With the rapid economic growth of the mainland, people's living standards have also been greatly improved, and cars have also entered thousands of families and become daily travel tools. Because buying a car is no longer a new thing, the maintenance of the car after buying a car is a problem that the Chinese people are more concerned about.
Nowadays, the price of gasoline in the mainland is also rising, and the daily refueling cost of fuel vehicles is also gradually increasing. So that many car lovers, came up with a variety of car tips. On the Internet, it was announced that the manufacturer designated the model with No. 92 gasoline plus No. 95 gasoline, and after three months of comparison, three significant changes were found.
1, the number of kilometers to run is more.
2, the engine shake is obviously smaller, the sound is also smaller.
3, start to accelerate the climb, feel the power becomes greater.
In the comments, many riders also said that there have been similar situations. Some car owners also said that they were a 13-year-old car, the on-line detection of exhaust gas did not pass, the owner added a box of No. 95 gasoline to run a lap back, the on-line test actually passed. Are these phenomena that netizens say are this? Is No. 95 gasoline really that magical?
The higher the label, the higher the price of gasoline and the higher the quality of gasoline, which is a common sense error. In fact, gasoline comes out of the same tubing, and the only difference is the proportion of isooctane. The isooctane ratio of No. 92 gasoline is 92%, and the proportion of No. 95 gasoline is 95%.
The higher the proportion of isooctane, the more stable it is in a high temperature environment, and the stronger the explosion resistance! It has a certain effect on the protection of the engine. The compression ratio of different engine models is not the same, and the higher the compression ratio, the higher the gasoline corresponding to the high grade is required, in order to reduce the knock.
Mid-to-high-end models need to be filled with gasoline above No. 95 because it reduces knock and protects the engine, because most of these models use turbocharged engines.
Through the understanding of the above common sense knowledge, we can know that the label of gasoline does not represent the quality of oil. For the 3 significant changes proposed by the above netizens, let's analyze them.
1, the number of kilometers to run is more
This problem should be that different models have different data, No. 95 gasoline knock reduction, help to burn, the stronger the power, running high-speed turbocharged models plus No. 95 gasoline than No. 92 gasoline is resistant to burning, running more than tens of kilometers is normal.
If you use a naturally aspirated Japanese model in the urban area, adding No. 95 gasoline will not go as far as No. 92 gasoline.
2, the engine is obviously less shaky, the sound becomes smaller, and the power seems to become stronger
This situation is also what happens to some models and is not representative of all models. Some models are in the middle of engine compression, such models, although the manufacturer labels the addition of No. 92 gasoline, in fact, add No. 92 gasoline and No. 95 gasoline can also be. Since the No. 95 gasoline knock phenomenon does have a small relief, the engine jitter is reduced. But this effect is so small that it is almost imperceptible.
3, the old car plus No. 95 gasoline, passed the exhaust gas test, is this true?
This situation is also a very special case. Because the old car has been loaded with No. 92 gasoline, the back is filled with No. 95 gasoline, and before refueling, add fuel cleaner, and then add No. 95 gasoline to run at high speed, which will make the engine run at high speed, plus part of the role of fuel cleaner, can reduce the carbon deposit of the engine, and combustion is more fully conducive to improving emissions. As a result, the exhaust gas detection can be passed.
Other phenomena to be aware of in daily refueling:
1, the same number of gasoline three gas stations can be mixed, but try not to mix with the same number of gasoline of small gas stations. Because the gasoline oil in small gas stations is uneven, it is easy to affect the engine.
2, in accordance with the factory manufacturers regulations refueling, manufacturers designated No. 92 gasoline can be added No. 95 gasoline, manufacturers designated No. 95 gasoline try not to add No. 92 gasoline, occasionally add error is no need to worry, if the long-term wrong will produce certain wear on the engine.
3, the manufacturer designated to add No. 92 gasoline models, plus No. 95 gasoline, may lead to insufficient combustion, increase the carbon deposition of the engine, serious cause engine shaking obviously, noise and other issues. Not only does it not protect the car engine, but it also wastes money and is not worth the loss.
With the increase in the number of cars in the mainland, more and more families have entered the family of cars, so for the maintenance of cars is also paid special attention, according to the factory designated oil refueling is the most correct refueling method, if the long-term use of high-grade cars, but there is a snake to add enough practices.
