Choose a car, buy a car, use a car, come to Aika car! It is said that the car is the only purpose for me to come here, the release of this post is a kind of sharing! Moving fingers time flies, unwittingly phantom speed S7 has been my second car. Men-want to have a car of their own! No matter whether the car is a joint venture or a domestic brand, we only know that in 365 days of the year, no matter whether it is windy, rainy or sunny, the car is not only a means of transportation for us, but also after a hard day’s work or work. When we get into the car, we feel a harbor of comfort! Always feel that quietly locked in the car can not think about anything, palpitations can relax and clear the tiredness of the day, play a favorite CD to relax, in the car we can not pay attention to firewood, rice, oil, salt, sauce and vinegar tea
So I would like to say: thank you S7 for your company all the time! Because of S7, I will unconsciously like her, take care of her and develop another hobby, or it is also a preference, time flies-choose a car, buy a car, use a car, to love a car! S7 smooth road black third maintenance Syria! The same sentence came to [Ika] to let us record life like a movie.

Combined with the use of my magic speed S7, slowly Xiaoqi has driven 21380 kilometers. I remember that the mileage of the second maintenance was 12123 kilometers, and we took the time to do the third maintenance of S7 seriously. I believe many riders know that maintenance is all about changing oil. But there are really some riders who don’t know what brand of oil to change. Because from time to time, some car friends will ask this kind of question in the Q group of the car club and in the question cards on the forum.
In June this year, I heard that there were car friends who went to do maintenance. I handed in the maintenance manual car and sat directly into the customer lounge. I picked up the car two hours later and asked him what the maintenance had done. He directly six words “do not know did not pay attention” probably in the customer lounge to play 98K Battle Royale Games fascinated!
It is suggested that motorists should be on-site attendants when sending cars for maintenance, and we can learn a lot through the maintenance process. I just don’t know what to ask, so every time I maintain myself, I will watch and learn the whole maintenance process on the spot.

▲ maintenance– it is said that the engine oil is changed, but there is actually a lot of knowledge in it.
During the use of our vehicle engine, mechanical impurities such as dust, metal debris and carbon deposits will continue to be mixed into the oil. At the same time, the oxidation effect of air and combustion exhaust on the oil will also make the oil gradually produce colloid. The mixture of mechanical impurities and colloid will also form sludge, which will not only accelerate the wear of engine parts, but also easily cause oil road blockage. In order to ensure the cleanliness of the oil, an oil filter is installed in the lubrication system of the engine. It is generally recommended to replace 12000 km of oil at 7500 Murray, but it can also be decided according to the actual situation. It should also be noted that the old oil contains more impurities than the newly replaced oil, and the service life of the oil filter will be shortened. So every maintenance I plan to do at 10000 kilometers, change the engine oil at the same time replace the new oil filter.

▲ for turbocharged cars should be different from naturally aspirated cars in maintenance. After studying and summarizing in various forums and XBB, this is the way to maintain her car.
We all know that oil (lubricating oil) can help engine lubrication and wear reduction, auxiliary cooling and cooling, sealing and leakage prevention, rust and corrosion prevention, shock cushioning, pressure transmission, cleaning and so on. Today’s turbocharged engine technology has made greater progress, is no longer as delicate as it used to be, and is not much different from natural suction in routine maintenance. So often clean the filter, we need to regularly replace and clean the engine oil, filter, air filter and so on to reduce impurities, which can effectively prevent excessive wear and tear of the turbine engine blades. therefore, when our car arrives at a given time or kilometer, the oil filter and air filter as well as the engine oil should be replaced in time, so that the car can maintain good working conditions. Thus prolonging the service life of the car.
As for the turbocharged engine, if it is filled with inferior oil, it will cause the floating turbine spindle to lack of lubrication and heat dissipation function, thus damaging the oil seal and causing oil leakage, so it is recommended that motorists use better oil when maintaining. The engine oil can not only lubricate the engine, but the turbocharger also needs lubrication and cooling. It is recommended to use fully synthetic and semi-synthetic high quality oil, which has better oxidation resistance, wear resistance, high temperature resistance and heat dissipation. It is of great benefit to the maintenance of the turbine and the working conditions of the whole engine. The picture above shows “Kunlun Tianrun” fully synthetic 5W-40 engine oil, which I have been using all the time. Help engine lubrication and wear reduction, auxiliary cooling and cooling, sealing and leakage prevention, rust and corrosion prevention, shock cushioning, pressure transmission, cleaning and other functions.

▲│ mineral engine oil: based on mineral oil with a small amount of additives. It can basically meet the daily driving requirements, and the price is cheap, but the cleaning and repair ability is relatively poor, and the life of the oil is relatively short.
▲│ semi-synthetic oil: strictly speaking, it also belongs to mineral oil, adding a large number of additives, lubrication, cleaning, repair capacity has been improved, life has also been extended, the price is not very high, semi-synthetic oil is suitable for economical riders.
▲ 丨 Fully synthetic engine oil: Engine oil that is artificially synthesized using chemical methods. Formulations of different substances will be used depending on the purpose of use. It has a good performance in terms of lubricity, cleanliness, and repairability. Cold start is also better, and its oil change cycle is longer. After comparing the three types of engine oils, fully synthetic engine oil is more expensive in price.

▲ New air filter
There is a lot of dust suspended in the air, the main component being silicon dioxide. This is a substance that is harder than metal. Installing an air filter in the engine’s intake control device can reduce the wear caused by these substances on parts such as cylinders, pistons and piston rings. If the car does not install an air filter, cylinder wear will increase by 7 times, piston wear will increase by 3 times, and piston ring wear will increase by 8 times. Therefore, an air filter must be installed in the engine’s air intake control device.
We clean the air filter every time we change the oil. When cleaning, take out the filter element and gently pat it on the end face, and blow it with compressed air from the inside out to remove the dust on the core. Do not wash it with gasoline or water. Generally, every 2 to 3 oil changes, the air filter must be replaced with a new one.
