The difference between 97 and 95 gasoline is the national five standard gasoline, and the 97 is the national four standard gasoline, which was originally 97 gasoline, and the anti-knock resistance of the 95 gasoline is higher than that of the 95 gasoline after the gasoline is upgraded and changed.
The octane content of gasoline is higher than that of gasoline No. 95 The combustion of gasoline emits fewer pollutants than gasoline No. 97.
What is the difference between 92 gasoline and 98 gasoline? The octane number of gasoline with different grades is not the same, the higher the octane number of gasoline with the higher the rating, and the higher the octane number, the better the stability of gasoline. Many turbocharged and high-performance engines basically need to use high-grade gasoline to avoid knocking in the engine.
Knocking is an abnormal combustion phenomenon in the engine, which will affect the power output and fuel rationality of the engine. Severe knocking can even damage the engine. Detonation occurs during the compression stroke, when the engine is in the compression stroke, the intake and exhaust valves of the engine are basically closed, and the engine's pistons run upwards to compress the combustible mixture.
When compressed, the temperature and pressure of a compressed combustible mixture will basically increase. If the stability of the gasoline is not good, the combustible mixture will be burned in advance, and the burning combustible mixture will push the piston downward, and the piston is running upwards at this time, which will affect the power output of the engine. Severe knocking can even affect the piston and connecting rod deformation of the engine.
If the engine is damaged to this extent, the cost of repairing it is very high. Of course, friends must choose accurate gasoline for their cars when they usually use the car, and they must go to the gas station with better oil products to refuel. Friends must not be greedy for cheap to go to some gas stations with poor oil quality to refuel.

In China, household gasoline cars are basically filled with gasoline from spring liquid. Many people don't know what exactly is the difference between 95 and 97 gasoline? Which one is better to add gasoline to a car? How to choose?
The differences between 97 and 95 gasoline are as follows:
1. The composition of gasoline is different
The label of gasoline is calibrated according to the content of isooctane and n-heptane in the composition of gasoline, the higher the label, the higher its isooctane content, so the isooctane content of gasoline 97 is higher than that of gasoline 95.
2. The quality of gasoline is different
The quality of gasoline mainly depends on its anti-knock performance, and the anti-knock resistance is related to the content of octane, the higher the octane number, the better the anti-knock performance of gasoline, so the anti-knock performance of No. 97 gasoline is higher than that of No. 95 gasoline.
3. Different environmental protection angles
No. 95 gasoline is the gasoline refined according to the fifth stage standard after the state implements the fifth stage emission standard, so the combustion of No. 95 gasoline emits fewer pollutants than No. 97 gasoline.
4. The matching engine is different
The higher the fuel grade, the higher the compression ratio of the matching engine, so the higher the power of the car, so if the original car with 97 gasoline is switched to 95 gasoline, it will inevitably lose some power.
5. The relationship between the two is different
No. 95 is the national five standard gasoline, No. 97 is the national four standard sail gasoline, and the original No. 97 gasoline is 95 gasoline after further processing according to the national five standard.
That's itThe difference between 97 and 95 gasolineNo. 95 implements the national standard, which is more environmentally friendly, while No. 97 implements the national standard. At present, the state is vigorously promoting national gasoline, and it is believed that the national standard gasoline will be eliminated soon!

No. 95 gasoline and No. 98 gasoline are both high-grade gasoline. Compared with No. 95 gasoline, the research octane number of No. 98 gasoline is 3 octane units higher than that of No. 95 gasoline, and it is technically difficult to increase the octane number of unleaded gasoline for vehicles by one unit, and the processing cost of input is high. As a result, high-grade gasoline sells for a bit more than regular gasoline.
The main characteristics of the high-end car are high power, high compression ratio, large displacement, and the compression ratio of the car above or 10 must use unleaded gasoline for high-grade vehicles above 92, otherwise, the car will produce detonation and cause engine damage in serious cases. For high-end cars with a compression ratio of 10 or more, it is better to use high-grade 98 gasoline than 95 gasoline.
The gasoline engine with the above compression ratio should use 95 gasoline. The gasoline engine with the compression ratio above should be 98.
98 petrol is suitable for high-end luxury cars and high-horsepower sports cars. Compared with No. 92 and No. 95 gasoline, the production of No. 98 gasoline will have higher requirements for technology and equipment, and China has only realized the domestic production of this brand gasoline in the past two years. The anti-knock socks of No. 98 gasoline are undoubtedly the best of the three gasoline, and at the same time have the highest production standards.
Gasoline 95 is suitable for the vast majority of cars. No. 95 gasoline is generally suitable for turbocharging and models with high compression ratio, and it can be compatible with the vast majority of models on the market, whether it is a small car of tens of thousands of yuan or a high-end car of hundreds of thousands.

95 means 95 gasoline and 98 means 98 gasoline. The gasoline designation represents the octane number of the gasoline. Car lovers on the web often say this.
The isooctane ratio of No. 95 gasoline accounts for about 95%, and the proportion of n-heptane accounts for about 5%. Because the anti-knock resistance of isooctane is better, and the anti-knock resistance of n-heptane is poor, the higher the label, the higher the octane number, the better the anti-knock resistance of gasoline. By analogy, No. 98 gasoline is more anti-knockout.
About Internet Terminology:

Meaning of Gasoline Label:
The gasoline index index index indicates the octane number of gasoline, and gasoline 98 represents gasoline with 98% isooctane and 2% n-heptane. No. 95 gasoline stands for 95% isooctane, 5% n-heptane gasoline. The higher the designation, the higher the octane number, which means that the gasoline has better anti-knock performance.
When using motor gasoline, improper fuel flow into the fuel system may damage the fuel system and engine; Do not use gasoline containing methanol or alcohol; Do not splash fuel on the paint surface to avoid damaging the paint surface; If the ice around the tank door won't open, nudge or tap the tank door to remove the ice and open the tank door.
