Using low-quality engine oil during car maintenance may lead to decreased power, increased fuel consumption, and damage to the catalytic converter, among other consequences. Here are the benefits of using high-quality engine oil: 1. Fuel efficiency. High-quality engine oil has excellent lubrication and cleaning properties, ensuring smooth and normal engine operation. Compared to most engine oils, high-quality oil is more fuel-efficient. 2. Better shock absorption. Lubricating oil has shock-absorbing effects, and high-quality engine oil can also reduce noise and minimize engine wear. 3. Energy-saving and eco-friendly. Nowadays, energy conservation and carbon reduction are widely advocated. High-quality engine oil offers superior sealing performance compared to most engine oils, effectively preventing oil burning issues. In the long run, it not only saves money for car owners but also contributes to energy conservation and environmental protection.

Should the Nail Puncturing the Tire Be Removed?

Tire punctured by a nail but not leaking air is not recommended to pull out. Because if the nail has already pierced the tire, pulling it out will cause severe air leakage, making the vehicle unable to continue driving; moreover, if the tire pressure is high, removing the nail might even lead to a tire blowout. The correct approach is as follows: 1. If driving normally, proceed at low speed to the nearest repair shop, then remove the nail and check whether the tire is punctured and leaking air. 2. If there is air leakage, you can directly proceed with repair or replacement, which is safer. Note: Many cars now use vacuum tires. If the tire is punctured by a nail, the air leakage will be very slow, providing sufficient time to drive the vehicle to the repair shop for inspection.

Why are there two levers under the left side of the MG ZS steering wheel?

The two levers under the left side of the MG ZS steering wheel are divided into upper and lower positions. The upper one controls the turn signals, while the shorter lower one is the cruise control lever. Cruise control is a highly useful feature for improving driving comfort, especially on highways or in urban road conditions with minimal traffic and few red lights. Cruise control's overtaking and resume functions: 1. Overtaking function: Some vehicles allow acceleration by pressing the throttle even while cruise control is active, which can be used for overtaking. After releasing the throttle, the speed automatically returns to the originally set cruise speed. 2. Temporary cancellation: Lightly tapping the brake temporarily cancels cruise control. Without pressing the throttle, the vehicle will gradually decelerate. 3. Resume function: After temporary cancellation, the vehicle often slows down. Pressing the resume button automatically restores the original cruise speed, giving the sensation of the vehicle accelerating on its own.

What does a license plate starting with 'hn' mean?

A license plate starting with 'hn' belongs to the General Armament Department. Civilian license plates do not have categories that start with letters; all civilian license plates begin with Chinese characters. The Chinese character on a civilian license plate represents the province or municipality directly under the central government, and the letter following the first character represents the city or district. A license plate, commonly known as a vehicle plate, is a panel hung on the front and rear of a vehicle, usually made of aluminum, sheet metal, plastic, or paper, inscribed with the vehicle's registration number, registration region, or other relevant information. License plates serve as a numbering and information registration system for vehicles, with the primary purpose of identifying the vehicle's region of registration and enabling the tracking of the vehicle's owner and registration details based on the plate number.

What is the reason for the yellow engine light in the Cruze?

The reason for the yellow engine light in the Cruze is poor fuel quality. By draining all the poor-quality fuel and refilling with high-quality fuel, the engine fault light will automatically turn off after running the engine for about 30 seconds. Fuel quality is the primary factor causing the engine fault light to illuminate. The anti-knock property of gasoline is indicated by the octane number—the higher the octane number, the better the anti-knock performance. Taking the Cruze 2018 Hatchback 320 Automatic Pioneer Sunroof Edition as an example: the manufacturer of this car is SAIC-GM Chevrolet, classified as a compact car, with an energy type of gasoline, a 6-speed automatic transmission, and a body type of 5-door, 5-seat hatchback.
