Which of the following statements about fogging an engine is true?

Fogging an engine involves coating its internal parts with oil to create a protective barrier against moisture and corrosion. This process is particularly important for engines that will be stored for an extended period, as it helps prevent rust, which can occur due to humidity and changes in temperature. By using fogging oil, which contains additives designed to cling to metal surfaces, owners can ensure that the internal components remain lubricated and protected while not in use.

The importance of fogging is especially highlighted in situations where engines may be exposed to water and moisture, such as those found in marine applications or equipment that is not run regularly. This preservation technique not only safeguards the engine components but also makes it easier to start the engine when it is time to use it again since it helps maintain proper lubrication across critical parts.

Other statements fall short of accurately representing best practices in engine care and maintenance. For example, undertaking fogging when the engine is still warm can lead to ineffective oil spread, and, while everyone should correctly assess their maintenance needs, fogging can be especially beneficial even in seasons other than winter, as engines are often at risk from moisture year-round. Additionally, removing the spark plug is not a standard requirement in fogging; the oil can often be introduced into the
