C2 and C3 are designations for the testing and certification standards of automotive lubricants established by the European automotive manufacturing industry. In terms of grade, C3 is higher than C2, but it is sufficient as long as it meets the requirements of your vehicle's engine. C2 and C3 engine oils are known for their stable quality and long-lasting performance. Here are the detailed descriptions: 1. C2: C2 can be used in high-performance gasoline and light-duty diesel engines equipped with DPF and TWC. It is a low-friction, low-viscosity oil. The minimum high-temperature high-shear viscosity for C2 is 2.9 mPa.s. This oil can extend the lifespan of DPF and TWC and maintain the vehicle's fuel economy. 2. C3: Similarly, C3 engine oil can also be used in high-performance gasoline and light-duty diesel engines equipped with DPF and TWC. The minimum high-temperature high-shear viscosity for C3 is 3.5 mPa.s, which is higher than that of C2, and it can further prolong the service life of DPF and TWC.

How Long Before New Drivers Can Drive on Highways?

New drivers can drive on highways as soon as they obtain their driver's license, but they must be accompanied by an experienced driver with more than three years of driving experience. Without such accompaniment, they must wait until they have held their license for at least one year. The first 12 months after a motor vehicle driver initially obtains their license is considered the probationary period. During this probationary period, a uniform-style probationary sign must be displayed or hung at the rear of the vehicle. The restrictions for driving during the probationary period are as follows: 1. Probationary drivers are not allowed to drive buses, commercial passenger vehicles, police cars, fire trucks, ambulances, engineering rescue vehicles, or vehicles carrying explosives, flammable and explosive chemicals, highly toxic substances, radioactive materials, or other hazardous materials; nor are they allowed to tow trailers. 2. When probationary drivers drive on highways, they must be accompanied by a driver who has held a driving license for the same or a higher vehicle category for more than three years. For drivers of small automatic transmission vehicles designed for disabled individuals, the accompanying driver must hold a license for small automatic transmission passenger vehicles or higher. 3. During the probationary period after adding a new vehicle category to their license, drivers are not subject to the above restrictions when driving vehicles within their original license category.

What Causes Volkswagen Engines to Burn Oil?

Volkswagen engines burn oil for the following reasons: 1. The fuel quality is poor, which easily leads to a large amount of carbon deposits forming in the combustion chamber. These deposits accelerate the wear between the piston and cylinder wall, causing excessive clearance and allowing oil to flow into the combustion chamber. 2. The valve seals and front/rear crankshaft seals age, leading to poor sealing and oil leakage. 3. The air filter and oil filter become clogged. If the air filter is blocked, airflow is restricted, pressure drops, and oil is sucked into the combustion chamber. 4. The throttle valve is dirty. There are many complex reasons why an engine burns oil, but this doesn't mean the engine has an 'incurable disease.' Many auto repair shops can fix this issue, provided the problem is addressed promptly. If the oil burning persists for a long time without repair, a major engine overhaul may be necessary.

Can Auto Hold and Engine Start-Stop Be Used Simultaneously?

Auto Start-Stop is used for stopping and starting the engine, while Auto Hold is used for stabilizing the vehicle after stopping. These are two completely different functions that can be used together. More details are as follows: 1. Engine Auto Start-Stop: The engine automatically shuts off when the vehicle comes to a temporary stop during driving and restarts automatically when it's time to move forward. 2. How the Auto Start-Stop System Works: When the driver stops the vehicle by pressing the brake pedal and shifting to neutral, the Start/Stop system automatically detects that the engine is idling and in neutral. The wheel speed sensor of the locking system shows zero, and the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine shuts off automatically. When the driver releases the brake or turns the steering wheel, the engine restarts automatically. 3. Auto Hold: This is an automatic braking function. When activated, it automatically applies the handbrake for the driver at traffic lights to prevent the vehicle from rolling backward. 4. How It Works: It integrates temporary braking during driving with long-term braking after stopping, using electronic control to achieve parking brake technology. Note: These are two distinct functions. Some drivers may confuse them, such as pressing the Auto Start-Stop button when intending to use Auto Hold, leading to forgetting to apply the handbrake and causing the vehicle to roll.

Why Are Top Supercars Mostly Manual Transmission?

Top supercars predominantly feature manual transmissions for the following reasons: 1. Advantages: Manual transmission vehicles are equipped with a clutch, unlike automatic transmission vehicles. This seemingly minor clutch component often plays a decisive role in driver safety. Statistics show that in accidents caused by mistakenly pressing the accelerator instead of the brake, the vast majority involve automatic transmission vehicles. Therefore, in terms of driving safety, manual transmission vehicles significantly outperform their automatic counterparts. 2. Principle: Due to the limited torque conversion range of hydraulic torque converters in automatic transmissions, multiple planetary gear sets are connected in series behind the turbine to enhance efficiency. The hydraulic control system automatically adjusts these planetary gears according to engine operating conditions, thereby achieving automatic torque conversion and gear shifting.

What is a Hatchback Car?

A hatchback car integrates the trunk and the cabin into one unit, resulting in only two compartments: the engine and the cabin. Below is a brief introduction to hatchback cars: 1. Hatchback primarily describes the body and model of the car. Typically, the engine compartment is one compartment, the trunk is another, and the cabin is a separate compartment. A hatchback combines the trunk and the cabin into a single unit, leaving only the engine and the cabin as the two compartments. 2. Hatchback models have a more standard appearance and offer good frontal collision protection performance. There is nothing inherently disadvantageous about this model, although the space might be slightly smaller. However, for daily commuting, it poses no issues at all.

How to Solve Oxygen Sensor Failure?

Oxygen sensor failure solutions are as follows: 1. Replace the oxygen sensor at an authorized 4S shop. Some car owners may opt for cheaper roadside repairs, but after replacement, be sure to use a diagnostic tool to check again when the engine is warm (oxygen sensors operate at high temperatures). A fluctuating signal output indicates a genuine part. 2. Since the oxygen sensor may not function when the vehicle is not operating, even if a counterfeit is installed, it won't be detectable on the dashboard. Therefore, it's advisable to choose authorized manufacturer shops for repairs and replacements. Symptoms of a faulty oxygen sensor are as follows: 1. Oxygen sensor failure can cause unstable idling and excessive fuel consumption. A damaged oxygen sensor significantly reduces engine power, causes sluggish acceleration, and results in black smoke from the exhaust pipe. 2. Oxygen sensor failure typically triggers the engine warning light, causes unstable idling, produces a sputtering sound from the exhaust, emits a pungent odor, and increases fuel consumption. You can use a diagnostic tool to check the voltage, which usually fluctuates between 0.1-1 volts, changing more than 8 times in 10 seconds. If the voltage fluctuates between 0.1-0.5 volts, it indicates a lean fuel mixture. If it fluctuates between 0.5-1 volts, it indicates a rich fuel mixture. If it remains steady between 0.4-0.5 volts, it means the oxygen sensor is damaged.
