Should You Add New Car Protectant During the First Maintenance?
2 Answers
Adding protectant provides better protection for the engine, but it is not mandatory. The primary functions of protectants include anti-wear, lubrication, noise reduction, power enhancement, and fuel savings. With improved lubrication, wear and tear are minimized, enhancing the working conditions of metal components within the engine, leading to smoother operation, increased power output, and reduced fuel consumption. Below is relevant information: First Maintenance Process and Timing: Generally, the next maintenance schedule will be clearly indicated in the service manual by the 4S dealership, specifying either time or mileage—whichever comes first. During the warranty period, maintenance must be performed at a 4S dealership using vehicle-specific engine oil, oil filters, etc. Maintenance Items: Typically, maintenance at a 4S dealership should follow the manufacturer's guidelines, such as replacing gear oil during the second maintenance. Failure to adhere to these guidelines may void certain warranty claims. However, certain components like air filters and cabin air filters should be replaced based on specific conditions. Generally, cabin air filters, engine air filters, and fuel filters should be replaced every 8,000–10,000 kilometers, though this may vary depending on driving conditions.
I just bought my first car, and when I went to the dealership for the initial maintenance, the service advisor enthusiastically recommended adding a new car protectant, claiming it could protect the engine from wear. However, I checked the owner's manual beforehand, and it didn't mention anything about this. The engine of a new car has already been lubricated and tested before leaving the factory. Within the first few thousand kilometers, it's the break-in period, and adding a protectant might actually interfere with the oil's performance, reducing its lubrication effectiveness. A friend of mine spent over 200 yuan on it, only to find the engine noise got louder. Later, he realized it was a waste of money. The key points of the initial maintenance are changing the engine oil and oil filter, as well as checking the brakes and tire pressure—don't skip these essentials. Most of the extra add-ons are just ways for businesses to make more money. I think new car owners should keep it simple and stick to the official manual—it saves money and gives peace of mind, without falling for sales pitches.
