What does the E and F on the fuel tank represent?

E and F represent the volume of the car's fuel tank. On the fuel gauge of the car's dashboard, the characters E and F are used. F stands for full, and E stands for empty. If the fuel gauge needle is at the F position, it means the car's fuel tank is full. If the fuel gauge needle is at the E position, it means the fuel tank is almost empty. When the car is low on fuel, a warning light will illuminate on the dashboard. The fuel warning light is usually shaped like a fuel tank. When fuel is low, the warning light will turn yellow; in cases of extremely low fuel, the warning light will turn red. Some car models only display a yellow fuel warning light, in which case the owner should pay attention to the remaining fuel level and refuel in time. During the refueling process, it is not advisable to fill the car's fuel tank to the brim, especially in hot summer weather. This is because gasoline expands and evaporates into vapor under high temperatures, and the resulting vapor or even liquid can enter the carbon canister for storage. Overfilling the tank can cause deviations in the fuel gauge needle. Even after prolonged use, the fuel gauge needle may not drop and will only return to normal after some time. Effects of low fuel levels: Fuel sloshing causing the car to stall: When the fuel level is too low, on bumpy or winding roads, the fuel can slosh around, and the fuel pump may not be able to pump fuel in time. This can lead to insufficient fuel supply, causing the car to experience jerking, hesitation, or stalling. Fuel pump overheating: The fuel pump is cooled by the fuel. If the fuel level is too low, the cooling performance of the fuel pump decreases, accelerating wear on internal components and potentially leading to short circuits or burnout. Clogging the fuel system: The bottom of the fuel tank contains more impurities. If the fuel level is too low, these impurities can enter the fuel supply system due to fuel sloshing, leading to clogged fuel lines. Affecting driving safety: Low fuel levels can easily cause the car to stall. If the car stalls while driving, both steering and braking can be affected. If there is heavy traffic on the road, this can lead to traffic accidents.

What is the difference between 75w80 and 75w90?

Generally, cars use 75W-90 which is suitable for all seasons. More accurately, you should follow the specifications in your vehicle's manual. 75W indicates low-temperature performance with a minimum operating temperature of -42°C, while 90 represents the viscosity at high temperatures. 75W-80 has relatively lower viscosity. Typically, the lubricating oil used for transmissions and rear axle gear transmission mechanisms is called gear oil. The contact stress and relative sliding speed on the tooth surface engagement part vary greatly depending on the mutual position of the gear axes and the tooth profile, thus requiring different types and varieties of gear oil. Viscosity grades of gear oil: 1. Classification: According to the kinematic viscosity at 100°C and the maximum operating temperature when the apparent viscosity is 150,000 mPa.s, it is divided into seven viscosity grades (brands): 75W, 75W/90, 80W/90, 85W/90, 90, 85W/140, and 140. 2. Ordinary vehicle gear oil: Suitable for manual transmissions and spiral bevel gear drive axles under moderate load and speed with relatively harsh conditions. Divided into three specifications based on viscosity: 80W/90, 85W/90, and 90. The 90-grade oil can be used year-round in areas south of the Yangtze River. 3. Medium-duty vehicle gear oil: Suitable for gears operating under low-speed high-torque and high-speed low-torque conditions, as well as drive axles with hypoid gears under less harsh conditions. Divided into five specifications based on viscosity: 75W, 80W/90, 85W/90, 90, and 85W/40, among which the 90-grade oil can be used year-round in areas south of the Yangtze River.

Can I Upgrade to Higher Specifications Through Insurance?

You can upgrade to higher specifications through insurance. Here is an introduction to purchasing insurance: 1. Purchasing Method: Car insurance can be reasonably purchased according to the owner's needs, either at a 4S store or elsewhere. 2. Buying a Car with a Loan: Generally, when buying a car with a loan, insurance must be purchased in-store, and a certain renewal deposit may be charged. 3. Compulsory Traffic Insurance: This is a mandatory insurance in China, and all vehicles must purchase this type of insurance. 4. Insurance Coverage: If the vehicle involved in an accident has compulsory third-party liability insurance, the insurance company will cover the rescue costs within the liability limits.

What does SYS mean on a car?

The SYS on the car dashboard is the abbreviation of the English word 'system', indicating a general engine system fault. Here is an introduction to engine-related content: 1. Energy conversion: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. 2. Device: An engine can refer to both the power generation device and the entire machine including the power device (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of the engine also originates from English, and its original meaning refers to 'a mechanical device that generates power'.

Can a C2 driver's license drive a semi-automatic transmission car?

Yes, a C2 driver's license can drive a semi-automatic transmission car. Relevant information is as follows: 1. Definition of semi-automatic transmission: Semi-automatic transmission cars also belong to the category of automatic transmission cars. As long as there's no clutch pedal and only brake and accelerator pedals, it's considered an automatic transmission car. 2. Advantages of semi-automatic transmission: Semi-automatic transmission combines manual gear shifting and automatic gear shifting. Manual transmission allows free adjustment of gears and RPM. The semi-automatic transmission is designed to improve the fuel efficiency and controllability of automatic transmissions by returning the gear shift timing (originally determined by computer) back to the driver's control. Meanwhile, in urban traffic congestion situations, drivers can still use automatic mode for easier operation.

What are the tools for car tire repair?

Car tire repair tools are as follows: 1. Tire removal machine: This is an essential device for tire repair. Without this equipment, tubeless tires cannot be removed from the rims. 2. Tire grinding machine: Since tires may wear unevenly due to misalignment, this machine can grind them to the same level of wear, extending the tire's lifespan. 3. Tire repair patches and glue: Generally divided into hot-press patches and cold-press patches. Hot-press patches require heating for use, making them more durable but also more expensive. 4. Dynamic balancer: This is used to perform dynamic balancing on the tire after repair, ensuring the tire rotates around its center of gravity. 5. Air compressor: After repairing the tire, this machine is used to inflate the tire.
