label, the stronger the knock resistance. In the past, the gasoline labels were 90, 93, and 97, but since the introduction of the unified Supply country Five standard, the gasoline labels have been changed to the current 89, 92, 95, and 98.
Number 93 is 92 or 95
Under the National five standard, the automobile emission standards are more stringent, and the old label is not enough to meet the new emission standards, so the gasoline label has also been changed, and the friends who originally added 93 gasoline are now generally added 92 gasoline.
Three, what is the number of 97 gasoline
Under the national five standard, the original model with 97 gasoline is now generally 95 gasoline, and some of the better performance can also be changed to 98 gasoline. The 95 gasoline used today will be more environmentally friendly and cleaner than the 97 gasoline. However, after the 97 to 95, the average fuel consumption increased by 0.37%, that is, each car with 60 liters of oil, need to consume 0.2 liters more, but the actual change is little.
Four, why is no. 90 gasoline gone
The national five standard gasoline will be more environmentally friendly, and the quality of the new standard oil will also be improved, and the original 90 gasoline will be changed to 89 gasoline; With the continuous development of China's automobile industry, the gasoline cars in the society are generally based on 92 and 95 gasoline, and there are few cars with 89, so basically the gas station can not see the 89 gasoline.
