BMW 525Li first guarantee

8 The car is a 525LI. It was brought up on May 10 last year. It has already traveled 10,000 kilometers. I made an appointment for maintenance today. There were a lot of vehicles under 4S maintenance before the Spring Festival. It took almost an hour and a half before the vehicles entered the repair workshop. Since I have replacements, minor maintenance is free for 5 years. I learned a lot about engine oil in the forum before, and the original 5W-30 fully meets the demand. However, many motorists recommended the 02W-20 machine, so they made up for the difference of 180 yuan and upgraded to this engine oil.
In addition, I specifically instructed the maintenance personnel to only add 5.25L and take away the remaining half bottle. As a result, the 4S people asked me to sign the work order, saying that I would bear the risks brought by it, and reluctantly signed it.
I don’t know how many liters of oil were added when leaving the factory. Anyway, after adding 5.25L, I felt that the engine was louder than before maintenance and it drove smoothly. Maybe it was a psychological effect. I’ll still use this engine for five years, and after five years, I’ll use 5W-30 engine oil with high viscosity. Anyway, it’s free. By the way, I forgot to mention that I received free minor maintenance from the manufacturer for 5 years, and after 5 years, the seller gave free minor maintenance for life.

This is the oil I use. The maintenance staff said it is better than the 5W-30 oil. I believe it, the price is almost 87 yuan/L more expensive.
