21 model 530li four-wheel drive sports, replace the spark plug.

July 31, 2024

The normal maintenance manual for spark plugs will be replaced at 20,000 kilometers. Looking at the forum, everyone will be replaced at 30,000 or 40,000 meters. Today, it was exactly 30,000 kilometers of maintenance, so it was replaced directly. The riders helped to check if the spark plug that had been replaced had penetrated, but they didn’t quite understand it. hahahaha

There is also an upgraded 0W-20 engine oil, with 5.25 liters added,
Add 5.25 liters to the emphasis on maintenance
