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.

When considering buying a new car, the odometer reading is a key indicator. Typically, a new car should have less than 50 kilometers on it to be considered reasonable, as factory testing and transportation processes consume some mileage, such as 10-30 kilometers. I once saw a newly arrived car with only 8 kilometers on it, which is what a truly new car looks like. If the mileage exceeds 100 kilometers, I would worry whether it was used as a test drive or display car, which could lead to early wear or potential issues. Before buying, don't just look at the number; also check the engine and exterior for any damage. It's best to confirm the driving records with the dealer to ensure peace of mind. Low mileage on a new car not only represents freshness but also affects long-term performance and resale value. Keeping it under 30 kilometers is the safest choice.

From a manufacturing perspective, the low mileage range of new vehicles ensures they haven't been abused. Factory pre-delivery testing typically doesn't exceed 10 kilometers, and including transportation, accumulating up to 50 kilometers is considered normal for delivery. I've encountered some imported vehicles that may approach 100 kilometers, but dealers should provide explanations, such as transportation details. Excessively high mileage, say over 150 kilometers, might indicate the vehicle has been reused or has issues. When purchasing, always request an inspection report and evaluate it alongside the overall vehicle condition. During maintenance, low-mileage new vehicles have more durable components, reducing early repair costs – this is the core of professional advice.

As an experienced driver, I emphasize that new cars with over 70 kilometers on the odometer should raise safety concerns. Ideally, keep it under 30 kilometers, as higher mileage could result from testing or misuse, increasing potential future failure risks. Ensuring low odometer readings is the first step to guarantee driving reliability. If you notice unusually high mileage, promptly have a technician thoroughly inspect the electrical system and engine to avoid hidden defects.

When buying a new car, I negotiate mileage just like the price: under 50 kilometers is the gold standard, but if it exceeds 80 kilometers, the dealer should offer a discount or additional services as compensation. The key is a thorough inspection, such as checking for scratches on the paint. Some dealerships' inventory cars might show higher mileage, but as long as it's under 100 kilometers and properly explained, it's still reasonable—don't fixate on the number and miss out on a good car. Always ask the dealer about warranty details to ensure a fair deal.
