What is the classification of automotive engine oil?

Automotive engine oil is classified into: 1. AB series: for gasoline and light-duty diesel engines; 2. C series: catalyst-compatible engine oil; 3. E series: heavy-duty diesel engine oil. The functions of engine oil are: 1. Cooling and temperature reduction; 2. Sealing and leak prevention; 3. Cleaning; 4. Shock absorption and buffering; 5. Lubrication to reduce wear; 6. Rust and corrosion prevention; 7. Component protection. Engine oil, also known as engine lubricant, is composed of base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of the base oil's performance.

Can I Take the Written Test for Driver's License Without an ID Card?

You can take the written test (Subject 1) without an ID card. If you lose your ID card before the test, you can apply for a temporary ID card. A temporary ID card has the same validity as a regular ID card. The admission ticket and other required documents will be provided by the driving school, which will distribute them on the test day. Electronic IDs are not accepted for the test. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the Subject 1 test allows two attempts. If you fail the first time, you can retake it for free. If you fail the second time, the test will be terminated, and you can only reschedule after ten days. The test is computer-based and lasts 45 minutes. The Subject 1 test covers: driver's license and motor vehicle management regulations; road traffic conditions and rules; traffic violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized buses and trucks; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Test precautions for Subject 1: Candidates must dress appropriately (no slippers), and electronic devices or bags are not allowed in the test room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the screen, and store personal belongings in lockers before entering the test room. At the identity verification station, you will be assigned a seat. Once seated, begin the test, ensuring the camera is aligned with you. Follow test discipline strictly. If you fail the first attempt, a retake is available the same day. If you fail again, you must pay to reschedule. After the test, queue to collect your score sheet and sign it—unsigned sheets are invalid. There is no limit to the number of times you can reschedule Subject 1. Each test allows one retake if failed. If you skip the retake or fail again, the test ends, and you must reschedule. In contrast, Subject 2 and Subject 3 allow only five attempts each, with rescheduling permitted after ten days. If you fail the Subject 3 safety and civilized driving knowledge test, your passed road driving skills test results remain valid. The driver's license test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 covers traffic safety laws, regulations, and related knowledge. Subject 2 is the field driving skills test. Subject 3 includes two parts: road driving skills and safety and civilized driving knowledge. The latter is often called "Subject 4," though this term is unofficial (not mentioned in the Ministry of Public Security's Order No. 123). The test duration is 45 minutes.

How to Remove the Armrest Box?

The method for removing the armrest box: 1. Open the armrest box and remove the internal screws, which requires a No. 10 screwdriver; 2. Pull the handbrake up and pry open the plastic cover on one side of the handbrake; 3. Remove the cigarette lighter cover; 4. Remove the fixing screws. There will be two fixing screws under the cigarette lighter cover, requiring a No. 10 screwdriver, and then the armrest box fixing clips can be removed; 5. Put the gear lever into N gear and lift it up, the gear lever will separate from the gear core, then use a plastic pry tool to remove the gear lever cover; 6. Remove the self-tapping screws of the armrest box. These two screws are under the gear lever cover. At this point, support the rear part and lift it up to remove the armrest box.

Will the fuel consumption of Corolla decrease after the break-in period?

The fuel consumption of Corolla will decrease after the break-in period. The break-in period is generally demarcated by the first maintenance service. The period before the first maintenance is considered the break-in period, and after the first maintenance, it is considered post-break-in. Before changing the oil, avoid aggressive driving as the oil may contain metal shavings and impurities, which can increase engine wear. The first 2000 kilometers during the break-in period are particularly crucial. Pay attention to speed and load, try to avoid full-load driving, and refrain from sudden acceleration and braking. The combined fuel consumption of Corolla ranges from 4.0-5.6L/100km. There are currently 12 models of Corolla available for sale. The E-CVT Pioneer version has a fuel consumption of 4L/100km. The E-CVT Elite and E-CVT Flagship versions consume 4.1L/100km. The CVT Pioneer version consumes 5.1L/100km. The CVT Elite, CVT Elite CARE, and SPORT versions consume 5.2L/100km. The Pioneer PLUS version consumes 5.5L/100km. The Elite PLUS, Flagship, Luxury, and Manual Pioneer versions consume 5.6L/100km. The above figures are NEDC combined fuel consumption, measured under the NEDC test procedure. Actual fuel consumption ranges from 4.0-10.5L/100km. Here are five tips to help reduce fuel consumption while driving: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Avoid stomping on the accelerator suddenly, as this can multiply fuel consumption. Light acceleration and braking, early braking: While driving, press the accelerator lightly to avoid sudden increases in engine RPM and prevent the car from shaking, thereby improving fuel efficiency. By anticipating road conditions and applying slow, even acceleration or braking, fuel economy can improve by up to 20%. Maintain proper tire pressure: Keep tire pressure at the manufacturer-recommended level. For every 2 PSI below the recommended value (approximately 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular maintenance or vehicle checks: Timely oil changes can reduce carbon buildup (carbon deposits can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even misfires). Regularly check and replace dirty air filters, clean or replace fuel injectors, spark plugs, and throttle bodies as per mileage recommendations. Keep windows closed while driving: Open windows increase wind resistance, which in turn increases the vehicle's resistance, requiring more power and thus higher fuel consumption. To summarize, the following techniques can help reduce fuel consumption while driving: Start in low gear, press the accelerator gently, maintain proper tire pressure, perform regular maintenance or vehicle checks, and keep windows closed while driving.

What Causes the Car to Jerk and Shudder During Acceleration?

The reasons why a car jerks and shudders during acceleration are: 1. Dirty throttle body; 2. Excessive carbon buildup in the fuel injectors; 3. Excessive carbon buildup in the intake manifold; 4. Engine malfunction; 5. Insufficient cylinder pressure; 6. Faulty half-shaft; 7. Malfunction in the fuel system; 8. Aging engine components; 9. Ignition system failure. The solutions to address the jerking and shuddering during acceleration are: 1. Replace filters: including oil filter, fuel filter, and air filter. Replacing these filters can improve filtration efficiency, reduce impurities, and ensure more complete combustion in the engine; 2. Clean carbon deposits: including spark plug carbon deposits, throttle body carbon deposits, and cylinder carbon deposits.

How to Change Your Car's Oil by Yourself?

The steps to change your car's oil by yourself are: 1. Start the vehicle's engine to warm it up; 2. Unscrew the oil drain bolt; 3. Remove the oil filter; 4. Apply new oil to the gasket of the new oil filter; 5. Pour new oil into the oil pan; 6. Check for leaks under the engine, inspect the oil dipstick, and start the engine for testing. The functions of engine oil are: 1. To reduce friction and high temperatures; 2. To cool down the engine; 3. To clean and remove contaminants; 4. To cushion and absorb shocks; 5. To prevent rust and corrosion. The reasons for changing your car's oil are: 1. To improve and enhance lubrication for the engine's moving parts; 2. To extend the engine's lifespan; 3.
