It’s a pity that the 22-model standard shaft is second guaranteed. The spark plug of the fourth cylinder is a little oily

August 15, 2024

I have 22 standard axle 530 fashion models. When the first maintenance period was 10,000 kilometers, all four spark plugs were empty of oil. Today, I checked it again for the second maintenance period of 20,000 kilometers. Unfortunately, there is a little oil in the fourth cylinder, but fortunately it is not much. The front position of the BMW 4-cylinder b48 engine is cylinder 1, and then it is sorted in turn. The steering wheel position is cylinder 4. I think the overall condition of the spark plug is okay, but I haven’t replaced it. I will replace it according to the situation when the next 30,000 kilometers. Other air filters, air conditioning filters, and gasoline filters have not been replaced. They are very clean and there is no need to replace them. I checked the oil dipstick again before maintenance today and found that the amount of oil had not decreased. The first guarantee was 5.25 liters of oil. This time, 5.25 oil is still added for the second insurance, which is enough. There is no need to add 5.75. You can tell the store in advance how much oil to add during maintenance. In fact, I personally think it is actually possible to add 5 liters. For everyone to use standard axle drivers as a reference. If some accessories do not need to be replaced, you can still decide whether to replace them based on actual use, and don’t listen to all 4s instructions. However, I personally suggest that accessories for related parts of the engine should be replaced as much as possible in 4s, and other insignificant external components such as filter elements. There is no problem with replacing them.
