The status of the spark plug inspected today shows that the current total mileage is 32000 kilometers. For the fourth maintenance, this set has run for 15000 kilometers. It is in good condition, there are still oil stains, and the carbon deposits are significantly less than last time.

This picture shows the spark plug that was removed during the 18000-kilometer second guarantee. It is in very bad condition.

Ask two questions:
1. Do you have any drivers who feel that after filling up a tank of oil, the driving power of the car in the front half of the tank and the back half of the tank is different? The throttle in the first half of the tank is very light. If you step on the throttle lightly, the car will respond quickly and the acceleration and drag feel will be very light; after half of the tank, the throttle becomes fleshy, the feet feel will be heavy, and the acceleration delay and drag feel will increase? Once, the fuel tank reached a bottom halfway and 50 yuan of oil was added. After leaving the gas station, it immediately felt like it had changed.
2. Turn on the air conditioner. After the compressor is started, the steering wheel can be obviously shaken, and the car can also be shaken on the central armrest. It is obvious when parking in place; it will be much better if the air conditioner is turned off or put in neutral.
