You can't drive a new car for another five years if you add 95% to it.
95 engine oil will not be cleaner and will not help the engine life.
Poor oil filling will really affect the life of the engine.
Ye of SAIC-GM-Wuling Automobile Co., Ltd. published a paper in China New Technology and New Products magazine, and analyzed the influencing factors of engine cleanliness and its control measures.
It says: too many impurities in the engine and poor cleanliness will increase the wear and tear of the engine during operation and affect its life.
Kind of like what? We rub our faces with facial cleanser, which is quite comfortable, but if we put iron sand in facial cleanser, we will bleed after rubbing our faces.
It is also said that the fuel impurity is a very important factor affecting the cleanliness of the engine, that is, "the oil is not clean" in the vernacular.
However, we have talked about it many times in previous videos. The main difference between 92 and 95 is the octane number.
No.95 gasoline has higher octane number and stronger antiknock ability. As for the cleanliness of gasoline itself, it has nothing to do with whether the label is 92 or 95.
Even if you keep filling 95 gasoline, you won't say it's cleaner than 92. It's a bit like: my stomach is uncomfortable, and I want to buy some health care products to recuperate.
As a result, I bought a vitamin C and a vitamin B, both of which were wrong and the conditioning direction was wrong.
But you can get a better experience.
Although it is impossible to make the car live for a few more years by adding 95, or it is called "driving for a few more years", it is still possible to make the car drive better in the past few years.
Zuo Zinong of xihua university Institute of Transportation and Automotive Engineering and Mai Huazhi of China Automotive Technology Research Center published papers in Journal of xihua university (Natural Science Edition).
"Study on the Influence of Different Octane Numbers of Gasoline on Turbocharged Direct Injection Gasoline Engine" refers to an experiment with a 1 1.6L self-priming vehicle.
It is found that the use of high octane gasoline can increase the torque by 4.07% around 2000 rpm, and improve the fuel economy.
To put it simply: when commuting in the city, we feel more energetic and the torque has increased by 4%. Some friends can still feel it. It is unrealistic to feel it all. After all, it is only 4%.
We had shredded potato bibimbap at noon yesterday, didn't we? I changed my pork belly bibimbap today.
After eating, I feel that the way to move bricks in the afternoon may be a little different. They are all called "full". After all, the food is still different, right?
The 92-year-old car has been increased by 95, which may last for five years.
If the new car of 92 keeps adding 95, it is impossible to drive for another 5 years. There is no such thing.
However, if you think about it, the power of the car in 1992 is really getting worse year by year, and the car is really old. At this time, if you add 95,92 to 95, you may feel the second spring.
Psychologically, I feel that my car can fight for another five years. Actually, it's about the same.
You might as well listen to Yang Qi's master's thesis "Research on Control and Evaluation Method of Engine Carbon Deposition", which says that about 68% of cars will produce different degrees of carbon deposition after driving 30,000 km.
With the increase of service life, it will become more and more serious, leading to increased fuel consumption, excessive acceleration, unstable idle speed and so on.
Moreover, too much carbon deposition will also increase the compression ratio of the engine, which is prone to deflagration. How to understand this matter?
For example, the volume of a single combustion chamber of a 1.6L four-cylinder engine is 400ml, so when the piston moves to the highest point, the volume of the combustion chamber is compressed to 40ml.
The compression ratio of this engine is 400:40, which is our legendary "10: 1", right?
At this time, carbon deposits in the combustion chamber occupy the space inside the combustion chamber, for example, 3ml, so the compression ratio becomes 397:37.
3ml is blocked by carbon deposit, not air, but carbon deposit, and the compression ratio will become 10.7: 1, and the compression ratio will become larger, which may lead to new problems.
Listen to the above-mentioned paper "Study on the Influence of EGR on the Performance and Knock of Small Intensified Gasoline Engines with Different Fuels" by Dr. Pan Mingzhang of Tianjin University.
After the compression ratio increases, the initial temperature and pressure of the mixture will increase, but before the spark plug is ignited, it is easy to spontaneously ignite, and a pressure wave will oscillate in the cylinder, resulting in knocking and energy loss.
At this time, replacing easy-to-ignite 92 # gasoline with 95 # gasoline, which is difficult to ignite, can really alleviate the influence of carbon deposition to a certain extent, so as to restore the car to a certain state.
Psychologically, I will feel that it is ok to drive for a few more years.
However, the problem of old cars appears in all aspects. "Improving the gasoline label" can only solve the problem of engine carbon deposition, and chassis, gearbox and so on may affect the car experience.
When you are older, it may be all kinds of high 3, which is aimed at hyperlipidemia. If you don't care about hyperglycemia and hypertension, there may be problems, right? The body is still in a sub-health state.
You can't drive a new car for five years if you add more than 95.
So in general, 92' s new car adds 95, except that it will be more refreshing to drive, and this kind of coolness varies from person to person, and some people still don't notice it.
It can't make a 95-year-old car last five years longer than a 92-year-old car. It's just psychological and experiential.
The power of 92 classic cars began to decline a little, and it was caused by carbon deposition, which was also ignored. At this time, adding 95% oil can really restore some power and rejuvenate the second spring.
It is a psychological feeling whether you can drive for five more years, because the car condition feels better and the actual service life is the same.
