What Does 10w40 Engine Oil Represent?

Engine oil labeled 10w-40 indicates that the number 10 represents the minimum applicable temperature of the oil, which is -25 degrees Celsius; W stands for all-season use in both summer and winter; 40 represents the high-temperature viscosity of the oil, with higher numbers indicating thicker oil at high temperatures. Below is relevant information: 1. 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. 2. The SAE viscosity grades for winter oils are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W stands for winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. 3. The SAE viscosity grades for summer oils are: 20, 30, 40, 50. The higher the number, the greater the viscosity, and the higher the applicable maximum temperature.

Can Ground Tread Tires Be Used?

Ground tread tires are tires with removed barcodes. They should not be used for frequent highway driving. Other vehicles can use ground tread tires. Ground tread tires refer to tires where the white barcode located at the tire toe area has been ground off. Detailed information about ground tread tires is as follows: 1. Ground tread tires are defective tires: Tires with ground-off barcodes are not genuine products, and manufacturers will not take responsibility for any issues. Additionally, these tires are non-warranty products, being substandard items identified during factory inspections. Ground tread tires with minor defects can still be used. 2. Ground tread tires are cheaper but may have dynamic balance issues: Dynamic balance problems in ground tread tires can be corrected through balancing procedures. While dynamic imbalance won't cause tire blowouts, it can lead to side-to-side wobbling. They can be used normally at lower speeds and without heavy loads. 3. When purchasing ground tread tires, it's best to choose reputable brands: Most ground tread tires from major brands only have dynamic balance issues. Many generic brand ground tread tires may have numerous problems, such as uneven rubber content, radial issues, tire peeling, or small holes in the tires.

How to Install an External Tire Pressure Monitor?

Unscrew the dust cap of the air valve, then put on the dust cover, install the hex nut, mount the tire pressure sensor, and tighten the sensor with a nut wrench to complete the installation of the tire pressure sensor. The following are the functions of a car tire pressure monitoring system: Extend Tire Lifespan: With a tire pressure monitoring system, you can always keep the tires working within the specified pressure and temperature range, thereby reducing tire damage and extending tire lifespan. More Economical Driving: When the tire pressure is too low, it increases the contact area between the tire and the ground, thereby increasing friction resistance. When the tire pressure is 30% below the standard value, fuel consumption will increase by 10%. Reduce Suspension Wear: Inconsistent tire pressure between the left and right tires is like parking on uneven ground. Long-term parking can cause uneven wear on the left and right suspension of the car. At the same time, when the tire pressure is too high, the tire's own shock absorption effect is reduced, increasing the burden on the vehicle's shock absorption system. Long-term use can cause significant damage to the engine chassis and suspension system. If the tire pressure is uneven, it can also easily cause the car to pull to one side when braking, thereby increasing wear on the suspension system.

How to Adjust the Rearview Mirrors for Subject Two of the Driving Test?

Here are the adjustment methods for the rearview mirrors in Subject Two: 1. Take the right-side parking as an example: the car body should occupy half of the mirror, the rear door handle should be 1 centimeter below the top edge of the mirror, and the front door handle should be about one-third from the bottom edge of the mirror. 2. The method for adjusting the left mirror is the same as the right mirror, but the car body can occupy slightly more space. The rear door handle should be near the top edge of the mirror, ensuring that you can see the left rear wheel without leaning out of the window. This facilitates observation during left-side parking and parallel parking. Additional Tips: The rhyme for adjusting the rearview mirrors in Subject Two: The front door handle is in the middle, the rear door handle is at the top, and the car body occupies one-third of the mirror. The two arrows point to the two door handles, and the adjustment methods for the left and right mirrors are the same. The key to passing Subject Two is controlling the speed and accurately spotting the points and lines on the test field.

What are the features of the 2021 Hongqi H5?

Appearance: The Hongqi H5 boasts a striking and imposing design that still retains a touch of elegance. Driving on the road, the Hongqi H5 is sure to turn heads. Rich configurations: The interior of the Hongqi H5 follows a sophisticated route, featuring a panoramic sunroof, three-color adjustable ambient lighting, driver's seat memory function, front and rear leather seats, and a variety of trendy configurations. Poor seat comfort: The middle seat in the rear of the Hongqi H5 is significantly higher than the two sides, making passengers feel like they are riding a horse when seated in the middle, which is very uncomfortable. Additionally, loud noise and the installation of privacy glass on the rear side of the sport version are two drawbacks of the Hongqi H5. High fuel consumption and low cost-effectiveness: The Hongqi H5 is equipped with a 1.8T turbocharged engine, delivering a maximum power of 178 horsepower and a peak torque of 250 Nm, paired with a 6-speed automatic transmission. This power configuration is too fuel-consuming, and without an absolute price advantage, the high fuel consumption directly lowers its cost-effectiveness.
