Is Engine Oxidation Normal for a New Car?
2 Answers
Engine surface oxidation is a normal phenomenon. For imported cars, engine oxidation is common as vehicles are typically transported from overseas to China via sea freight. The air and seawater at sea contain high salt content, which inevitably adheres to the car during transportation, causing some corrosion and leading to engine oxidation. Here is more information about car engine oxidation: 1. The engine casing is usually made of cast iron or aluminum alloy, which undergoes slow oxidation when exposed to air. This oxidation has almost no impact on the engine's performance throughout its lifespan. 2. In fact, surface oxidation of the engine only forms an oxide film, which protects the engine. No special treatment is required; simply keeping the engine surface clean is sufficient. 3. To prevent engine oxidation, you can purchase high-quality antifreeze from the market.
A couple of days ago, someone asked me if oxidation on a new car's engine is normal, and I think it's quite common. The engine is a metal component, such as the exhaust pipe or valves, and when exposed to air and humidity, minor rust spots naturally appear over time. New cars are coated with anti-rust protection when they leave the factory, but oxidation can easily occur in humid areas or when parked in the rain. I've noticed similar conditions when inspecting my own car—it's part of normal aging and doesn't affect performance or longevity. The key is to distinguish the location: oxidation on external parts is fine, but if it's on internal components like the oil cylinder or bearings, there might be a quality issue. I recommend driving more to heat up the engine and evaporate moisture, regularly washing and waxing the car to protect the surface, and avoiding long-term parking in underground garages. In most cases, oxidation on a new car is a natural reaction of the material adapting to the environment, so there's no need to worry excessively, but staying vigilant is always a good idea.
