Xiao Xin’s pre-holiday maintenance

As there was always something wrong with my car some time ago, and it happened that the mileage had arrived, I planned to give it a thorough maintenance and take good care of it before the Spring Festival. This time, there are many original accessories, including original black drill full synthetic oil, original oil filter element, original gasoline filter element, oil discharge screw, and two bottles of glass water. The most important one is the total synthetic oil, so why choose the black drill full synthetic oil? As we all know, the base oil of mineral oil is the poor composition of crude oil after fractionation of useful light substances (such as aviation oil, gasoline, etc.). Total synthetic oil is propylene dispersed from gas or natural gas in crude oil, and then refined into a lubricating fluid composed of macromolecules by polymerization, catalysis and other complex chemical reactions, using better components in crude oil. after chemical reaction and artificial control to achieve the expected molecular form, the molecules of the total synthetic oil are neatly arranged and have a strong ability to resist external variables. Compared with the two kinds of oil, the total synthetic oil has a good foundation, and the ability of thermal stability, anti-oxidation and anti-viscosity change is much better than that of mineral oil. Putting aside these complicated things, in a word, all-synthetic engine oil is good. How to choose the viscosity and grade of the oil? In fact, instead of hearsay, it is better to open your car owner’s manual, it is written clearly, what kind of viscosity is good, what kind of grade, there are all above. Whether the oil is good or not, whether it is right or not, there will be a feeling as soon as the car is driven after it is added. In addition, we must buy oil through regular channels and beware of inferior products and fake oil.
I. introduction of car owners
Ika ID: meteor shower
City: Dalian
Car series: 2013 Xin Rui
Mileage: 12w km
Maintenance content: change oil, oil filter element, gasoline filter element
II. Replacement process
Love the car to the store, the little brother in charge of the reception is seriously helping me to register and estimate the cost.
The car entered the station smoothly and the maintenance was ready.
These are all the original accessories today: there are 4 L black drill synthetic oil, 1 original oil filter element, 1 original gasoline filter element, 1 oil discharge screw, and two bottles of glass water.
Make a close-up of the original black drill oil, which is especially suitable for winter, especially in Northeast China, which not only has excellent cleaning performance, but also has suitable viscosity, good lubrication effect and easier start-up at low temperature.
Take a look at the reverse side and the side, there is a ruler on the side, each bottle 1L, a total of 4 L, every 10,000 km need to be replaced.
This is the oil filter element of the original factory.
There is also the original gasoline filter element, which needs to be replaced every 30-40,000 kilometers.
This is an oil drain screw. I change the oil every time I change it.
There are also two bottles of glass water from the original factory, which are saved in the trunk for long-distance running.
Take a picture of these guys.
If the friends are going to switch to full synthetic oil, it is best to first clean the oil path of the engine lubrication system and clean up some of the deposits in it, so that the newly replaced oil will work more effectively. Master is helping me clean the lubrication system.
The next step is to lift the car high and clean the old oil.
You can see that the old oil is very black after cleaning the oil circuit. Here is an explanation: there are two reasons for the blackening of the oil: too much carbon accumulates in the ① engine; the old oil is not cleaned when ② changes the oil. Therefore, cleaning is very necessary.
At my request, continue to suck up the old oil with a straw.
Then remove the old oil filter element and replace it with a new one.
The old oil filter is covered with dust.
The next step is to pour in the black drill oil. The golden color is really beautiful.
And replace the gasoline filter.
Wash the car after maintenance.
The total cost this time is 758 yuan, including all accessories and man-hours.
III. Summary
After maintenance, I feel that the throttle pedal has become more sensitive, the engine sound is much lower, the gear up is smoother and faster, and the most important thing is that the fuel consumption has dropped from 10 oil for 100 kilometers to 6.3 oil for 100 kilometers. I have to say that the quality of black drill is good, and meticulous maintenance has been rewarded.
