Status report on the 2022 modified second long axis 5 series 5700-kilometer spark plug

  30
 August 1, 2024
The engines are B48TU, B48B20D
Valve cover number 102086802
The number of kilometers is 5700KM, the overall fuel consumption is 8.9, the high speed accounts for 30%, and the city and town roads account for 70%. Since today, almost all new cars have been run with ECO PRO for the first time (at that time, some fans said that when using the energy-saving mode, carbon deposition or engine oil leakage would be more obvious, so they deliberately tried it like a guinea mouse).
Today’s first guarantee, the following is the status of spark plugs in cylinder one and three.

Each cylinder of spark plugs is black, but it doesn’t have oil. It’s still dry, right?

A three-cylinder spark plug is drier than a one-cylinder spark plug.

What will happen if there are more kilometers in the future? Let’s see later.
By the way, the oil was still full before the first insurance, so I forgot to take a photo.
An audience friend with the same engine valve cover left a comment that this car is not driven much.
