What Causes Large Vehicles to Leak Engine Oil?

Possible causes of engine oil leakage in vehicles include aging, damage, or failure of the bottom engine seals, or the engine bottom being scraped by rocks. Engine oil leakage leads to a reduction in oil levels, resulting in insufficient lubrication, accelerated internal engine wear, reduced engine lifespan, and in severe cases, may cause significant engine damage or even engine burnout. Solutions: Oil seals and gasket damage or aging: Replace with new sealing components. If the leakage persists, remove the shock absorber. If there is any sticking or uneven resistance, further inspect the gap between the piston and cylinder for excessive clearance, and check for any bending in the shock absorber piston rod. Valve stem seals: Valve stem seals prevent oil from entering the intake and exhaust pipes, which would lead to oil loss. They also prevent the leakage of the air-fuel mixture and exhaust gases, and stop engine oil from entering the combustion chamber. Most cases of "oil burning" are caused by faulty valve stem seals. Hazards of Oil Leakage: The amount of engine oil is closely related to vehicle performance. Insufficient oil can lead to bearing seizure, cylinder scoring, and in severe cases, crankshaft breakage and engine block damage. Excessive oil affects the vehicle's power and can cause oil carryover and burning. Therefore, engine oil should be added according to the standard specifications for the vehicle model.

What is the oil change interval?

The oil change interval is between 5,000 to 10,000 kilometers. Conventional oil needs to be changed at around 5,000 kilometers. Below is relevant information about engine oil: Oil change interval: Engine oil should be changed every 5,000 kilometers traveled. The duration oil can last depends on its quality. High-quality oil can last up to a year without issues, while regular oil typically lasts about six months. Engine oils are categorized into mineral oil, semi-synthetic oil, and full synthetic oil, each with different change intervals. Generally, mineral oil should be changed every six months or 5,000 kilometers, semi-synthetic oil every six months or 7,500 kilometers, and full synthetic oil every six months or 10,000 kilometers. Functions and replacement method of engine oil: It separates the surfaces of relatively sliding parts to reduce wear; carries heat back to the oil pan and dissipates it into the air to help the radiator cool the engine; cycles carbon deposits, sludge, and wear particles from engine parts back to the oil pan, flushing away contaminants generated on the parts' working surfaces through the flow of the lubricating oil. Use a jack to lift the vehicle and drain the old oil; remove the oil filter; install a new oil filter and refill with new oil.

What Causes the Buzzing Sound When Turning the Steering Wheel?

Car steering wheel buzzing is related to the shock absorber pressure bearing, and the damage to the pressure bearing is largely connected to the operation technique. If the abnormal sound comes from inside the steering wheel, the issue is most likely caused by the steering wheel's clock spring (airbag spiral cable). Fault Diagnosis: If the abnormal sound comes from inside the steering wheel, the issue is most likely caused by the steering wheel's clock spring. Remove the clock spring and apply some grease to see if the noise persists. If it still buzzes, replace the clock spring as it is already damaged. Be gentle when removing the steering wheel, or disconnect the airbag fuse to prevent the airbag from deploying. Steering Wheel Usage Tips: Avoid turning the steering wheel while the car is stationary; try to steer only after the vehicle is in motion. When the car is parked, return the steering wheel to the neutral position to prevent unnecessary load on the suspension system and tires. When making a U-turn, try to avoid turning the steering wheel to its maximum limit.

Do new energy electric vehicles require a driver's license?

New energy electric vehicles require a driver's license, and a Class C driver's license is mandatory for road use. The reasons are as follows: Electric vehicles are a general term for pure electric vehicles, hybrid vehicles, and fuel cell vehicles. The length, width, and speed of electric vehicles are the same as those of motor vehicles, with a maximum speed of 60 km/h. The vehicle performance far exceeds that of low-speed electric vehicles for the elderly, so electric vehicles are still classified as motor vehicles, and drivers must hold a Class C driver's license to drive on the road. The registration regulations are as follows: According to national regulations, electric vehicles must be registered. They must comply with the relevant provisions of the "Announcement of National Motor Vehicle Manufacturers and Products" issued by the Ministry of Industry and Information Technology, and possess a vehicle qualification certificate, purchase invoice, tax payment certificate, compulsory traffic insurance, etc. Vehicles not listed in the "Announcement of Road Motor Vehicle Manufacturers and Products" cannot be registered as required.

Will points be deducted for not using the turn signal when turning right?

Points will be deducted for not using the turn signal when turning right. Here is some extended information about using turn signals: 1. Turn on the left turn signal: When turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, you should turn on the left turn signal in advance. 2. Turn on the right turn signal: When turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside, you should turn on the right turn signal in advance. 3. Using turn signals: Not using the turn signal when turning is a violation of traffic rules. Therefore, motor vehicles must use turn signals when turning, overtaking, or changing lanes.

Should a new car be driven at high speeds and at what mileage should it start?

Avoid driving a new car at high speeds, but it can be done after about 5,000 kilometers. Reasons are as follows: During the break-in period of a new car, high-speed driving above 90 km/h should be avoided. When the new car has been driven for about 5,000 kilometers and is about to complete the break-in period, the owner can briefly run the engine above 4,000 RPM to reduce carbon buildup and improve engine performance. Other break-in considerations for new cars: A new car during the break-in period should avoid fully loaded driving because excessive load increases the burden on the engine and transmission, causing the engine to output excessive power and leading to excessive wear of components. Therefore, owners should be aware of their car's maximum load capacity and avoid fully loaded driving during the break-in period to extend the vehicle's lifespan. Owners should also avoid prolonged use of low gears and intentionally allow each gear to undergo the break-in process. For automatic transmission models, although the manual gear shifting break-in process is eliminated, owners should accelerate continuously under good road conditions to allow the transmission to shift up smoothly and avoid insufficient break-in of higher gears.
