What Vehicles Are Suitable for 85W-90 Gear Oil?

85W-90 gear oil is suitable for vehicles with manual transmissions. Gear oil should be replaced promptly according to regulations during use. Generally, after every 40,000 to 50,000 kilometers of driving, the oil should be changed in conjunction with regular maintenance. During the oil change, it is advisable to drain the old oil as much as possible and clean the gearbox. Below is additional information about 85W-90 gear oil: 1. Gear oil can be classified into single-grade viscosity types and multi-grade all-weather types. Single-grade viscosity types can be further divided into high-temperature and low-temperature types. 2. 85W-90 gear oil belongs to the multi-grade all-weather type, offering a broader practical temperature range and can be used year-round. 3. On the viscosity grade label of gear oil, 'W' stands for winter (low-temperature) gear oil. The number before 'W' indicates low-temperature viscosity—the smaller the number, the lower the viscosity, the better the fluidity, and the stronger the low-temperature performance. The number after 'W' represents high-temperature viscosity—the larger the number, the higher the high-temperature viscosity, and the greater the temperature resistance. 4. Appropriate gear oil viscosity ensures the formation of a sufficiently thick oil film under elastohydrodynamic lubrication conditions, providing the gear with adequate load-bearing capacity. However, the oil viscosity should not be too high, as excessive internal friction heat could lead to oil film rupture.

What can be used to clean automotive resin adhesive?

Automotive resin adhesive can be cleaned using water or alcohol. Below are specific details about resin adhesive: 1. Uses: It serves as the primary material for manufacturing fiberglass. After curing, it exhibits characteristics such as insulation, corrosion resistance, and heat resistance. Widely used in electrical appliances, shipbuilding, automotive industries, and other fields. Resin adhesive possesses strong bonding properties along with insulation, corrosion resistance, and heat resistance features. 2. Precautions: Prepared epoxy resin adhesive must be used entirely within the operable time. Exceeding 3 hours will cause the resin adhesive to solidify, affecting material properties. After application, it requires 5 hours to cure.

How long after the Subject 2 retest can you take Subject 3?

After the Subject 2 retest, you can take Subject 3 after an interval of 10-20 days. Below is the relevant exam information: 1. Scheduling Subject 3 more than 10 days after Subject 2 results: Each local vehicle management office has different regulations. If scheduling online, normally you can schedule Subject 3 immediately after the Subject 2 results are updated. However, scheduling often fails due to high demand, so many vehicle management offices require a waiting period of more than 10 days before scheduling. 2. Subject 3 content includes: vehicle preparation, light simulation test, starting, straight-line driving, gear shifting operations, lane changing, pulling over, going straight through intersections, left turns at intersections, right turns at intersections, passing pedestrian crossings, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and night driving.

What does 'mix' mean in a car?

In a car, 'mix' means random playback, while 'rpt' refers to repeat playback. Both are function buttons on the car audio system. Car audio system: The car audio system consists of five parts: antenna, receiver, speaker correction, audible frequency amplification, and speaker system. The car audio system is a playback device designed to alleviate the boredom of drivers and passengers during travel. The earliest version used was the car AM radio. Advantages: Car audio systems meet high standards in terms of sound quality, operation, and vibration resistance, ensuring stable performance and perfect sound quality even on bumpy roads. Tips for using car audio: Avoid using maximum volume: Every car audio system has a maximum volume limit, and the car's audio system often operates close to this limit. Prolonged use at maximum volume can damage the audio, leading to sound distortion or cracking. Additionally, in the confined space of a car, maximum volume can also harm hearing. Therefore, it's recommended to keep the volume output at around 80% of the maximum. Be careful when removing door panels to avoid damaging the audio: As electronic devices, vibrations and impacts are major causes of damage. Generally, audio systems are fixed in slots inside the door, so normal driving vibrations don’t harm them. However, when removing door panels for tasks like replacing soundproofing or repairing the audio, extra caution is needed. Handle the audio gently during removal; any impact or vibration from knocking the door panel can loosen or damage internal components. Protect from moisture and dust: Dust and moisture are deadly for most electronic devices. When cleaning the car interior, avoid using overly wet towels or spraying liquids like water or cleaners directly onto the speakers. For dust on the audio, use a dry towel or wet wipe. After cleaning the interior, ventilate the car to dry it before normal use. On rainy days, avoid opening windows to prevent rainwater from entering and wetting the speakers located in the doors and corners, which can cause water damage or moisture issues.

What are the penalties for using counterfeit license plates?

According to relevant regulations, the use of other vehicles' motor vehicle registration certificates, license plates, driving licenses, inspection qualification marks, or insurance marks will result in confiscation by the traffic management department of the public security authority, detention of the motor vehicle, and a fine ranging from 2,000 to 5,000 yuan. Additional information on handling counterfeit license plate cases: 1. For individuals: If a motor vehicle driver or owner discovers their vehicle's license plate has been counterfeited, they should promptly report to the traffic police department. When reporting, the affected party must present the vehicle's driving license, the owner's ID card, a copy of the driver's license, clear photos of the original vehicle from different angles (front and rear), and provide information on the suspected counterfeit vehicle, such as two copies of traffic violation notices received for the counterfeit vehicle (including violation time, offense, location, type of license plate, license plate number, and vehicle color). 2. For organizations: If the vehicle owner is an organization, the reporter must also hold an authorization letter from the organization. After verifying the vehicle information, the local public security and traffic police department will report to the relevant department of the Provincial Public Security Department's Traffic Management Bureau for system entry. Upon confirmation of the counterfeit license plate, on one hand, the traffic violation records of the affected vehicle will be cleared, and on the other hand, the counterfeit vehicle will be subject to long-term monitoring and strict enforcement measures, being included in a 'blacklist' database.

What are the penalty rules for parallel parking?

Parallel parking penalty standards are as follows: 1. Regulations: Driving over the parking space and lane lines with tires, deduct 20 points. After the vehicle is parked in the space, if the body extends beyond the parking space lines, deduct 20 points. If the vehicle is not properly aligned after parking, deduct 5 points. Failing to park in one forward and one reverse movement, deduct 20 points. Touching or scraping the poles, deduct 20 points. 2. New rules: After the implementation of the new traffic regulations, parallel parking no longer uses poles, and all parking space boundaries are marked with ground lines. For students learning C1 driver's license, the length of the parallel parking space is 1.5 times the vehicle length plus 1 meter. Drive the vehicle to the front of the parking space parallel to the direction of travel, then reverse into the space to the right rear without any pauses. As long as the vehicle is parked within this range without crossing the parking space lines, it is considered a pass.
