Fourth maintenance record of standard shaft 5 series

July 31, 2024

During the third guarantee, the 1122 vehicle engine system was upgraded, the spark plug was replaced, and the 0W-20 engine oil was upgraded for free from the 5W-30 engine oil of the first guarantee and the second guarantee. The first two maintenance operations were 5.25 liters. Put it out for measurement every time for maintenance, and about 4.3 liters are left. It’s like consuming one liter of oil for 10,000 kilometers. Today, Saturday, I took my son and set off to the 4S shop early in the morning.

It’s almost 7,000 kilometers after the third guarantee, and the oil level is still normal.

Last time, I consumed one square for four to five thousand kilometers, which is very rare!

About 7,000, it dropped by one square

It dropped by two squares when it was more than 9,000 kilometers.

After arriving at the 4s store, my son found an empty desk and started his homework

Start draining oil, and the engine oil is not black for 10,000 kilometers.

It will have to be replaced sooner or later. The domestic M5 aluminum alloy rear trailing arm is on the market.

More oil than last time.

I added 5.25 liters last time, and released 4.5 liters! 4.3 liters were released during the third guarantee period. Consumption is 0.2 liters less than before.

4.5 Raise used oil. Reason for low consumption: Because of the upgrade of 1122, the oil temperature has dropped? Or is it less resistant to upgrading from 5W-30 oil to 0W-20 oil?

The throttle cleaning was given for free anyway. When I opened it and saw that it was clean, the mechanic said that your car was still so clean after 40,000 yuan. Open the throttle, wipe it with a cloth and install it. There is no so-called motor oil

Add 5.25 liters of oil. The remaining half liter will be taken away in the trunk. Two liters of oil were left after four maintenance attempts.

0-20

add oil

The difference from the domestic production is that the imported version of the B48TU fourth cylinder spark plug contains oil. I asked him to remove the spark plug of the fourth cylinder directly. There is still oil.
