How many kilometers will the exhaust pipe of a new car turn black?
2 Answers
The exhaust pipe of a new car will turn black after driving 5,000 kilometers. The following are specific methods for exhaust pipe maintenance: 1. Waterproofing: When driving in the rain or going to a car wash, pay attention to preventing water from entering the muffler, which can cause rust and affect the use of the exhaust pipe. 2. Rust prevention: Remove the muffler, block the drain hole, add rust-proof oil to evenly enter the cylinder, and then reinstall the muffler. 3. Cleaning: The main substance discharged from the car's exhaust pipe is carbon deposits. The exhaust pipe is often exposed to the outside and is connected to the interior of the car. Dirt inside can affect normal use, so it is important to clean the exhaust pipe regularly.
I noticed that the exhaust pipe of my car turned a bit black after running just over a thousand kilometers, which is actually quite normal. It mainly depends on your driving habits and fuel quality. For example, I often drive short distances in the city, with frequent cold starts of the engine, leading to incomplete combustion and carbon buildup. If it's a China VI standard vehicle, the gasoline is evaporated to meet emission standards, making it easier for particulate matter to adhere to the exhaust pipe after combustion. I specifically asked the technicians at the 4S dealership, and they said it's very common for new cars to turn black within the first two thousand kilometers, so there's no need to worry too much as long as it doesn’t affect the performance. If you're particularly concerned, you can add some fuel additives or occasionally take the car for a high-speed run to ensure more complete combustion in the engine.
