Wo’s first maintenance

As the saying goes, if the horse wants to run, the horse wants to eat grass, we strongly despise friends who want the horse to run but refuse to give the horse grass!!! Unconsciously, it had been a year since the car was picked up, and the 5-kilometer odometer had reached the number of 9886. Maintenance services were booked in advance to allow the car to return to the factory for a comprehensive physical examination and maintenance.

This is the first time I see such a large bucket of engine oil. There is one point that everyone should pay attention to. There is no difference in appearance between 0-20 and 5-30 oils on the market. The official data is: all oils use 5W/30 oil (recommended retail price including tax: 95 RMB/liter) as the basis for calculating the recommended retail price of the package. If you need to use 0W/20 engine oil (recommended retail price including tax: 133 yuan/liter) or 0W/30 engine oil (recommended retail price including tax: 133 yuan/liter), the recommended retail price of the above package will change accordingly. Please refer to the actual settlement price of Volvo meized dealers. My understanding is that due to the oil film, the 0W-20 will save fuel more than the 5W-30, and the engine sound will be quieter. Decisively go 0-20!
After changing the oil, I tidy up and upgrade the new system, upgraded to 2.0, and connected the external power supply. The overall upgrade process takes about 1 hour. The avoidance function for passing cars has been added. I like Volvo! After the upgrade, I feel that the gearbox has improved steadily. The engine idle speed has dropped by 50 revolutions and now it is 800 revolutions. The shift sound is more harmonious. The automatic braking function icon has changed. Other functions are still under study, and there is an opportunity to specifically explain them at the beginning.
I wish everyone in advance a happy 38th Festival and a happy family!
