Did the 21 model 530 four-wheel drive burn oil?
MabelRobbins 
12 When the first insurance was in July, there was oil on the spark plugs of cylinders 1 and 2, which was also darker than the ones of cylinders 3 and 4. The endoscope found serious carbon deposits and oil stains in cylinders 1 and 2. The 4S shop gave feedback to the manufacturer, and replied that it was normal. Is it normal to have oil in the cylinder? Are there any riders who have successfully claimed? Should I cover the ventilation door? 5.75L of engine oil was added to the first insurance
