An engine oil temperature of 100 degrees is normal, as the operating temperature of engine oil typically ranges between 70 to 90 degrees. Below is relevant information about car engine oil: Functions of engine oil: Reduces friction and high temperatures, minimizes gas leakage, prevents contamination from external pollutants, shields components from water, air, acidic harmful gases, cushions the pressure rise in engine cylinder ports, and cleans dirt generated on component surfaces. Introduction to engine oil: Engine oil, also known as engine lubricant, serves multiple purposes including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and enhance the base oil's performance shortcomings, imparting new characteristics and forming an essential part of the lubricant.

What to Do If the Car Hasn't Been Transferred and the Buyer Can't Be Contacted?

If the car has been sold but the ownership hasn't been transferred and the buyer can't be found, you can apply to the traffic police department to have the vehicle suspended. Once the owner drives the car out, the traffic police department will detain it. At this point, the new owner will have to contact you, and then you can request the transfer of ownership. When applying, you need to bring your ID card and the vehicle's registration documents.

Will driving a new car in the rain damage it?

As long as you clean it promptly, driving a new car in the rain will not damage it. Here are some precautions for driving in the rain: 1. Slow down: Regardless of the road width or surface conditions, drive slowly in the rain and always pay attention to the distance between vehicles ahead and behind, preparing mentally for various emergency measures. Visibility is low in the rain, and the field of vision is poor. The braking distance and other emergency performance of the vehicle will also be reduced, so slow down in advance to leave enough time and space to handle situations and ensure safety. 2. Maintain distance: When driving in the rain with obstructed vision, pay attention to maintaining distance between vehicles, always observe the distance between vehicles ahead and behind, and increase the safety distance. Stay especially far away from large vehicles: first, they can block your view; second, puddles that large vehicles can pass through may not be passable for small cars, and large vehicles can easily splash water waves, interfering with the driving of small cars.

Why Don't 4S Shops Use Filler-Free Repair?

4S shops do perform filler-free (dentless) repairs, but they are relatively rare. This is because the dentless repair technology is not yet mature, resulting in fewer opportunities for its application. Many vehicles brought in for repairs have body damage that cannot be effectively addressed with dentless repair, so 4S shops tend to stick with the more traditional sheet metal and paint repair methods for reliability. Dentless repair, also known as micro-dent repair, is a technique that restores body dents without the need for repainting or applying filler. Due to its simplicity and significantly higher efficiency compared to conventional body repair methods, dentless repair was initially used mainly for fixing hail damage on cars. However, with technological advancements, larger dents can now be repaired using this method, making it a reliable option as long as the car's paint remains intact. Dentless repair primarily relies on external force to restore dents to their original shape, with two main approaches: the pull-out method and the push-up method.

Golf 7 Fuel Tank Cover Malfunction?

Golf 7 fuel tank cover malfunction may be caused by the spring plate issue, usually due to prolonged use leading to insufficient elasticity of the spring plate. In northern regions, it could also be due to freezing. It's rarely caused by a broken cable. You can try having one person pull the switch in the driver's compartment while another pulls the fuel tank cover from the outside to see if it can be opened. Below is additional information: Reasons why the fuel tank cover won't close: Sometimes improper installation of the fuel tank cover may cause the outer cover to fail to close. The usual operation when refueling is to lift the fuel tank switch, which is located on the left rear side of the vehicle, to open the fuel tank cover, then slowly unscrew the fuel tank cap and hang it on the back of the fuel filler cap. When reinstalling the fuel tank cap, turn it until you hear a click, and the cap will slightly rotate back when released.
