What should be the mileage on a new car's odometer?

[MacMiles]

Under normal circumstances, the mileage on a new car's odometer should be below 30 kilometers. There are three key points for daily car cleaning: 1. Clean the air filter: A dirty air filter can severely hinder fresh air from entering the cylinder, leading to overly rich gas mixtures and excessive exhaust emissions. When cleaning, avoid using water or oil; instead, use the tapping method or blowing method. The tapping method involves gently tapping the end of the filter element to dislodge dust. 2. Clean the oil filter: A clogged oil filter can obstruct the flow of lubricating oil, causing poor engine lubrication. It should be cleaned or replaced regularly. Typically, it should be replaced every 8,000 km, or every 5,000 km in dry climates. 3. Clean the battery: For maintenance-free batteries, first clean the top of the battery, then clean the battery terminals to prevent oxide formation that could lead to poor contact.
