What to Do with License Plates After Selling a Car?

After selling a car, there are two possible outcomes for the license plates, as follows: 1. The owner continues to use them: If the owner has used the license plates for more than 3 years, they have priority to continue using them. 2. Return to the public pool: If the owner has used the license plates for less than 3 years, the plates will be immediately returned to the public pool and re-enter the national license plate database for other car owners to freely choose from. Below are the reasons why license plates cannot be sold along with the car: National policy restrictions: Car license plates are not private property; they belong to the state. The owner only has the right to use the plates, not ownership. Due to this attribute of car license plates, owners cannot buy or sell them. However, the car itself is private property, and the owner can freely decide its use and destination.

Reasons for Abnormal Noise During Window Glass Movement

Reasons for abnormal noise during window glass movement include foreign objects in the rubber guide rails, etc. Below are the specific causes of abnormal noise during window glass movement: 1. Dirty rubber guide rails of the door glass: The rubber guide rails of the door glass easily accumulate dust, causing abnormal noise when the glass moves. In this case, you can first clean the dust from the rubber guide rails with water, dry the moisture, and then spray a little rubber protectant or lubricant on the rubber guide rails. The noise during glass movement will then disappear. 2. Aging rubber guide rails of the door glass: The rubber guide rails of the door glass are exposed to sun and rain all year round, making them prone to aging and losing elasticity. Friction between the glass and the aged rubber guide rails during movement will produce abnormal noise. This situation can only be resolved by replacing the rubber guide rails with new ones.

Can Different Brands of Gasoline Be Mixed?

Gasoline from different gas stations and brands can be mixed as long as they have the same octane rating. If the octane ratings differ, even if the gasoline is from the same brand, they should not be mixed. Mixing different octane fuels can lead to abnormal combustion, causing engine knocking. Knocking not only damages the combustion chamber but also directly affects the engine's normal operation and may even cause severe engine damage. To determine the appropriate gasoline grade for your vehicle, refer to the car's user manual or check the fuel grade marked on the fuel tank cap. What to do if you fill up with the wrong gasoline: If you use a higher octane gasoline than required (e.g., filling with 95 octane when 92 is specified), simply switch back to 92 octane after the current fuel is consumed. If you use a lower octane gasoline than required (e.g., filling with 92 octane when 95 is specified), you can add a high anti-knock fuel additive. Alternatively, you can drain the fuel and refill with the correct 95 octane gasoline.
