Methods to identify genuine and fake engine oil are: 1. Check the packaging appearance: Genuine engine oil packaging is very neat with no rough edges, the sealing cap is a one-time use lid, and the box color is bright; fake engine oil packaging is rough and the color is dull. 2. Smell the odor and feel the texture: Genuine engine oil has a light smell with a slight crystal wax fragrance; fake engine oil has a strong and irritating odor, and feels less viscous at room temperature. 3. Observe the appearance: Genuine engine oil is light in color, transparent, free of impurities and sediments, and flows well when shaken; fake engine oil is darker in color, has impurities and sediments, flows poorly when shaken, or feels stringy when touched. 4. Shake the oil container to see if the oil flows well; bubbles in fake engine oil disappear more slowly.

I just experienced this last month. I bought cheap engine oil online, and within a few days of use, the engine started making a buzzing noise. Later, after having someone check it, I found out it was counterfeit. To distinguish between genuine and fake engine oil, start with the packaging. Genuine products have clear anti-counterfeit labels and exquisite printing, while fakes may appear blurry or have spelling errors. You can also smell it—genuine oil has no irritating odor, while fakes often have strange or strong chemical smells. A simple viscosity test involves pouring some oil on your hand. Genuine oil has a moderate thickness and won’t be too thin, while fake oil flows quickly like water. Using a UV light, genuine oil packaging has special anti-counterfeit marks that glow, while fakes don’t. Always check the verification code—genuine bottles have a barcode, and scanning it with the official app is the most reliable method. From now on, I’ll only buy from authorized stores and never chase cheap deals again. Fake engine oil damages the engine and wastes money—so be very careful.

As someone who frequently deals with cars, I believe identifying genuine and fake engine oil requires hands-on practice. First, observe the color and transparency—real oil is clear and light yellow without sediment, while fake oil appears black or contains impurities. Shake the bottle gently; genuine oil flows smoothly without splashing, whereas fake oil spills like water. For a more professional approach, use a viscometer to test—the standard value is printed on the packaging, with genuine oil typically having a viscosity index above 150. Don’t overlook anti-counterfeiting features; bottle caps often have QR codes that can be scanned to verify authenticity on the official website. If you accidentally purchase fake oil, symptoms like increased engine noise and higher fuel consumption will appear—replace it immediately. During regular maintenance, ask your mechanic to inspect the oil quality; professional tools like UV lights work even better. Developing good habits helps avoid losses.

How Much Engine Oil in the Car is Considered Normal?

Generally, the engine oil level in a car is considered normal when it is between the upper limit (MAX) and the lower limit (MIN). The optimal oil level is slightly closer to the upper limit. If the oil level is below the lower limit (MIN), it is not normal and requires maintenance. Additionally, when checking the oil level, the dipstick should be fully inserted. Below is more related information: 1. Functions of Engine Oil: "Engine oil" is an essential lubricant for ensuring the normal operation of the engine. Its specific functions include lubricating metal components, reducing friction between parts, dissipating the immense heat generated during engine operation, cleaning fine metal particles produced by wear, as well as providing sealing, vibration damping, and rust prevention. However, when adding engine oil, it is important to ensure the amount is neither too much nor too little. The oil level should be between the "low" (MIN) and "full" (MAX) marks on the dipstick. An oil level that is too low can lead to insufficient oil pressure, while an excessive oil level can increase the working resistance of the crankshaft and connecting rods and accelerate the formation of carbon deposits in the combustion chamber. 2. Precautions: After changing the engine oil in a car, the oil level should generally be between the lower line (MIN) and the upper line (MAX) on the dipstick. It is advisable not to exceed the upper line. Overfilling can cause issues such as foaming due to the crankshaft's agitation, which may damage the engine. Staying below the upper line is safe. After starting the engine, the oil level should ideally be in the middle to upper range. Overfilling may lead to problems like sluggish engine performance and oil seal leakage.

Why Does the Fan Keep Running After the Car Is Turned Off?

Fan keeps running because the engine coolant temperature is too high. Here is some extended information about high engine coolant temperature: 1. Causes: There are several reasons that can cause the engine coolant temperature to rise excessively or even boil over, such as damaged electronic components in the cooling system (thermostat, cooling fan), poor radiator performance, or insufficient coolant. 2. Solutions: Check if the lack of antifreeze is causing the high engine temperature. Also, inspect the coolant circulation to see if it is obstructed. Additionally, components like the coolant temperature sensor, water pump, thermostat, and cooling fan could all contribute to high temperatures. It is recommended to visit a repair shop for maintenance.

How to adjust the valve clearance of the SFH C9 engine?

No need to remove the magneto cover. Insert a 17mm socket into the valve position, shine a light inside, and you will see a marking line. Adjust the valve clearance by aligning with this line. Remove the valve cover, then remove the cylinder head. You will see two screws. First, shake them slightly to feel the clearance, then adjust it to be slightly smaller.

Why Won't My Car Start When It's Fine?

There are several reasons why a vehicle may not start: a dead battery, possibly due to leaving headlights on for an extended period; expired battery life, often caused by installing xenon headlights, high-power audio systems, or DVD players; incorrect gear position - automatic transmission vehicles must be in P or N gear to start; not depressing the clutch - manual transmission vehicles won't start without clutch engagement; excessive carbon buildup in the engine can also prevent starting. Below is more relevant information: Precautions: Always pay attention to electrical usage in the vehicle. Remember to unplug external devices like car computers or displays when exiting the vehicle, and ensure all lights are turned off. Additionally, regularly monitor dashboard warning lights. If the battery warning light remains illuminated while driving, promptly visit a repair shop or 4S dealership to address the issue.
