[Jinjixing Engine Oil Trial] Replacement of Jinjixing 5w30 Engine Oil

September 23, 2024

Hongtang Town Building

First of all, I would like to thank Aika and Great Wall Lubricants for providing this opportunity and bringing tangible benefits to our Aika cyclists.
Tell me about the car. Originally intended to use the old Lechi for this test, but Lechi now belongs to the brand protection vehicle, and hardly uses it. After consulting the recommended model advice of the manufacturer’s 4s store, it is decided to use the current main car. BYD Tang 2018 pioneering model for this trial evaluation. (the factory manual is recommended as 5w40, the coordinates are northwest, and the factory says there is no problem with 5w30.) The car was purchased in mid-November 2018 and currently has a total mileage of 10438 km, of which the hybrid mileage (that is, the mileage using the engine) is 6142 km, almost all of which are highways and national highways. This maintenance is the second guarantee, the first guarantee is in May 2019, the total mileage 60xx, mixed mileage 34xx, the use of all oil products donated by the original factory. This evaluation is also thanks to the strong support of the local ssss, allowing me to bring my own oil (but for well-known reasons, I was unable to take pictures when adding Jinxing. ).

Outer case on arrival

The internal packing is very good, with an air column bag.

The oil is in good condition and does not leak.

The protagonist Jin Jixing J700 5w30 has one big and one small two buckets.

The staff of Aika really didn’t say that they received the express message on the logistics app that night after confirming the receiving information with me. Two days later, the outer box was in good condition, and the oil products were packed in the gas column bag without leakage.
Besides, the appearance of oil products, simplicity and novelty is my first impression. The vat is different from the general oil, the filling port has a square protective cover, personal praise for this design, compared with the traditional oil barrel, this design is not easy to damage, and easy to store. The material of the oil barrel is smooth and even, and the touch is solid, so the products produced by the big factory are sure enough.

It has been suggested for maintenance. I’m really lucky. Thanks again to Aika and Great Wall Lubricants.

Run to ssss

Tell me about Don’s cabin.

It’s all surrounded out like this.

After opening it, you can see the air filter box, the engine cabin is under the air filter box, if you replace it yourself, it is more complicated, and there is no mechanical oil dipstick.

Waiting for the car to be delivered

Enter the station and get ready to hold it high.

You have to wear a helmet before you can enter the workshop. In fact, it is forbidden to enter the workshop during special periods, but fortunately, you have a good relationship with the store.

It is difficult to lift a 2.5t car.

Motor position

The original oil released, it’s so dark.

In the middle, it is forbidden to take pictures. Here, I will tell you in words. After Jinjixing engine oil was opened, I took a special look at it. The oil color was clear and the transparency was very good. During the filling process, I specially asked the master to pull up the cylinder body to have a look, the fluidity was very good, and the gravity filling flow was very linear, thin and slippery. The master said that the oil was very good and felt no lower than the extreme protection in the 1xxx package in the store.

The maintenance was completed and the after-sales manager handed over the car in person. I was flattered.

Current mileage 10438

Immediately after the maintenance is completed, go to the highway, mountain road and unpaved road for testing. Simply tell me how you feel. First of all, the noise is much better than the free oil guaranteed by the first guarantee, especially on the highway, the roar of the engine is more supple, there is no instant noise before overtaking at 2200 revolutions, and the 1400 revolutions are driving normally. The highway and the national highway have been masked by the wind noise. There is no loud sound. At the idle speed of 700 rpm, the sound of engine start can be heard obviously, which is less than the original free engine oil.
In terms of power, because there is no habit of intense driving, power is as good as ever, and power is on call on unpaved roads and uphill mountain roads.
With regard to jitter, I felt a slight wobble during idling. I consulted the store, which should be caused by the long storage of gasoline in my tank (I filled up before the Chinese New year in January, and there is still 1max 3 at present). After that, I will bring you a follow-up after the replacement of gasoline.
