What Oil to Use in All Seasons?

For all seasons, oil grades such as 5W40, 5W30, 5W20, 0W40, 0W30, 0W20, etc., can be used. The classification of oil and the reasons for the oil light to come on are as follows: Oil Classification: Oil grades are represented by a combination of two letters. The 'S' series represents oil for gasoline engines, with specifications ranging from SA to SN in alphabetical order, skipping SI, with each increment representing a higher grade. The 'C' series represents oil for diesel engines. If both 'S' and 'C' letters are present, it indicates that the oil is suitable for both gasoline and diesel engines. Reasons for the Oil Light to Come On: High engine temperature can thin the oil, causing it to leak excessively through the clearances and leading to a drop in oil pressure. Insufficient oil quantity reduces the oil pump's output or prevents it from pumping oil due to air intake, resulting in decreased oil pressure. Improper clearance between the crankshaft and the main or connecting rod bearings—too tight increases oil pressure, while too loose decreases it, among other reasons.

How Much Transmission Fluid Should Be Added?

Generally, about 4 liters of fluid are needed. The types of transmissions and precautions for transmission break-in are as follows: Types of transmissions: AT transmission, which is a hydraulic automatic transmission. CVT transmission, which is a mechanical continuously variable automatic transmission. AMT transmission, which is an electronically controlled mechanical automatic transmission. Dual-clutch transmission, which has two sets of clutches inside the transmission. Manual transmission. Precautions for transmission break-in: Shift gears promptly while driving, especially avoiding lugging the engine. Lugging increases the engine load and causes impact on the engine, suspension, and chassis. Some cars equipped with intelligent transmissions will have the transmission learn the driver's habits during the first 500km of the break-in period. The transmission's computer will calculate an optimal working mode to improve the car's comfort and fuel efficiency. Therefore, it is best not to frequently change drivers during the first 500km of the break-in period to allow the intelligent transmission to adapt to the learning process.

When are the mandatory turn signal locations in Subject 2?

There are three instances in Subject 2 where turn signals must be used: exiting a parallel parking space (left turn signal), making a 90-degree turn (left turn signal), and stopping at a designated point on an uphill slope (right turn signal). Penalties for incorrect use of turn signals are as follows: Failure to use or incorrect use of turn signals before starting, turning, changing lanes, overtaking, or parking results in a 10-point deduction. Using the turn signal for less than 3 seconds before starting, turning, changing lanes, overtaking, or parking results in a 10-point deduction. The full score for Subject 2 is 100 points, with evaluation criteria set for failure, 20-point deduction, 10-point deduction, and 5-point deduction. The test is considered passed under the following conditions: ① For applicants of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. The test items for small vehicles C1 and C2 include reversing into a garage, parallel parking, stopping and starting on a slope (canceled for C2), 90-degree turns, and driving through curves (commonly known as S-turns) as the five mandatory items (some regions include a sixth item: highway toll card collection). The test items for large vehicles A1, A2, A3, B1, and B2 include pole test, stopping and starting on a slope, parallel parking, driving over a single-plank bridge, driving through curves, 90-degree turns, passing through a width-restricted gate, driving over continuous obstacles, driving on bumpy roads, making U-turns on narrow roads, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rain (fog) conditions, slippery roads, and emergency handling.

How to Drive on the Highway with Temporary License Plates?

To drive on the highway with temporary license plates, you simply need to hang the temporary plates in the designated positions, which is no different from driving with regular license plates. As long as the plates are within their validity period, you can drive in all regions, but you must carry all relevant documents such as the invoice, certificate of conformity, and proof of insurance purchase. To apply for temporary license plates, you must meet one of the following conditions: (1) When driving the vehicle from the place of purchase to another location, you need to apply for temporary plates at the local vehicle management office where the vehicle was purchased. (2) When transferring vehicle registration and after surrendering the regular license plates, you need to apply for temporary plates at the local vehicle management office to drive back to your home location. (3) If a new vehicle in the local area has not been issued regular license plates and needs to be driven to another location for modifications, you must apply for temporary plates locally. After modifications are completed, apply for temporary plates at the modification location to drive back to the original area.

How many days after passing the driving test can I take the written test without an appointment?

Subject 4 (written test) can be taken on the same day as passing Subject 3 (road test) without an appointment. As long as one hour has passed after passing Subject 3, you can go take the test. In some regions, you can directly take Subject 4 and receive your license on the same day after passing Subject 3. However, in some areas, you need to wait three days after passing Subject 3 before you can start making an online appointment. This only applies to the first attempt at Subject 4. If you fail the first attempt, you must wait 10 days before you can make another appointment. In some places, there are certain conditions for taking Subject 4 without an appointment. Within 9 days after passing Subject 3, you can go to the Subject 3 safety and civility test center with your original ID card to take the safety and civility test (Subject 4). After 9 days, you need to make an appointment through the 12123 app or the traffic safety management service platform. Below are the reasons why you might not be able to make an appointment for Subject 4 on 12123: 1. Insufficient or invalid study hours: You must complete 10 study hours for Subject 4, with no more than 4 hours per day. Only after completing the hours can you make an appointment. Invalid study hours may occur if you are simultaneously training for other subjects, such as studying Subject 1 theory and Subject 4 theory at the same time, or training for Subject 1 and Subject 2 simultaneously. It is recommended not to study different subjects on the same day. Photo discrepancies can also easily lead to invalid study hours. If the photo taken during training differs too much from the photo taken during registration due to posture, angle, or makeup, the system may deem the photos inconsistent. 2. Not meeting the exam cycle: Generally, after passing Subject 3, you must wait for an exam cycle before you can make an appointment for Subject 4. The exam cycle varies depending on the efficiency of different regions, usually around 10 days. Whether you can successfully make an appointment also depends on the number of applicants, exam capacity, and your ranking in the registration queue. Therefore, there is no exact time for how soon you can take Subject 4.

Where is the drain screw of the GuoBin 650 located?

The drain screw is located at the very bottom of the carburetor. Method to open it: Loosen it to drain the gasoline inside the carburetor. The fuel tank switch handle in a horizontal position means it is closed. Move the fuel tank switch handle upwards for the reserve tank and downwards for the main tank. Location of the drain screw on other models: For scooter motorcycles, the carburetor drain screw is at the bottom of the carburetor. You need to remove the carburetor or loosen the intake pipes in front of and behind the carburetor, then tilt the carburetor significantly to the right to see and loosen the drain screw. Failure to start: This might be caused by the carburetor being clogged with sticky residues formed by evaporated and deteriorated gasoline, preventing fuel injection. The carburetor needs to be removed and thoroughly cleaned, ensuring all the spray holes inside the carburetor are unclogged for the engine to start.
