Can Semi-Synthetic Engine Oil Be Changed Once a Year?

Semi-synthetic engine oil should not be changed only once a year; it is recommended to replace it every 7 to 8 months. Otherwise, it may deteriorate easily, leading to increased carbon deposits and, in severe cases, oil burning issues. The replacement cycle for semi-synthetic oil is approximately 7,500 kilometers, so it's advisable to change it on time. Different brands of engine oil have varying formulations, resulting in differences in viscosity, anti-wear properties, corrosion resistance, anti-knock performance, and volatility. Mixing different brands may cause incompatibility or reactions, so oils of different brands should not be mixed. Semi-synthetic oil is one type of automotive engine oil, made using semi-synthetic base oil.

How to Apply for Special Vehicle Registration for Pickup Trucks?

Pickup trucks can only apply for special vehicle registration through agency companies. Below is relevant information about special vehicles: 1. Overview: The full name of a special vehicle is 'Light Non-Cargo Special Operation Vehicle.' This type of vehicle inherently falls under the category of trucks. However, because it is classified as a 'special vehicle,' it is allowed to operate within urban areas. 2. Advantages: With this registration, the vehicle gains the same road rights as passenger cars, thereby avoiding urban traffic restrictions and highway speed limits, offering high cost-effectiveness. 3. Notes: Policies vary by region. For example, in Beijing, only special operation vehicles with designated body colors and national markings are permitted to enter urban areas. Personally purchased special vehicles are managed as regular pickup trucks.

Do Spark Plugs Affect Engine Power?

Spark plugs affect engine power and fuel consumption. The strength of the spark and the timing of ignition directly determine the combustion results. High-quality spark plugs provide stable performance at both high and low speeds, produce strong electric sparks, and ensure complete combustion of the air-fuel mixture, resulting in stronger power output and better fuel efficiency. The electrodes of the spark plug continuously generate sparks to ignite the air-fuel mixture in the cylinder. Other components of the ignition system produce precisely timed high-voltage electrical pulses, creating sparks and explosions that provide the energy required for engine power output. Spark plugs are devices that ignite the air-fuel mixture entering the engine combustion chamber, operating under extreme conditions of high temperature and high pressure, making them one of the wear-prone components in gasoline engines.

How to Drain Oil from a Car?

Methods for draining oil from a car: 1. Draining oil on a flat road is not easy. To drain oil from a small car, first fill the fuel tank, then drive to a slope, put the gear in first, pull the handbrake, and secure the car properly; 2. Open the fuel tank cap, insert a pre-prepared soft tube into the tank as far down as possible, use airflow to draw the oil out, and prepare a container for the oil. This is a traditional method for draining gasoline from a car, but it cannot completely drain all the gasoline. When oil needs to be drained, you can go to a repair shop or a 4S store to use professional equipment for oil draining. The main function of engine oil is to reduce friction and wear of moving parts and to remove sludge and paint from the engine.

What is the reason why the EPS light comes on and then goes away after restarting the engine?

If the EPS light comes on and then goes away after restarting the engine, it may be due to a sensor issue. In this case, you can check the vehicle's fault codes. Here is some information about EPS: 1. Definition: EPS refers to the electric power steering system in a car. If the EPS light illuminates on the dashboard while driving, it indicates a malfunction in the power steering system, which requires timely repair. 2. Classification: There are three types of power steering systems: HPS (Hydraulic Power Steering), EHPS (Electro-Hydraulic Power Steering), and EPS (Electric Power Steering). Among these, EPS is the most common type. The electric power steering system only provides power assistance when steering, and notably, the electronic steering system can be adjusted via software, making steering lighter when the car is moving at low speeds.

How to Check the Production Date of Great Wall Motor Oil?

Great Wall Motor Oil's production date is located at the bottom of the oil can. The first six digits represent the production date. Automotive lubricating oils are categorized into mineral lubricating oils, synthetic lubricating oils, semi-synthetic lubricating oils, and others. Under normal storage conditions—sealed at room temperature, protected from dust, water, and chemical fumes—Great Wall brand lubricating oil has a shelf life of approximately three years. Motor oil is used for lubricating internal combustion engines. Its primary functions include reducing friction and wear on moving parts, removing sludge and varnish from the engine, neutralizing acids produced by fuel combustion and lubricant oxidation, improving piston ring sealing, and cooling the engine by dissipating heat from moving components.
