I haven’t been to the forum for too long.

Taking advantage of the recommendation of all the leaders in the forum, I bought Anso’s blue cover gearbox oil and Mott’s differential oil, and I tried it in advance for 146000 kilometers. There were many of the same homework, so I handed in a simple assignment, except for the oil. The rest of the accessories were taken from the store, and the working hours were added, which cost a total of 950. unexpectedly, changing a low-viscosity oil solved the problem of frustration in my car.

After driving for a while, by the way, I wrote the feeling together, and I stopped talking about the differential oil. I mainly talked about the feeling of the gearbox oil:
1. Rush to change the gearbox oil in more than 40, 000 kilometers, because stepping on the throttle 1 and 2 gears at about 1500 rpm will cause occasional setbacks, and even on the road after a hot car in winter, the frequency of the hot weather is much less, and the gearbox oil will no longer appear when it reaches the working temperature. observe the data through the box, such as the torque converter in the process of opening to the lock, after the change of Anso oil, this occasional setback at 1500 rpm has been completely absent these days. The frustration of the small throttle and the low gear of the traffic jam in the past is gone.
two。 In the past, when you hit the brakes and cut N gears in D or R gear, the car body will wobble a little, but after changing oil, this jitter will be obviously reduced.
Last time, it cost more than 3200 to change the gearbox oil in 4S when it was 100000 kilometers. I came back and found that it had been changed. I didn’t know that there was no oil in the torque changer, so I ran 46000 kilometers and changed the oil in advance, and the oil was very clean. It’s obviously different from the oil change before.
This time, the oil pan is very clean. I pulled it with a screwdriver. There is no deposit at the bottom of the shell, but there is a little iron filings on the magnet. What is whitening on the right is because of the light. In fact, there is no oil mud. It is very intuitive to look at the dark part on the left. The first two oil changes, the same 4S change, the oil pan has oil sludge. I don’t know if the gearbox oil brand has been changed or the vehicle has entered a stable period of running-in. It feels easy to change oil when driving up to 60,000 kilometers.
This time, I watched the master open the torque converter cleanly. This small screw is not in stock and will continue to be used for the previous tightening, but the copper gasket on the screw is already very thin. It is best to use it twice or replace a new gasket. So far, no oil leakage has been found.
Pay special attention to the fact that the new filter element is this triple fine filter element, the one with angles around it.
The sealing gasket of the original factory has such lines on it. If you touch it with a sense of concavity and convexity, you must be careful not to use it from the deputy factory. It will be troublesome to change it if you miss it.
The original oil is turquoise, while Anso’s oil is red. This bottle is about 9.4 liters, using a little washing and filling pot. Finally, there is a little bit left in the pot, which should be added to close to 9 liters.
The differential oil is also changed at 100000 kilometers. With the strict version of the recommended Anso, the color released feels the same as the new oil, unlike the original oil, which is milky white, so if you open it gently, even if it is an Anso oil, it is no problem to change it.
This needs to be said separately, if you want to wash the differential first, it is better to add a little less, or add more, not all, because this bottle is not like Anso’s differential oil is soft packaging, it is easy to add, directly into the differential, some of the oil in this bottle is not easy to pour out, it doesn’t matter if there are other auxiliary filling devices.
On a separate line, please take a look at the leakage of the turbine intake pipe, mainly the strict version, the he version and the brothers and sisters. This maintenance, when the front guard of the engine was removed, it was found that there seemed to be oil leakage from the pipe connected to the turbine intake.
After thinking about the leakage from the black pipe above, it should be that the walnut sand was washed and deposited carbon before. To disassemble this pipe, the pipe was very tight. Later, it was heated and disassembled with a hot air gun. I don’t know if it was not installed in place to cause oil leakage.
100000 kilometers to now, there is no dripping, just a layer of mud, the car drives normally, the power is also very good, 10,000 kilometers to change oil, there is no lack of oil, so I would like to ask what is the cause, does it need to be dealt with? Thank you.
