What does 0w20 engine oil mean?

0w20 engine oil, the 'w' stands for winter. The number before 'w' represents the freezing point temperature, with common 0w indicating -35 degrees Celsius. The number after 'w' represents the kinematic viscosity of the oil at 100 degrees, with '20' being one of the lower grades in the oil classification. The composition of the oil grade includes two parts: classification and viscosity specification. The oil classification is represented by a combination of two letters. Those starting with 's' are for gasoline engines, those starting with 'c' are for diesel engines, and those with both 's' and 'c' are universal oils for both gasoline and diesel engines. The further the letter is in the alphabet, the higher the quality grade. The grade indicates the oil viscosity. The smaller the number, the better the fluidity in low-temperature environments, the lower the usable environmental temperature, and the better the protection for the engine during cold starts.

Where is the best position to stick the blind spot mirror?

The blind spot mirror should be attached to the lower left side of the left rearview mirror. When parking, vehicles usually stop on the right side of the road, and the left rearview mirror is less frequently used during reversing. The primary purpose is to minimize blind spots in the rearview mirror and also to see the right wheel. If installed on the right side of the rearview mirror, it may obstruct the view and increase driving risks. Disadvantages of blind spot mirrors: 1. Distance distortion - The small convex mirror used in the rearview mirror can distort distances while expanding the field of view, making it easy to misjudge distances while driving and increasing the likelihood of traffic accidents; 2. After installing a blind spot mirror, the driver's attention may be diverted, potentially overlooking surrounding conditions of the vehicle.

Where Are the Accelerator and Brake Pedals Located in a Car?

In a car, both the accelerator and brake pedals are located beneath the feet. The pedal on the right is the accelerator, and the one to its left is the brake. Both are controlled by the right foot. In emergency situations, if a person happens to have both feet on the brake and accelerator simultaneously, there is a high risk of making an incorrect judgment, such as mistaking the accelerator for the brake. Assigning control of both pedals to a single foot significantly reduces this possibility and also decreases the vehicle's lateral slip coefficient when braking while the accelerator is pressed. When operating the brake or accelerator, the body requires support to maintain balance. While the right foot is on the pedal, the left foot can stabilize the body by resting firmly on the floor. If both feet are placed on the brake and accelerator separately, they remain semi-suspended without a stable point of force, which can easily lead to unstable operation of either pedal.

How to Properly Use a Car Jack?

Methods for correctly using a car jack: 1. For manual transmission vehicles, engage the handbrake and shift the gearbox into 1st gear or reverse gear. For automatic transmission vehicles, also engage the handbrake and shift the gearbox to the P position; 2. Place the jack under the vehicle for lifting operation. When the top of the jack contacts the chassis, ensure that the support is properly positioned; 3. After confirming it is securely fixed, continue lifting and rotate using the accompanying wrench and sleeve. Precautions when using a car jack: 1. Never start the engine when the vehicle is lifted by the jack, as engine vibration or wheel rotation can cause the vehicle to slip off the jack, posing a danger; 2. When using the jack, always position it at the designated support points. Do not place the jack under the bumper, crossbeam, or other non-supporting parts; 3. Maintenance personnel must never work under a vehicle that is not properly supported. When changing a wheel, passengers should not remain in the vehicle, as movement can cause the vehicle to slip off the jack.

What is the Four-Wheel Alignment Function?

Four-wheel alignment function is based on the four-wheel parameters of the vehicle, and adjustments are made to ensure good driving performance and a certain level of reliability. Situations that require four-wheel alignment include: 1. The vehicle's driving performance is affected; 2. Damage to the chassis and suspension due to an accident; 3. Abnormal tire wear. The benefits of four-wheel alignment are: 1. Keeping the car stable in straight-line driving and making steering easier; 2. Ensuring that the rear wheels or front wheels can automatically return to the correct position after steering; 3. Reducing wear on tires and steering components during driving; 4. Maintaining the optimal driving angle between the tires and the vehicle body.
