Driving in the rain can easily wet the car chassis. Here is relevant information: Prone to rust: Rainwater causes more severe damage to the chassis. The chassis, being close to the ground, is particularly susceptible to rust during rainy days, so it's essential to pay attention to the cleaning and rust-proof treatment of the car chassis. Additionally, avoid using alkaline cleaning agents to wash the body and chassis. If the vehicle hasn't undergone chassis sealing, it's advisable to apply a chassis sealant. When water is deep: During heavy rain or when crossing deep water, the exhaust pipe can easily take in water, leading to serious consequences like engine water ingress. Therefore, it's crucial to assess the water depth and determine if it's safe to proceed, ensuring familiarity with the terrain and that the water depth does not exceed 30~50cm.

When driving in the rain, the chassis is bound to get wet because rainwater splashes up from the road. The chassis is the metal component at the bottom of the car, exposed without much cover. Especially when passing through waterlogged areas, splashing water can wet the chassis, including the suspension and exhaust pipe. This may lead to rust issues, and over time, the parts can corrode. I recommend checking the chassis for accumulated water or mud after each rain before parking. Most modern cars have anti-rust coatings for protection, but older models may need regular rust-proofing sprays. To avoid long-term damage, I try to avoid deep puddles and reduce speed to minimize splashing on rainy days. Daily maintenance is also crucial—rinsing the chassis during car washes helps prevent rust.

How often should the gear oil of a scooter be changed?

The replacement cycle for scooter gear oil is between 6000 to 10000 kilometers. Unlike engine oil, gear oil does not require frequent changes. Here are the daily maintenance methods for motorcycles: 1. During the break-in period, keep the motorcycle idle speed at 100 RPM. 2. Match the motorcycle gear with the corresponding speed. 3. When you need to brake due to an upcoming situation, release the throttle, step on the rear brake with your right foot, and gently apply the front brake with your right hand. 4. Regularly inspect the spark plugs. 5. When installing a new spark plug, hand-tighten it until it doesn't move, then use a spark plug socket to tighten it an additional quarter to half a turn. 6.
