E on the fuel gauge stands for empty, indicating low fuel level; F stands for full, representing a full tank. Additional relevant information is as follows: 1. When the needle points towards the F direction, it indicates more fuel, while the closer it is to E, the less fuel remains. Many vehicles have a red mark near the E on the fuel gauge, indicating that the fuel level is critically low and refueling should be done promptly. The fuel gauge is used to indicate the amount of fuel remaining in the vehicle's fuel tank, which can be displayed via a pointer or digitally. 2. The fuel gauge consists of a fuel level indicator with a voltage regulator and a fuel level sensor. The low fuel warning device is designed to illuminate and alert the driver when the fuel level in the tank falls below a certain threshold, drawing the driver's attention.

What to Do When the Windshield Wipers Stop Working?

Solutions for windshield wipers not working: 1. Open the fuse box, locate the wiper fuse, pull it out and replace it with a new one to resume operation; 2. Apply a layer of soap on the windshield, which can maintain clear visibility for about 30 to 40 minutes while driving; 3. If the wiper motor is faulty, it's unlikely to be fixed by yourself, so it's recommended to take the car to a repair shop. Some people believe that longer wiper blades provide better coverage and visibility, but in fact, longer blades are not necessarily better. While extending the length of the wiper blades can increase the visible range, it also adds extra burden to the wiper motor and wiper arm.

What Happens If Engine Oil Is Not Changed for a Long Time?

Not changing the engine oil for a long time will accelerate engine wear and affect engine performance, significantly reducing its sealing, lubrication, and cooling effects. The impurities in the oil will wear down internal components, thereby shortening the engine's lifespan and increasing the likelihood of malfunctions, which can pose safety hazards. Engine oil is often referred to as the 'blood' of the engine, as it plays crucial roles in cleaning, sealing, heat dissipation, lubrication, cushioning, and rust prevention within the engine. Over time, engine oil becomes thinner and deteriorates. Typically, full synthetic oil should be changed every 10,000 kilometers or once a year, semi-synthetic oil every 7,500 kilometers or every 7-8 months, and mineral oil every 5,000 kilometers or every 6 months.

Should Honda CR-V use 92 or 95 octane gasoline?

Honda CR-V uses 92 octane gasoline. Here is relevant information: Gasoline quality: Gasoline is produced and sold according to octane ratings, which are specified by national gasoline product standards and vary across different standards. China (V) standards include 89, 92, and 95 octane (with 98 octane in the appendix). Gasoline grades are classified by octane value. Fuel consumption reduction: The most cost-effective method to reduce fuel consumption is to increase the engine's compression ratio. Increasing the compression ratio only changes the piston stroke - the more the air-fuel mixture is compressed, the greater the combustion reaction, resulting in more complete combustion.

Will a Motorcycle Explode if Exposed to Direct Sunlight?

Under normal circumstances, a motorcycle will not explode when exposed to direct sunlight. Below is a detailed explanation of the potential hazards of prolonged sun exposure for motorcycles: 1. Components: The motorcycle's battery and electrolyte can be affected, as the sun may cause faster evaporation. Additionally, certain parts of the motorcycle, such as tires and seats made of rubber, will experience increasing temperatures under prolonged sun exposure, leading to gradual aging and reduced lifespan. 2. Vehicle: The paint on the motorcycle's surface may peel. Extended exposure to sunlight can cause the paint to soften and eventually flake off. This also contributes to a shorter lifespan for the motorcycle. Some rubber and plastic parts may age prematurely.
