Maintain the 21 BMW 530 model to see if it burns oil
ClevelandNoyes 
6 Unconsciously, my 21 model 530 ran away. The first insurance for 20,000 kilometers was more than 8000 yuan. I started working on the second insurance today. I shared the details with you and let you see if there was any burning oil. I think it may be a slight amount of burning oil during the first insurance. The engine oil added 5.75 liters to the first insurance and ran 12,000 kilometers. The display was still the highest, but the spark plugs on the first and second bars had some carbon deposits and oil, but it didn’t feel very serious. I sent the picture to everyone to see if it was a little burning oil. Moreover, I asked the 4S store and said that there were new valve covers to check and apply for replacement when applying for three guarantees.

The original spark plug is the champion, and the younger brother told me that the new 530 must be replaced by 20,000 kilometers, because the engine temperature and oil pressure are high, but it can only run 30,000 kilometers at most.
This is the removed spark plug of cylinder 1234. There are oil stains in the first and second cylinders, but the carbon deposition is not very serious.
Everyone zoom in on the picture and watch it
Because the air conditioning compartment and air compartment had been replaced by themselves, the oil and spark plug were simply changed and the project was completed.
The 5.75 liters of oil I saved before was still at the maximum position after running 12,000 kilometers
