Is Engine Oil Additive Harmful to Cars?

Do You Need to Turn on AC for Car Heater?

You do not need to turn on AC for car heater. The AC in a car is the switch for air conditioning cooling, while the car heater mainly utilizes the heat circulation principle of the coolant to generate warmth. The method to switch between cooling and heating in a car air conditioner is as follows: 1. Generally, the car air conditioner switch is a rotary knob divided into two ends—one end is for cooling (blue), and the other end is for heating (red), each marked with different intensity levels to adjust the cooling or heating strength. 2. If you need cooling in summer, rotate the air conditioner switch to the blue end and turn on the AC switch to activate the compressor for cooling. 3. If you need heating in winter, rotate the switch to the red end without turning on the AC switch. When the air conditioner is not in use, simply rotate it to the off position. 4. Whether you are using cooling or heating, adjust the intensity level according to your comfort. If you feel cold, increase the heating level accordingly.

Should the Rear Crankshaft Oil Seal Leakage Be Repaired?

If the rear crankshaft oil seal leakage is not too severe, replacement is unnecessary; however, if the leakage is particularly noticeable, it should be replaced. The main causes of rear crankshaft oil seal leakage include the following aspects: 1. Natural aging of automotive parts. When a car has been driven for too many years, the rear crankshaft oil seal may age, causing cracks at the lip and resulting in oil leakage. 2. Incompatible lubricant. If a non-petroleum-based lubricant is not used during the production of the rear crankshaft oil seal, it may lead to loosening and detachment of the seal, ultimately causing oil leakage. 3. Non-parallel pressing and installation surfaces of the rear oil seal. If the pressing and installation surfaces of the rear oil seal are not parallel, uneven force distribution on the lip may occur, leading to deformation during long-term compression and resulting in oil leakage. Note: The oil seal is used to seal lubricating oil, isolating lubricated components from various oils to prevent leakage.

Which model is the Corolla d4t?

Corolla d4t refers to the 2021 Corolla 1.2T model. Meaning of D4T: D-4T indicates that this Corolla is equipped with a 1.2T four-cylinder direct injection turbocharged engine. D4 refers to the inline 4-cylinder engine, and T stands for turbocharging. Turbocharged engine: A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It utilizes the inertial force of the exhaust gas from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller pressurizes the air delivered from the air filter pipeline, forcing it into the cylinders. As the engine speed increases, the exhaust gas discharge speed and turbine speed also increase simultaneously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel.

What is the ground clearance of the Ford EVOS?

The ground clearance of the Ford EVOS is 190mm. Characteristics of high ground clearance: Commonly seen SUVs and off-road vehicles have higher ground clearance, which provides strong off-road capability and reduces concerns about scraping the undercarriage. However, higher ground clearance also results in poorer vibration damping, making the ride comfort inferior to that of sedans. Additionally, due to the higher ground clearance, the center of gravity is also higher, leading to relatively poorer body stability, especially when cornering, where body roll is more pronounced. Therefore, the speed limit for such vehicles should be lower. Characteristics of low ground clearance: Lower ground clearance reduces the center of gravity, improving tire grip, which greatly benefits vehicle acceleration and performance. Additionally, lower ground clearance reduces air resistance and minimizes power loss, allowing the car's performance to be fully utilized. This is why performance cars typically have very low ground clearance. However, low ground clearance results in poorer road adaptability, requiring the vehicle to operate on very smooth roads.

How Long is the Validity Period of a Long-Term Driver's License?

The validity period of a motor vehicle driver's license is divided into 6 years, 10 years, and permanent. During the 6-year validity period of the driver's license, if the driver has not accumulated 12 penalty points in each scoring cycle, they can exchange it for a 10-year validity license. If they have accumulated 12 points, the license will remain valid for 6 years. During the 10-year validity period, if the driver has not accumulated 12 penalty points in each scoring cycle, they can exchange it for a permanent validity license. Below is additional information: Article 57 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses' stipulates: A motor vehicle driver shall apply for a license renewal at the vehicle management office of the issuing authority or another location 90 days before the expiration of the current driver's license. When applying, the driver must fill out an application form and submit the following documents: 1. The driver's identity proof; 2. The current driver's license; 3. A medical certificate issued by a county-level or higher medical institution or a military medical institution at the regimental level or above. For applicants applying for a special small automatic passenger vehicle for the disabled, a medical certificate issued by a specialized medical institution designated by the provincial health authority must be submitted.

Should You Use Internal or External Air Circulation When Parking?

When parking, you should turn on the external air circulation. If you plan to rest in the car with the air conditioning on, make sure to periodically switch to external air circulation. Using internal circulation continuously can lead to carbon dioxide poisoning. Below are some tips for using the car's air conditioning: 1. After the car has been exposed to the sun outdoors, first turn on the external circulation to ventilate and dissipate heat. You can also open the windows and sunroof to speed up the cooling process. After 3-5 minutes, when the interior temperature has stabilized, close the windows, turn on the cooling, and switch the air conditioning to internal circulation. 2. In cold weather, wait a moment after getting in the car until the engine temperature reaches the normal level. Then, turning on the heater with internal circulation can quickly raise the temperature. 3. During traffic jams, it's best to turn off the external circulation to block exhaust fumes from the vehicle in front. 4. When driving at high speeds, you can turn on the external circulation as needed. Since long drives at high speeds can make the air inside the car stale due to prolonged internal circulation, using external circulation helps maintain a comfortable temperature while providing fresh air.
