Should Engine Oil Be Changed When It Turns Black?

Engine oil has a certain lifespan, limited by both time and mileage, and does not necessarily need to be changed just because it turns black. There are several methods to determine whether engine oil should be replaced: 1. Smell Test: Pull out the dipstick and smell it closely. If there is a strong sour or foul odor, it indicates the oil has deteriorated and should be changed. 2. Rub Test: Take out the old oil and rub it repeatedly between your thumb and forefinger. Good-quality oil will feel smooth, produce little grit, and cause no friction. If you feel impurities, poor viscosity, or even a rough texture, it should be replaced. 3. Color Test: Place a few drops of old oil on a clean white filter paper. After the oil seeps in, high-quality oil will leave no powder, feel dry and smooth to the touch, and show a clear yellow infiltration zone. If it appears dark brown or black with impurities, it should be changed. 4. Light Test: Hold the dipstick at a 45-degree angle under light to observe the oil droplets. If the droplets are clear with no visible grit, the oil is still good. If there is a lot of grit, it should be replaced.

What is the function of the OFF button in a car?

The OFF button in a car is used to turn off the vehicle stability control system. The vehicle stability control system is enabled by default. If you need to disable it, press and hold the OFF button. The function of the vehicle stability control system is to intervene when the vehicle is taking a high-speed turn and the front or rear wheels, which have driving and steering functions, start to slip. The ESP (Electronic Stability Program) will automatically brake other wheels and intervene with the engine management system to prevent skidding and loss of control. There are several situations where you might need to turn OFF the system: 1. When the vehicle is stuck in mud or sand during off-road driving. 2. When aggressive driving such as drifting is required. 3. When snow chains are installed on the vehicle.

How to Apply for Vehicle Inspection in Another Province?

Currently, the traffic management authorities have fully implemented cross-province inspection for small cars, trucks, and medium-sized buses. Applicants can directly inspect their vehicles and obtain the inspection certificate in provinces other than the vehicle's registration location without needing to go through the entrustment inspection procedure. However, large passenger buses and school buses cannot be inspected in another province and must return to the vehicle's registration location for inspection. Inspection time requirements: Small and micro non-operational passenger vehicles are exempt from inspection for the first 6 years. For vehicles older than 6 years but less than 10 years, inspection is required every two years; for vehicles older than 10 years but less than 15 years, annual inspection is required; for vehicles older than 15 years, inspection is required every 6 months. Operational passenger vehicles must be inspected annually within the first 5 years; after 5 years, inspection is required every 6 months. Trucks and large and medium-sized non-operational passenger vehicles must be inspected annually within the first 10 years; after 10 years, inspection is required every 6 months. Imported vehicles, like other vehicle types, can undergo regular inspection at any inspection station. Inspection precautions: Vehicles that fail inspection must be repaired within a specified time limit. If they still fail after the deadline, the vehicle management office will confiscate their license plates and prohibit further driving. Vehicles that do not undergo inspection without reason or fail inspection are not allowed to drive on roads or transfer ownership. Vehicles that meet scrapping conditions or exceed the prescribed service life will not be inspected, and their license plates will be revoked, their records deleted, and they will be scrapped.

How to Defog While Driving on Rainy Summer Days?

Here are the methods to defog on rainy summer days: 1. Use specialized defogging products: While polishing the glass, these products form a thin transparent protective film on the glass, effectively preventing the condensation of water vapor that leads to fogging. 2. Air conditioning cooling method: Utilize the dehumidification function of the air conditioning system to reduce air humidity and remove fog. In summer, especially when multiple people enter the car and the air conditioning is not turned on promptly, the high humidity from exhaled breath can quickly cause the windshield to fog up. In this case, turn on the air conditioning to blow cold air towards the windshield. Using the dehumidification function of the air conditioning, the fog on the windshield can be removed quickly.

Can hybrid vehicles get green license plates in Beijing?

Beijing plug-in hybrid vehicles can obtain green license plates. Hybrid vehicles are divided into plug-in hybrids and range-extended hybrids. Plug-in hybrids are considered new energy vehicles and can get green plates, along with certain national subsidies. Hybrid vehicles, also known as composite power vehicles, are equipped with more than one power source: storage batteries, fuel cells, solar cells, and generator sets of internal combustion locomotives. Currently, composite power vehicles generally refer to those with an internal combustion locomotive generator plus storage batteries. License plates, commonly known as car plates, are panels hung on the front and rear of a vehicle, usually made of aluminum, sheet iron, plastic, or paper, engraved with the vehicle's registration number, registration region, or other relevant information.

Can a Car with an Installed Rear Wing Pass the Annual Inspection?

Installing a rear wing on a car will not pass the annual inspection. During the annual vehicle inspection, authorities will check whether the vehicle has been modified, altered, or reconstructed, and whether the vehicle's registration certificate, license plate, and vehicle records match the actual condition of the car, including any changes. They will also verify if the necessary approval and modification procedures have been completed. After modifying a car, the owner must update the vehicle's registration certificate photo at the local traffic management office. Failure to do so may result in penalties from traffic police. Annual Inspection Procedure: First, after submitting the inspection application, the vehicle undergoes an online inspection. The car is driven into an automatic inspection area where emissions, speed, lights, side slip, and chassis are tested to ensure they meet standards. Only when all items pass can the vehicle proceed. Next is the exterior inspection, which verifies the accuracy of the vehicle's license plate, type, body color, engine number, VIN code, and frame number. The inspector then checks the body's exterior, including the bumper, engine compartment, rearview mirrors, lower mirrors, window glass, paint, engine operation status, and details such as the interior of passenger vehicles and wheels. Finally, the owner can obtain the inspection report and application form from the inspector. If all items pass, the owner can proceed to pay the inspection fee and collect the vehicle registration certificate and compliance label. If any items fail, the owner must repair the vehicle and undergo a re-inspection until all items pass before proceeding with the visa formalities.
