Applying undercoating to a car's chassis is not mandatory; it depends on the usage conditions. Car chassis undercoating: It is a high-tech adhesive rubber asphalt coating. It features non-toxicity, high coverage rate, and strong adhesion, and can be sprayed on exposed parts of the vehicle such as the chassis, wheel hubs, fuel tank, lower body panels, and trunk. Functions of undercoating: Rust and corrosion prevention: It can provide a certain degree of isolation against rainwater, mud, snow, de-icing agents, oil stains, and other impurities on the road that may cause rust and corrosion to the chassis. Undercoating can also mitigate the impact of stones and sand on the chassis. With a protective coating thickness of approximately 3mm, it can reduce the impact force of stones and sand kicked up from the road to some extent.

Can You Still Drive with Only 10% Oil Left?

You can still drive with only 10% oil left, but it is generally not recommended to continue driving as it can cause more damage to the car. Here is some relevant information about car engine oil: 1. Definition: Engine oil, also known as engine lubricant, serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. It is often referred to as the 'blood' of the car. 2. Precautions: When removing the oil pan screw, avoid using an adjustable wrench as it can easily strip the screw. Before draining the oil, loosening the oil cap in advance will allow the old oil to flow more smoothly. When tightening the oil pan screw, be mindful of the force applied—just tighten it sufficiently to avoid stripping the threads. Some oil pan screws come with copper washers to prevent leaks, which need to be replaced periodically, and the oil pan screws themselves should also be replaced regularly.
