Methods to identify genuine or fake engine oil: 1. Examine the packaging appearance. Genuine oil packaging has neat craftsmanship without rough edges, and the cap is a one-time seal. The packaging box color is bright. Fake oil packaging has rough workmanship and dull colors. 2. Observe the oil appearance. At room temperature, genuine oil is much darker in color than fake oil. 3. Smell the scent and feel the texture. Genuine oil has a mild smell, while fake oil has a strong, pungent odor. For oils of the same viscosity grade, genuine oil feels less viscous at room temperature, whereas inferior oil feels stickier, and fake oil may exhibit a stringy texture when touched. 4. Freezing test. Place a small amount of oil in a paper cup and freeze it at around -15°C for 48 hours. After freezing, genuine oil will show good low-temperature fluidity with no significant change in transparency or color. Fake oil will become slightly thicker and appear cloudy.

What are the differences between U-turn and turning around for cars?

Both U-turn and turning around refer to a car changing direction. More specifically, a "U-turn" means a vehicle or ship turning in the opposite direction, while "turning around" means reversing direction, both of which can be used in traffic contexts. Below are specific introductions to U-turn techniques: Priority in steering wheel adjustment: During a car's U-turn, "steering wheel adjustment" plays a crucial role in changing the car's direction and position. Therefore, beginners should always remember "adjust the steering wheel first, then stop" before each halt during a U-turn. Avoid forcing the steering wheel: When making a U-turn, never force the steering wheel (turn it to the extreme) before starting or after stopping, to prevent damage to the steering components, avoid increasing the steering wheel's free play, and unnecessary tire wear. Before each stop, the distances between the left and right wheels and the roadside are unequal. Therefore, when judging the stopping distance, the wheel closest to the roadside should be taken as the reference. In areas with obstacles or buildings, also pay attention to observing the front and rear bumpers and the height of the vehicle body. Using semi-engagement: When making a U-turn on a road with a side slope, you can also use the terrain and adopt the "semi-engagement" method to rock back and forth for the U-turn without frequent gear changes. Note that "semi-engagement" should not be used for a long time, especially not as a substitute for braking. When making a U-turn in hazardous areas such as cliffs, deep ditches, or obstacles, the front of the car should face the dangerous side for better observation. Additionally, after stopping facing the dangerous side, be extremely careful not to engage the wrong gear when starting again. On sloped roads, strictly follow the essentials of starting on a slope.

Can New Energy Vehicles Drive on Highways?

New energy vehicles can drive on highways. The condition for new energy vehicles to drive on highways is that they must be produced by legitimate manufacturers and have the necessary documentation. Precautions for driving new energy vehicles on highways: Electric vehicles must replenish their power in time to keep the battery in a reasonable state. Refer to the usual frequency of use and driving range to determine the charging time. During normal driving, if the battery indicator shows red and yellow lights, it is time to charge; if only the red light remains, stop driving and charge as soon as possible, as over-discharging will shorten the battery's lifespan. The charging time should not be too long, otherwise, it may lead to overcharging, causing the vehicle's battery to overheat. Overcharging, over-discharging, and insufficient charging will all shorten the battery's lifespan. Documents required for new energy vehicles to drive on highways: The new energy vehicle driven by the driver should be produced by a legitimate manufacturer and possess the motor vehicle registration certificate, qualification certificate, and other credentials issued by relevant national authorities such as the Quality Supervision Bureau. The vehicle should have a special license plate for new energy vehicles (a temporary license plate is also acceptable) and a motor vehicle driving license issued by the traffic management department. The maximum speed of the vehicle should meet the speed requirements for highway driving. Additionally, within the highways of our province, the driver must also hold a C2 or higher driver's license. Conditions for new energy vehicles to drive on highways: Relevant regulations generally include the following aspects: vehicles driving on highways must meet the basic conditions for road driving, meaning the vehicle must be a motor vehicle registered with the traffic management authorities of the public security department. If it is a temporary road vehicle, it should also obtain a temporary pass license plate. At the same time, the vehicle should display the motor vehicle license plate, place the inspection qualification mark and insurance mark, and carry the motor vehicle driving license.

Is It Okay to Buy a Car with Waterlogged Floor?

Yes, it is acceptable. Water reaching the floor level is not considered severe, but it is still recommended to take the car to a 4S dealership for further inspection. Below are the specific reasons and solutions: Reasons: The main concern when a car is waterlogged is damage to the engine and electrical systems. Generally, as long as the water level is below the air intake, it is safe. Different car models have varying heights for the engine air intake and different levels of electrification and lowest electrical component positions. In most cases, a water level slightly above the cabin floor is not a problem. Solutions: Notify the insurance company and request an on-site inspection by the insurance company's staff or an authorized third-party appraiser. However, in situations where there are numerous waterlogged car cases, the insurance company may not be able to respond promptly. In such cases, the car owner or policyholder can take photos of the waterlogged scene using a camera or phone as evidence for the claim. Before the tow truck arrives, disconnect the car battery immediately to prevent accidental startup during towing, which could worsen the damage. You can also request towing assistance from the insurance company.
