What Grade of Engine Oil Should Be Used in Winter?

In northern regions, using 5W-30 viscosity engine oil in winter should be fine. Engine oil starting with 5W can be used in low-temperature environments above -30 degrees Celsius. In Jilin area, winter temperatures are around -20 degrees Celsius, so 5W-30 viscosity engine oil is suitable. Here are some related introductions about engine oil: 1. In regions where winter temperatures drop below -20 degrees Celsius, it is recommended to use engine oil starting with 0W. 0W engine oil can handle low temperatures around -35 degrees Celsius, with better low-temperature fluidity than 5W, making it easier to start the engine during cold winter starts. The 30 viscosity needs to be selected based on the vehicle model, as different brands of vehicles have certain differences in requirements for oil viscosity and certification standards. It is best to choose engine oil according to the manufacturer's requirements. 2. Engine oil used in winter must meet three main characteristics: low viscosity, low pour point, and good anti-wear properties to provide excellent protection for the engine. Winter temperatures are relatively low, so the fluidity of engine oil in cold conditions is poor. Some engine oils may even solidify in environments below -10 degrees Celsius, so winter engine oil needs to have good low-temperature fluidity.

Can Mainland Vehicles Drive on the Hong Kong-Zhuhai-Macao Bridge?

Generally, Mainland vehicles are not allowed to drive on the Hong Kong-Zhuhai-Macao Bridge without proper procedures. The required steps are as follows: 1. Step 1: Prepare the application for commercial vehicle license plates. 2. Step 2: Eligible applicants can submit the required documents through the online service portal of the authorities. Documents required for Mainland vehicles to drive on the Hong Kong-Zhuhai-Macao Bridge: (1) Application form for cross-boundary vehicle movement and driver's permit between Guangdong, Hong Kong, and Macao. (2) Vehicle registration certificate and proof of ownership, with the vehicle owner matching the applying company. (3) Copies of the driver's ID card, Hong Kong driver's license, and Mainland driver's license. (4) The driver's travel permit to Hong Kong and Macao, which must include multiple-entry business endorsements under the company's name, matching the applicant's company. (5) One color photo of the vehicle (88mm×60mm, taken from a 45-degree angle on the left front side) and one recent passport-sized color photo of the driver (white background, front view without a hat).

Should the straight-going vehicle yield to the lane-changing vehicle or vice versa?

The lane-changing vehicle should yield to the straight-going vehicle. Here is the relevant information: 1. Precautions for lane changing: When entering the driving lane from the acceleration lane, pay attention to observe the situation in the driving lane. When the traffic is sparse, enter the driving lane from behind the normally moving vehicles; when the following distance of a normally moving vehicle is relatively close, control the speed and enter the driving lane only after all vehicles have passed. Do not abruptly cut in from the middle. Turn signals must be activated in advance before changing lanes. When turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, the left turn signal should be activated in advance; when turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside, the right turn signal should be activated in advance. 2. Penalties for illegal lane changing: Driving a motor vehicle on a highway or urban expressway without following the prescribed lane will result in a 3-point penalty; when encountering a queue of parked or slowly moving vehicles ahead, overtaking by borrowing the opposite lane or cutting into the queue will result in a 2-point penalty.

Will the small white spots disappear by themselves after film application?

Small white spots after film application will not disappear by themselves. The small white spots are caused by impurities such as dust, hair, etc., which create slight bulges and leave trapped air, resulting in the white spots. Here are some precautions regarding film application: 1. Venue requirements: The film application site must be kept clean, avoid using electric fans, and never perform the application by the roadside. 2. Surface cleanliness: The car window glass must be absolutely clean, requiring repeated cleaning. Any remaining dust particles on the glass will severely affect the adhesion and clarity of the sun film. 3. Sun film placement: The sun film should only be applied to the inner side of the glass. 4. Pre-shaping for curved surfaces: Applying the sun film to flat side windows is relatively easy, but applying it to the curved front and rear windshields requires high technical skill. Generally, the outer surface of the front and rear windshields is used as a mold to heat and pre-shape the sun film.

How to Use Car Coating Agent?

Car coating agent is used as follows: The car coating process involves applying the coating product evenly onto the car paint surface using a specialized spray gun, based on traditional polishing techniques. Then, a specialized sponge is used to spread the liquid solution uniformly over the car body in a spiral motion, followed by wiping with a pure cotton towel. Below is an introduction to the coating process: 1. After car coating, the paint surface exhibits enhanced oxidation resistance, wear resistance, corrosion resistance, and high-temperature resistance. The coating layer is more evenly distributed, finer, harder, and maintains a longer-lasting shine. It transforms the car paint into a continuous surface, increasing the overall paint density. 2. It also provides excellent layering performance, meaning that even after multiple layers, there is no interface between layers, and no 'peeling' phenomenon occurs. When the product is applied to the car paint surface, under natural conditions, the molecular structure undergoes a remarkable transformation due to the action of silicone, changing from a chain structure to a cross-linked network structure between molecular chains, thereby protecting the car paint. This change in molecular structure enhances the product's physical, chemical, and mechanical properties. 3. This results in an ideal effect of long-lasting brightness, a silky touch, and a luxurious appearance, emitting a unique glow similar to sunlight reflecting on water.

How to Identify the Number of Pistons in a Brake Caliper?

There are several circular protrusions on the brake caliper, and these protrusions are the pistons. Multiply the number of protrusions on one side by four to calculate the total number of pistons. Below is an introduction to brake calipers: 1. The brake caliper is part of the automobile braking system and belongs to a type of disc brake. Disc brakes are further divided into solid disc and ventilated disc types, with most modern cars using ventilated disc brakes. Ventilated disc brakes consist of a brake disc, friction pads, brake booster pump, wheel cylinder, and brake caliper. The piston caliper is the device that pushes the friction pads against the brake disc; generally, the number of piston calipers corresponds to the number of friction pads. 2. More friction pads mean a larger friction area, and a larger friction area results in greater friction with the brake disc. Knowing that pistons are equivalent to friction pads, it follows that more pistons indicate better braking performance. 3. The working principle of the braking system is that when the driver presses the brake pedal, brake fluid begins to apply pressure. The brake fluid is transmitted through the pipelines to the pistons of each brake assembly, and the pistons drive the brake caliper to initiate braking. The function of the pistons is to increase the force-bearing area of the brake disc, so more pistons mean a larger friction area on the brake disc.
