What kind of engine oil should be used for the Golf 1.4T?

Why is there excessive exhaust gas without burning engine oil?

Excessive exhaust gas without burning engine oil is most likely caused by excessive piston ring clearance, which produces waste gas. Valve stem seals do not cause this type of exhaust gas, and excessive valve guide clearance can also lead to this phenomenon, although such faults are rare. The main causes are still related to the piston and piston rings. The following are the reasons for the fault: 1. Wear of the engine piston rings: Severe wear of the engine piston rings and cylinder liners, piston top erosion or cylinder scoring. If the piston rings and cylinder liners are severely worn, or if there is piston top erosion or cylinder scoring, the seal between the piston rings and cylinder liners becomes loose. During the compression and expansion processes of the diesel engine, a large amount of compressed gas enters the crankcase through the tiny gaps between the piston rings and cylinder liners, leading to increased crankcase exhaust gas pressure. The main symptoms include severe exhaust gas from the breather, insufficient engine power, and possibly blue smoke. 2. Incorrect installation of engine piston rings: If the piston rings are installed incorrectly with all gaps aligned, even if the piston rings are not worn, a large amount of high-pressure gas during the compression and expansion processes will enter the crankcase, causing increased crankcase exhaust gas pressure.

Do I still need to display the 2021 vehicle inspection sticker?

In 2021, physical vehicle inspection stickers are no longer required to be displayed, but an electronic version of the inspection certificate must be provided. Detailed explanation: Since June 20, 2020, electronic vehicle inspection certificates have been implemented nationwide in China. The electronic inspection certificates are issued through the unified national internet traffic safety service platform, making the application, presentation, and use of vehicle inspection certificates more convenient. According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": 1. License plates must be displayed in designated positions: Vehicle license plates must be displayed at the designated positions on the front and rear of the vehicle, kept clear and intact. Heavy and medium-duty trucks and their trailers, tractors and their trailers must have enlarged license plate numbers painted on the rear of the body or carriage, with characters upright and clearly visible. 2. Labels must not affect safe driving: Vehicle inspection certificates and insurance labels should be affixed to the upper right corner of the front windshield. Any painting, labels, or body advertisements on the vehicle must not affect safe driving.

How Often Should Toyota Genuine 0w20 Engine Oil Be Changed?

Toyota Genuine 0w20 engine oil and the oil filter should be replaced every 12 months or after exceeding 10,000 km of driving. It is essential to regularly change the engine oil of motor vehicles to ensure the proper operation of the engine. Engine oil effectively protects the internal components of the engine and ensures its normal power output. Engine oil, also known as engine lubricant, serves multiple functions including lubrication and friction reduction, aiding in cooling and temperature reduction, sealing to prevent leaks, rust and corrosion prevention, as well as shock absorption. When the oil pan indicates a low oil level, it is crucial to promptly add the same type of oil. Avoid mixing different types of oil as this can degrade the oil's performance, reducing its ability to protect the engine and leading to severe wear of engine components. Under the following conditions, the engine oil and oil filter should be replaced every 5,000 km or every 6 months: Extreme road conditions: frequent driving on bumpy, muddy, or snow-melting roads. Regular driving on dusty roads, areas with low paving rates, or roads in dry and dusty environments. Extreme driving conditions: vehicles frequently carrying heavy loads or overloaded; vehicles experiencing prolonged idling and/or long-distance low-speed driving. Continuous high-speed driving (80% or more of the maximum speed) for over 2 hours.

Why Can't a Spare Tire Be Used as a Regular Tire?

Spare tires cannot be used as regular tires for the following reasons: spare tires have different friction coefficients, ground adhesion, and air pressure compared to other tires. Prolonged use can affect the vehicle's braking system, steering system, and suspension system, posing significant safety hazards. Additionally, since spare tires and original tires are manufactured at different times, their aging, hardening, lifespan, and deformation vary. Therefore, long-term use is unsafe. Spare tires should be replaced with original tires as soon as possible after emergency use. Moreover, regardless of their width, spare tires have specific production and usage requirements set by manufacturers. Since spare tires are not used regularly, they do not experience wear. Using a brand-new tire alongside heavily worn tires can create safety risks. Currently, there are three internationally recognized types of spare tires: the first type is identical to the regular tire, known as a full-size spare; the second is a non-full-size spare, commonly referred to as a narrow tire, usually smaller in size; the third is a folding spare tire, which is stored folded in the trunk and inflated when needed for emergency use. The difference in size between spare tires and regular tires is primarily for safety reasons. Since car tires inevitably wear over time, even if a spare tire is of normal size, the difference in wear between the spare and the other tires can create safety hazards. To discourage long-term use of spare tires, manufacturers intentionally make spare tires smaller to prompt drivers to replace them with regular tires promptly. Spare tires also require maintenance: Regular inspections are necessary because spare tires are rarely used and often overlooked. When needed, drivers may find the spare tire flat or cracked, leading to significant issues. Avoid oil contamination. Oil products should not be stored with spare tires, as rubber, the main component of tires, is highly susceptible to damage from oil exposure. Some externally mounted spare tires are exposed to harsh weather conditions, which may shorten their lifespan.

What is the fuel tank capacity of the BYD Tang DM-i?

The fuel tank capacity of the Tang New Energy - 2021 DM-i 52KM Luxury model is 53L. It is equipped with a 1.5L turbocharged engine and an Electronic Continuously Variable Transmission (ECVT). The drivetrain is front-engine, front-wheel drive. The front suspension is a MacPherson independent suspension, and the rear suspension is a multi-link independent suspension. In the same vehicle class, the fuel tank capacity of the Tank 300 - 2021 Off-Road Edition 2.0T Explorer is 80L. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the manufacturer is measured from the bottom of the tank to the safe fill level, and there is additional space from the safe fill level to the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount may exceed the calibrated capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, marked with 'E' (Empty) and 'F' (Full). When the needle is close to 'E,' it indicates low fuel, and when it is near 'F,' it means the tank is sufficiently filled.
