How to Clean Off Engine Oil?

The methods for cleaning engine oil are: 1. Use alcohol for cleaning, as alcohol can dissolve in both organic solvents and water, with higher concentrations being more effective; 2. Apply a small amount of essential balm to the area of clothing stained with engine oil, wait a few seconds, then wash; 3. Use gasoline for cleaning—first wipe with gasoline, and for heavier stains, use mineral spirits and turpentine. Once the stain dissolves, proceed with regular washing. Engine oil, also known as motor lubricant, serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Engine oil consists of base oil and additives. The base oil is the primary component of the lubricant, determining its basic properties, while additives compensate for and improve any shortcomings in the base oil's performance, adding new characteristics, making them an essential part of the lubricant.

What is the solution for the brake light staying on?

The solutions for the brake light staying on are: 1. Check the brake fluid and replenish it in time if it is insufficient; 2. Inspect the brake switch and repair it after disassembly; 3. Examine the brake pads for wear and aging, and replace them if their thickness is below the specified value. The reasons for the brake light staying on include: 1. Brake pads worn to the limit; 2. Insufficient brake fluid; 3. Short circuit in the warning circuit; 4. Damaged ABS pump; 5. Handbrake not released or switch short circuit; 6. Damaged brake light switch on the brake pedal. The brake light is installed at the rear of the vehicle, with a red main body color to enhance the light's penetration, ensuring that following vehicles can detect the braking of the vehicle ahead even under low visibility conditions, thereby preventing rear-end collisions.

What does 4WD on the back of a car mean?

4WD on the back of a car stands for Four-Wheel Drive, also known as All-Wheel Drive. It means that both the front and rear wheels of the car are powered, and the engine's torque can be distributed in different proportions to all wheels according to the road conditions to improve the vehicle's driving capability. Four-wheel drive systems are divided into two main categories: active and passive, but the goal is the same—to transfer power from the wheels that are spinning or slipping and redistribute it to the wheels with better traction. The four-wheel drive system in passenger cars is a full-time system, which includes a viscous coupling that eliminates the need for a manual transfer case, automatically distributing torque between the front and rear wheels as needed. On normal road surfaces, the four-wheel drive system distributes 92% of the engine's torque to the front wheels and 8% to the rear wheels.

How long after car window tinting can you roll down the windows?

After car window tinting, you can roll down the windows after 3 days in summer, while in winter when temperatures are lower, it's recommended to wait 7 days. Due to differences in installation techniques, the appropriate time to open windows may vary. It's advisable for car owners to consult the installers after the tinting is completed to avoid any abnormalities during use. The thermal insulation film requires a certain period to firmly adhere to the windows. Opening and closing the windows during this period may cause the edges of the newly applied film to peel or the incompletely bonded film to shift. Precautions after car window tinting: 1. Avoid washing the car immediately after tinting; 2. Don't rush to open the windows; 3. Seek professional help promptly if bubbles appear in the film.

How to Check the Production Date of Tires?

Method to check the production date of tires: The manufacturing date of a tire can be found on the outer side of the tire. There is a set of four-digit numbers in an elongated oval shape at the end of the letters. The first two digits represent the week of the year, and the last two digits represent the year. Tires are circular elastic rubber products assembled on various vehicles or machinery for rolling on the ground. Tires are usually mounted on metal rims to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires serve as the medium for transmitting forces between the vehicle and the road surface, transmitting driving force, braking force, steering force, etc., to realize the vehicle's driving, braking, steering, and other operations.

What happens if you put 95 gasoline in a car that requires 92?

Generally, there is not much impact if you put 95 gasoline in a car that requires 92, but using higher-octane gasoline will not increase power because the engine's compression ratio does not meet the standard. After switching to 95, the anti-knock performance will definitely be better than before, naturally preventing knocking, and fuel consumption will basically remain unaffected. The main function of gasoline octane ratings is to indicate anti-knock performance, and it has no relation to the quality of the gasoline itself. It is not true that higher-octane gasoline contains fewer impurities. The anti-knock substance in fuel is isooctane, with 92-octane gasoline containing 92% isooctane. Higher-octane gasoline offers better combustion stability, preventing the engine from malfunctioning due to knocking, which is why engines designed for 95-octane gasoline should not use 92-octane gasoline.
