Here are specific details on when to replace engine oil: 1. Viscosity: Check the oil viscosity; if it lacks viscosity, the oil needs replacement. 2. Color: If the oil is black, it needs to be changed. 3. Impurities: Replace the oil when there are excessive black particles, metal shavings, or carbon deposits in the oil. 4. Smell: If the oil smells off, it should be replaced. Below is additional information on the functions of engine oil: 1. Reduces wear: It separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Heat dissipation: It carries heat back to the oil tank and then dissipates it into the air, helping the radiator to cool the engine. 3. Cleaning: It cycles carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, washing away dirt generated on the working surfaces of parts through the flow of the lubricating oil.

Can the wiper speed be adjusted if it's too fast?

It is possible to slow down the car's wiper if it's too fast. Below are the precautions for adjusting the car's wiper: 1. Avoid dry wiping: Always use the wiper when there is water on the windshield. Never operate it dry, as this can damage the rubber blade and the wiper motor. Therefore, ensure that the windshield washer fluid is always sufficient. 2. Pay attention to noise: The wiper motor is crucial. Be alert to any abnormal noises from the motor. If the motor hums but does not rotate, it indicates that the mechanical transmission part of the wiper is rusted or stuck. In such cases, immediately turn off the wiper to prevent the motor from burning out.

Is car film applied on the outside or inside of the car glass?

Car film is applied on the inside of the car glass, including the front windshield film, rear windshield film, side window film, and quarter window film. Benefits of car film: 1. Heat insulation and sun protection, reducing the temperature inside the car; 2. UV protection, reducing the aging of car interiors; 3. Preventing injuries to passengers from accidental glass breakage; 4. Maintaining privacy and safety. Steps for applying car film: 1. Lay towels on the front hood and dashboard; 2. Put on seat covers and wrap them tightly with plastic wrap; 3. Clean the glass thoroughly; 4. Slide the soft template over the car window glass for positioning, then cut the window film according to the template.

What are the causes of insufficient fuel pressure?

Insufficient fuel pressure can be caused by: 1. Internal blockage of the high-pressure fuel pump or malfunction of the pressure regulator; 2. The cold start solenoid valve stuck in the normally open position; 3. Damaged fuel injectors, leading to excessive fuel return or large amounts of fuel leaking into the cylinders; 4. Bends, collapses, or blockages in the low-pressure fuel line causing poor fuel supply; 5. Incorrect signals from the pressure sensor; 6. Damage to the electric fuel pump. The effects of insufficient fuel pressure include: 1. Increased likelihood of fuel line blockages or leaks, clogged fuel filters, faulty overflow valves, or excessively low pressure regulation; 2. Reduced fuel supply, which affects idle speed and acceleration.

Can You Continue Driving with a Flat Tubeless Tire?

You should not continue driving on it and should promptly go to an electric vehicle repair point for maintenance. Below is relevant information about tubeless tires: 1. Safety Performance: One advantage of tubeless tires is that when a sharp object punctures them, as long as the object is not removed, the tire will slowly leak air instead of quickly losing all air like a tire with an inner tube. 2. Additional Information: Tubeless tires, also known as "low-pressure tires" or "pneumatic tires," have high elasticity and wear resistance, along with good adhesion and heat dissipation performance. This is especially true for all-steel radial tubeless tires, which are economical and durable.
