Diesel engine oil grades include 0W, 5W, and 10W. Increased fuel consumption: When adding engine oil, the oil level should be between the upper and lower limits on the dipstick. If too much oil is added, the oil volume will expand as the engine temperature rises, increasing the pressure in the oil chamber and operational resistance. This can lead to reduced vehicle power and increased fuel consumption. Overfilling oil: Excessive oil can cause oil to leak through the crankcase vent pipe. Increased crankcase pressure may loosen the oil seals due to oil pressure, resulting in oil leaks. Heat dissipation: Overfilling oil can affect engine heat dissipation.

How Many Chances Are There for Subject Two and Three?

For Subject Two and Subject Three, each appointment allows one examination attempt. If the examinee fails, they can take a make-up exam on the spot. If they do not take the make-up exam or still fail the make-up exam, the current examination is terminated, and the applicant must reschedule the exam after ten days. Within the validity period of the driving skill test permit, the number of appointments for the Subject Two and Subject Three road driving skill tests must not exceed five. If the fifth scheduled exam is still failed, the passing scores of other subjects already taken will be invalidated. Subject Two is scored out of 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The exam is considered passed if the following conditions are met: ① For applicants applying for large buses, trailers, city buses, medium buses, or large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. Subject Three is scored out of 100 points, with a passing score of 90. The exam generally includes: vehicle preparation, simulated lighting test, starting, driving in a straight line, gear shifting operations, changing lanes, pulling over, proceeding straight through intersections, turning left at intersections, turning right at intersections, crossing pedestrian crosswalks, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and nighttime driving.

What are the reasons for the parking brake system failure causing the car not to start?

The reasons for the parking brake system failure causing the car not to start are as follows: the brake light switch has a problem, causing the ECU to not receive the normal startup power signal. The parking brake is a device used to stabilize the vehicle after it has come to a stop, preventing accidents caused by the vehicle rolling on sloping roads. The operation method of the parking brake depends on the transmission type: 1. Manual transmission: When applying the parking brake, step down on the brake pedal and pull up the parking brake lever. When starting, step down on the brake pedal, slightly pull up the parking brake lever, press the button at the front end of the handle, and lower the parking brake lever completely. 2. Automatic transmission: After applying the parking brake, move the gear lever to the P position. When preparing to start, shift the gear lever to the drive position before releasing the parking brake.

What does the STOP fault code mean?

The STOP light in a car is a mandatory parking alarm light, which typically illuminates simultaneously with one of the warning lights such as low oil pressure, low brake fluid level, or high coolant temperature, indicating that the engine must be stopped immediately. Please shut down the engine as soon as possible and promptly troubleshoot the issue. Do not start the engine until the fault is resolved. Specific faults need to be diagnosed using a diesel decoder. Low engine oil pressure can lead to poor lubrication, increased cylinder wear, and in severe cases, engine bearing seizure, causing the engine to malfunction. High engine oil pressure accelerates premature wear of the oil pump and results in excessive oil consumption. High coolant temperature is detrimental to fuel efficiency and increases component wear. When the temperature exceeds 90°C, the engine power decreases accordingly. Excessively high temperatures can also cause detonation, leading to a series of issues such as cylinder scoring, cylinder head gasket damage, and component deformation. Brake system failures may result in sudden brake failure, brake pull, or brake vibration. If the brake system malfunctions, you must stop driving immediately. Continuing to drive may lead to traffic accidents.

Does windshield washer fluid have an expiration date?

Windshield washer fluid does have an expiration date, and the shelf life may vary among different brands, but it is generally 2 or 3 years. Here is some information about windshield washer fluid: 1. High-quality windshield washer fluid is made from deionized water and various environmentally friendly additives, featuring functions such as cleaning, antifreeze, antistatic, and anti-corrosion. Some premium washer fluids even offer additional benefits like rapid snow and ice melting, anti-glare, and anti-fog properties, which significantly enhance driving safety. 2. If the washer fluid has expired, it is recommended not to use it. No matter how good the washer fluid is, once it expires and deteriorates, it loses its intended effectiveness. 3. Therefore, when purchasing washer fluid, car owners should first check whether the product is within its expiration date, and secondly, look for any sediment in the fluid, as its presence indicates that the washer fluid has deteriorated.
