The Speed of Rust Formation in Engines: Understanding the Risks

As a racer, you likely take great care in maintaining your engine to keep it running smoothly. However, even with regular use and maintenance, engines can be susceptible to rust and corrosion, especially during long storage periods. But how fast can rust form in an engine, and what can you do to prevent it?


The speed of rust formation depends on several factors, including the type of metal used in the engine, the level of moisture present, and the environmental conditions in which the engine is stored. In general, engines made of iron and steel are more susceptible to rust than aluminum or stainless steel.


Moisture is the primary culprit when it comes to rust formation in engines. In humid climates, or when an engine is stored in a damp environment, rust can start to form within a matter of days or even hours. Even a small amount of moisture can cause rust to form, so it's important to keep your engine dry and protected.


Another factor that can contribute to rust formation is a lack of use. When an engine sits unused for an extended period of time, oil and other lubricants can drain away, leaving metal parts exposed to moisture and air. This can lead to the rapid formation of rust and corrosion, causing damage to the internal components of the engine.


So, what can you do to prevent rust from forming in your engine during storage? The best way to protect your engine from rust is to use fogging oil. Fogging oil creates a protective barrier on the internal surfaces of your engine, preventing moisture and air from coming into contact with metal parts and causing rust and corrosion.


In addition to using fogging oil, you can also take steps to protect your engine during storage, such as:

  • Keeping it in a dry and well-ventilated space
  • Covering it with a protective cover
  • Starting the engine regularly to circulate oil and prevent the buildup of contaminants


Rust can form quickly in an engine, especially during long storage periods. By understanding the risks and taking steps to protect your engine, you can preserve its integrity and keep it running smoothly for years to come.


Fogging your engine is one of the fastest, easiest, and cheapest ways to prevent rust and corrosion. Foggit is the top-of-the-line fogging oil built for high-performance engines. Developed by two industry leaders in drag racing, Foggit was created to prevent rust and corrosion from developing and keep engines running at their absolute best learn more at and keep your high-performance engine protected.
