The old 5 series was maintained for 40,000 kilometers and replaced with spark plugs and oil filters

The 19 model was modified 530li Zunhao, which cost 38,000 yuan. Recently, he received maintenance tips, so he visited the 4s store on the weekend (bought a one-year extended warranty).
The after-sales buddies were very enthusiastic and proactive, saying that in recent store activities, replacing the spark plug and the oil filter together cost only more than 100 yuan more than replacing the spark plug alone. Change directly after thinking about it!
Then when I saw that my extended warranty expired in May, I volunteered to check if there were any other mechanical problems and could be replaced through warranty.
After a comprehensive inspection, it was found that they were all minor problems such as aging cracks in rubber parts. I only applied for replacing the steering rod rubber sleeve, steering wheel steering shaft, and left rear horn horns.
The oil was added to the work order by 5.3 liters (engine model b4820d). Although it had always been added to 4.8 liters before, after the official increase to 5.75 liters, this was considered merciful…

The spark plug looked okay after it was removed. It was originally planned to replace it after 4w, but now it is not much worse, so I just replaced it.

Finally, I used a basic maintenance voucher (oil filter) that was given when I bought a car, which cost 2k +

The old spark plug looks okay, but it’s hard to see if there are oil stains at the threaded opening

Why does this oil amount look like 5.75 liters?
