Is engine oil changed during the first maintenance?

The first maintenance includes an engine oil change. It is recommended to use the standard original equipment manufacturer (OEM) oil as suggested by the manufacturer, as OEM oil is specifically designed to fully match the vehicle model. The selection of oil grade and precautions are as follows: Selection of oil grade: The oil grade essentially represents the oil's viscosity, which can be divided into low-temperature viscosity and high-temperature viscosity. Low-temperature viscosity affects the engine's starting ability in cold conditions, while high-temperature viscosity influences the protection of engine components during operation. The oil grade is demarcated by the letter 'W'; the number before 'W' indicates low-temperature viscosity, and the number after 'W' represents high-temperature viscosity. A smaller number before 'W' means better viscosity at low temperatures, enhancing the engine's cold-start capability. A larger number after 'W' indicates higher viscosity at 100 degrees Celsius, forming a thicker oil film on engine components. However, higher high-temperature viscosity is not always better, as it increases the movement resistance of engine parts. Choose based on actual conditions. Precautions for using engine oil: Engine oil and diesel cannot be used interchangeably. It goes without saying that they cannot substitute for each other due to their differing chemical and physical properties. Different fuels have different requirements for engines, and substituting one for the other would result in wear or damage to either the gasoline or diesel engine. Unless there is a special note indicating that both fuels can be used interchangeably, substituting one for the other will have minimal impact.

Is Frequent Car Washing Good?

No. The optimal frequency for car washing is 3 to 4 times per month. Firstly, non-corrosive dirt actually provides protection to the car's paint. The greatest damage to car paint comes from ultraviolet (UV) rays, and such dirt can effectively reduce UV damage. For general dust, using a feather duster or a soft-bristle mop is sufficient. Additionally, unless you use professional car cleaning agents, most detergents contain strong chemicals that are harmful to the car. Both acidic and alkaline cleaners have some corrosive effect on the paint, so it's best to choose a neutral cleaning agent. Frequent washing also increases the likelihood of water containing sand or debris, which can scratch the paint. Frequent car washing accelerates paint oxidation and damages the outermost layer. As washing frequency increases, the paint becomes thinner and eventually loses its luster. Moreover, if the car is washed too often and encounters bad weather, moisture may not evaporate completely, leading to dust accumulation in crevices or rubber seals, which can worsen their deterioration. Here are some car washing tips: Choose mild weather—neither too cold nor too hot. Overcast weather hinders the drying of residual water, while intense sunlight causes the metal panels and paint to expand. Washing the car under such conditions can lead to paint brittleness and cracking due to rapid temperature changes. Select a spacious and sheltered washing area. After washing, pay special attention to areas prone to dirt and water stains, such as the hood hinges, wiper bases, ends of window seals, trunk drainage channels, and antenna bases. Wipe these areas thoroughly to prevent rust.

Can Wheel Scratches Be Repaired?

Wheel scratches can be repaired. The methods and precautions for repair are as follows: Repair methods: Inspect the scratches. If the damage does not reach the inner side of the wheel, it can be simply repaired. Use paint thinner to clean around the scratches and remove dirt. For the deepest parts of the scratches where dirt is hard to remove, use a toothpick to clean them thoroughly. To avoid accidentally painting unrelated areas, carefully apply masking tape around the scratches. Prepare the brush tip and apply touch-up paint. After the paint dries, it will shrink slightly, so it's best to apply it slightly raised. After painting, it takes about a week for the paint to fully dry. Once dry, use waterproof paper soaked in soapy water to smooth the surface. After wiping with waterproof paper, use a compound to restore shine and then apply wax. Precautions: First, during the wheel repair process, pay attention to the safety of the tire to prevent a blowout during repair, which could cause harm and losses. Throughout the inspection and repair process, always use a tire pressure gauge to check the tire pressure—this is the first point to note in wheel repair. Secondly, another important precaution when repairing wheels is not to schedule the repair immediately after stopping the vehicle. At this time, the heat generated by tire friction has not yet dissipated, and the wheel may deform. If repairs are done immediately, it can cause stress and damage the wheel. Many car owners end up with major issues from minor problems simply due to negligence, leading to unnecessary future losses.

What to do when sonaroff is flashing?

sonaroff flashing indicates that the ultrasonic positioning system is turned off, which means all the vehicle's radars are deactivated. You can try restarting the vehicle to resolve this issue. This situation usually occurs due to poor contact in the reverse radar wiring. Taking the car to a repair shop to fix the wiring connection will solve the problem.
