How to Identify Genuine Engine Oil?

There are many methods to identify genuine engine oil. The following is a detailed analysis and introduction: 1. Check the anti-counterfeiting code: Look at the anti-counterfeiting code on the barrel. The anti-counterfeiting code on genuine engine oil barrels is very clear. Fake engine oil may not have an anti-counterfeiting code, and even if it does, it is likely to be blurry and easy to rub off. 2. Check the oil cap: The outer edge of a genuine oil cap is usually neat and flat, and the sealing cap is a one-time cap. If the oil cap is rough and there is no "pull-tab" seal at the opening, but instead it can be directly twisted open, it is likely to be refilled oil. 3. Check the material and workmanship of the oil barrel: Genuine products have complete material and workmanship with clear printing, while counterfeit products often have burrs and feel uneven to the touch. 4. Smell the odor and feel the viscosity: Genuine oil has a light smell, with a slight fragrance like crystal wax; fake oil has a strong and irritating odor. For oils of the same viscosity grade, the viscosity feels low at room temperature, while inferior oil feels sticky and may exhibit a stringy phenomenon when touched by hand.

I'm totally qualified to speak on this – I got scammed last year! Fake engine oil packaging can be super convincing, but the devil's in the details: Genuine bottles have perfectly smooth serrated cap edges, while fakes feel jagged. When you twist open the cap, authentic ones have a one-time breakable sealing ring. Real oil has a faint burnt aroma, whereas adulterated versions either lack odor or smell suspiciously fragrant. Here's my freezer test trick – authentic oil maintains good low-temperature fluidity without solidifying, while fakes turn into lard paste within two hours. Pro tip: Always scratch off official anti-counterfeit labels and scan the QR code twice – even barcodes can be faked with high precision nowadays!

Last time I almost got scammed during maintenance, now I've become half an oil identification expert. The most straightforward method is to check the laser engraving on the barrel: genuine products have sharp character edges like knife cuts, while counterfeit ones have blurry laser engravings with rough edges. When shaking, genuine oil has uniform and small bubbles that dissipate within ten seconds, whereas fake oil has large bubbles like soda. Pouring the oil into a transparent cup, genuine oil appears clear with a slight blue tint, while fake oil looks turbid like gutter oil. Remember to ask the merchant for an electronic invoice - major brands now support online verification. Input both the invoice code and anti-counterfeit code for dual authentication to ensure peace of mind.

What Causes Slow Cooling in Car Air Conditioning?

Slow cooling in car air conditioning may be caused by insufficient refrigerant due to low levels. The detailed reasons are as follows: Insufficient refrigerant due to low levels: The primary cause of insufficient refrigerant is typically minor leaks in the system. If the refrigerant level in the air conditioning system is low, the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease. As a result, the refrigerant absorbs less heat during evaporation in the evaporator, leading to reduced cooling capacity. Moisture infiltration in the air conditioning refrigeration system: There is a component in the refrigeration system called the dryer (or receiver-drier), whose main function is to absorb moisture from the refrigerant to prevent excessive moisture from reducing cooling efficiency. However, when the desiccant in the dryer becomes saturated, it can no longer filter out moisture. As the refrigerant passes through the expansion valve's throttle orifice, the pressure and temperature drop, causing the moisture in the refrigerant to freeze in the small orifice. This can obstruct refrigerant flow, increase resistance, or even block it completely. Reduced heat dissipation capacity of the condenser: Due to varying working environments, the condenser located in front of the car engine may become covered with oil, dirt, or debris, reducing its heat dissipation capacity. Additionally, issues with the cooling fan, such as a loose drive belt, reduced fan speed, or high-speed fan problems, can also impair the condenser's heat dissipation. The solution is to clean the condenser surface with a soft brush and promptly address any fan malfunctions.

What to Do When the Car AC Keeps Turning Off Automatically?

Check if the timer switch option on the AC remote control is turned on. If so, please turn it off. Check if the remote control is in sleep mode, where it will automatically turn off when the temperature reaches the adjusted setting. Switch this mode back to normal mode. The issue might be due to poor contact between the pins and sockets of the AC pipeline. Try unplugging the AC switch and inserting it into other pins to see if it still turns off automatically.

How to turn off the rear wiper of the Tiguan L?

The switch for the rear wiper of the Tiguan L is located behind the steering wheel, which is the same as the front wiper switch. The front wiper works by moving up and down, while the rear wiper works by pushing forward and backward. There is an 'off' position on the switch, and placing it in this 'off' position will turn it off.

What to Do When Driving Through Water

When driving through a waterlogged section, first assess whether it's passable. Always check the water level marker before entering a tunnel. Do not enter blindly without checking the water level marker. Drive slowly at low speed; never speed through. High speed can easily cause water to splash into the engine or other components. Starting the car in a large area of standing water will directly cause water to flow into the engine, and even continuously enter the cylinders through the intake pipe, causing the cylinders to fail.

How to Perform Sheet Metal Work on Aluminum Car Bodies?

Use a flame torch to heat the car body, softening the aluminum alloy body to facilitate better pulling. Once the dented area is softened, pulling work can be performed, accompanied by hammering during the pulling process. After repairing the dented area, use a file and a grinder to smooth out the surface, ensuring it is even.
