How to Identify the Authenticity of Motor Oil?

Methods to distinguish the authenticity of motor oil: 1. Check the packaging: Genuine motor oil usually has neat packaging, while counterfeit oil often has rough packaging with blurred fonts. Authentic oil also has a sealed tin foil at the oil opening, bearing the manufacturer's special mark. 2. Examine the oil's appearance: Genuine oil is light-colored, transparent, free of impurities, suspended particles, or sediment, and flows well when shaken. Additionally, genuine oil is much darker in color compared to counterfeit oil. 3. Smell the oil and feel its texture: Genuine oil has a mild smell, while counterfeit oil has a strong and pungent odor. At the same viscosity grade, genuine oil feels less viscous, whereas counterfeit oil feels stickier and may form threads when touched. 4. Consider the price: Genuine motor oil prices usually do not vary significantly, so oil with a price that is drastically different from others may be counterfeit.

Why does the front wheel squeak when the car is turning?

The reasons for the front wheel squeaking when the car is turning are as follows: 1. Severe wear: The front tires of the vehicle are significantly worn, and the owner needs to replace them. 2. Lack of lubrication: The steering gear is damaged or lacks lubrication, and the owner should apply some lubricating oil to the steering gear bearings. 3. Foreign object friction: There are foreign objects on the ground that cause friction with the tires when turning in place. Tire maintenance methods are as follows: 1. Reduce the use of the steering function: Owners should try to avoid turning the steering wheel when the vehicle is parked. This causes considerable wear to both the steering gear and tires. It is best to use the steering function while the vehicle is moving, as this minimizes tire wear. 2. Steering gear maintenance: Owners should service the vehicle's steering gear every 10,000 kilometers to prevent damage from excessive use. The most critical component of the steering gear is the bearing. When the vehicle leaves the factory, the bearing is coated with a large amount of grease, but this grease gradually wears away with use. Owners need to replenish it periodically.

Which has larger blind spots, SUVs or sedans?

SUVs have larger front blind spots compared to sedans, but smaller rear blind spots. Here are some expanded details: 1. Front of the vehicle: SUV models are taller than sedans, so the window line and hood of an SUV are also higher. If you connect and extend the SUV driver's line of sight with the hood, you'll find this line is longer than that of a sedan. If low obstacles appear in front of both a sedan and an SUV, the sedan driver would spot them more easily while the SUV driver might have more difficulty noticing them. 2. Rear of the vehicle: Due to their taller body, SUVs actually have smaller blind spots in some aspects - the rear blind spot is smaller than that of sedans. The rear windshield of SUVs is basically vertical in shape and has a larger surface area than sedans. Additionally, SUVs don't have the "third compartment" that sedans have, so rear visibility is significantly better in SUVs compared to sedans.
