Engine oil maintenance refers to the replacement of engine oil when a vehicle reaches a certain mileage. Engine oil is the lubricant used by the engine, composed of base oil and additives. It serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. Base oil is the primary component of lubricants, determining their fundamental properties. Additives compensate for and enhance the performance deficiencies of the base oil, providing certain new characteristics, making them an essential part of lubricants. Currently, there are three types of engine oils available in the market: conventional mineral oil, semi-synthetic oil, and full-synthetic oil.

Are Car Scratch Repair Tools Really Effective?

Car scratch repair tools can be somewhat useful. They can handle some minor scratches and are more cost-effective than car washing and waxing. Car scratch repair tools include: 1. Touch-up paint pen: A touch-up paint pen can cover some small and shallow scratches, making them less noticeable. Although there is still a certain gap compared to the original factory paint (color difference exists), and the durability is certainly not comparable to the original factory paint, after all, the touch-up paint pen is only for local touch-ups, the overall effect is relatively good. 2. Toothpaste: Because toothpaste itself has a grinding function, it is equivalent to applying a layer of wax to your car, and the repair effect is quite good. However, using toothpaste for repair can only address minor scratches; it has little effect on deeper scratches. 3. Car paint scratch repair agent: The car paint scratch repair agent works on the same principle as toothpaste, with a grinding effect that can quickly repair car paint scratches. Of course, this can only repair minor scratches.

What is the fuel consumption of the new Hongqi HS5?

The comprehensive fuel consumption of the new Hongqi HS5 is approximately 10.7 liters per 100 kilometers, which indicates relatively good fuel efficiency for this vehicle. The Hongqi HS5 is equipped with a 2.0-liter turbocharged engine across all variants, delivering a maximum power of 165 kW and a maximum torque of 340 Nm. Factors affecting fuel consumption are as follows: 1. Rough roads increase fuel consumption: Driving on congested or uneven roads for extended periods in lower gears will inevitably increase fuel consumption. 2. Overloading the trunk raises fuel consumption: Using the trunk as a storage space and filling it with unnecessary items increases the vehicle's weight. It's important to note that vehicle weight is directly proportional to fuel consumption. A 10% reduction in vehicle weight can lead to a corresponding percentage decrease in fuel consumption.
