How to Identify the Authenticity of Engine Oil?

There are four methods to distinguish genuine from fake engine oil: observing the appearance of the oil; analyzing the viscosity of the oil; judging by the sound of the engine; and smelling the oil. Specific methods for identifying genuine and fake engine oil: Determine the authenticity of the oil by its packaging. The methods and approaches that can be used are "one touch, two scans, three picks": One touch: Feel the packaging for raised striped flakes; Two scans: Use a mobile phone to scan and compare the color ratio, angle, and distribution of the striped flakes to see if they match; Three picks: Pick out the flakes to complete the genuine product identification. Alternatively, official verification via a verification code can be used. Analyze the viscosity of the oil. Good oil is relatively thin to a certain extent, and there are no granular substances when rubbed by hand, while inferior oil may contain some granules. After all, fake oil is basically refined from waste oil, so it differs from oil formed in one process. Judge by the sound of the engine. When fake oil is exposed to high temperatures, it can become sticky. The higher the engine temperature, the stickier the oil becomes, and in severe cases, the oil can burn and turn into sludge. The sound of an engine with genuine oil is relatively uniform, without any noise, whereas fake oil produces a more chaotic sound. Smell the oil. Genuine oil has a faint, pleasant fragrance. Generally, engine oil is composed of base oil and additives. Except for mineral oil on the market, other types of oil basically contain chemical additives, which are 0.6% aromatic hydrocarbons. The intensity of the smell varies depending on the oil. If the oil has a pungent smell, it can be judged as fake oil.

Can You Add New Engine Oil Without Draining the Old Oil?

It is not advisable to add new engine oil without completely draining the old oil. The different densities and compositions of old and new oil can damage the engine. If the old oil is not fully drained and new oil is added, the mixture of old and new oil will shorten the lifespan of the newly replaced oil and reduce its lubrication effectiveness. This will increase engine wear and consequently shorten the engine's service life. Significance: The engine is the heart of a car, containing many metal surfaces that rub against each other during operation. These components move at high speeds in harsh environments, with operating temperatures reaching 400°C to 600°C. Advanced technology can convert natural gas into crystal-clean fully synthetic base oil, which is then enhanced with proprietary power-cleaning technology to create lubricants with superior cleaning and protective properties. Precautions: Under such extreme conditions, only qualified lubricants can reduce wear on engine components and extend their service life. Engine oils on the market can be broadly categorized into mineral oils and synthetic oils based on their base oil (vegetable oils are not considered due to their scarcity).

Can I drive with a QR code on my driver's license?

You can drive with a QR code on your driver's license. Some cities have implemented electronic documents, and registered motor vehicle drivers can use the QR code for their driver's license and vehicle registration information to undergo roadside inspections, information verification, and handle certain on-site simplified traffic violation procedures. Check mirrors frequently while driving: When turning or changing lanes, you must use turn signals, slow down, and check the rearview mirror before turning. For left turns, mainly check the left rearview mirror; for right turns, mainly check the right rearview mirror. For both left and right turns, always check the interior rearview mirror. Don’t just focus on the front of the car while driving: When driving on a clear road, look straight ahead about 100 meters, not just at the immediate front of the car. Pay attention to clutch control: Generally, when decelerating above 40 km/h, you don’t need to press the clutch first; wait until the speed drops to around 20 km/h before pressing the clutch. Steering: Turn the steering wheel slowly for high-speed turns and quickly for low-speed turns.

What engine is used in the Volkswagen T-Roc?

The engine of the Volkswagen T-Roc is produced by FAW-Volkswagen Engine (Dalian) Co., Ltd., and is a domestically manufactured engine. The engine model of the Volkswagen T-Roc is EA211-DLS. The 1.2T version engine has a maximum output power of 85 kW and a maximum torque of 175 Nm, while the 1.4T version engine has a maximum output power of 96 kW and a maximum torque of 225 Nm. For daily maintenance of the Volkswagen T-Roc's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, which can cause various problems for the engine. To avoid failures, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and the oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

Is there a right turn waiting gesture?

There is a right turn waiting gesture. The gesture for waiting to make a right turn is when the traffic police officer extends their left arm forward with the palm facing forward, indicating that vehicles directly ahead should stop; then the officer turns their head to face the right, and their right arm and palm swing straight to the left front with the palm facing left, indicating to the vehicles that the officer is facing to make a right turn. Right turn signal: When making a right turn, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside, the right turn signal should be activated in advance. When exiting a roundabout, the right turn signal should be used to alert vehicles behind and oncoming vehicles. This is a clear stipulation in the new traffic regulations. Previously, many drivers would use the left turn signal when entering a roundabout. Left turn signal: When making a left turn, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, the left turn signal should be activated in advance; because entering a highway involves turning left, while exiting a highway involves turning right. Similarly, when entering a main road from a side road, the left turn signal should be used.

Do Non-Motor Vehicle Warning Penalties Need to Be Handled?

Non-motor vehicle warning penalties do not need to be handled. A warning is one of the types of administrative penalties and the lightest administrative penalty. It refers to the sanction and admonition imposed by administrative authorities for minor violations, and the penalized person should promptly correct and heed the warning. Traffic Police Station Violation Handling: Bring the vehicle registration certificate, driver's license, and ID card to the violation handling window at the traffic police station. Bank Handling: Take the violation notice issued by the traffic police to the designated bank to pay the fine. The fine must be paid using a bank card under the name of the vehicle owner. Online Vehicle Management Office Handling: Register and handle the violation on the local online vehicle management office website. Alipay Handling: More and more regions in China have implemented violation sharing and cross-region handling. Violators can first check whether cross-region violations can be handled using online banking payment services. If they can be handled, proceed directly.
