About Fogging Oil

by Naima Manal

Winterizing the engine of seasonal equipment or a vehicle extends the engine's life. Protecting the internal engine parts from rust and corrosion through lubrication is essential for storing engines throughout the colder months. Fogging oil is important to the process of preserving an engine for use in the next season, as it extends the life of the engine and reduces its maintenance and operating expenses. Fogging oil is easy to apply, and the results are worth the investment.


When seasonal vehicles and equipment are stored for the off-season, unprotected engine and motor parts become subject to the elements of nature, drastic temperature changes, and inclement weather. This non-usage subjects the parts to condensation and erosion. Fogging oil is designed to keep erosion at bay by providing a protective coating and long-lasting lubrication to the motor parts. It provides protection during the freezing months, when other forms of engine lubrication may freeze or cease being effective. Fogging oil also protects engines and motors from residual fuel during the storage months, which can decrease engine performance, increase year-round maintenance, cause starting difficulties, and decrease the overall life of the equipment.


Fogging oil is applied to the carburetor when it is runs out of fuel. The oil is heavily sprayed into the carburetor as the last fuel burns off, to give it a full coat of protection for winterization. It is also applied, in spray form, to the inner surfaces of the engine's cylinders, to provide an even coat of protection and thereby preventing cylinder damage. In gas engines, fogging oil is sprayed into the air intake as the engine is running, and in diesel engines, it is applied to the intake manifold. This is to ensure that the oil is evenly distributed to those hard-to-reach areas.


Fogging oil applications protect several engine part types. Available in spray form, fogging oil can easily be applied to the valve guides, pistons, intake parts, cylinders and rings of power equipment. Fogging oil is designed to protect two- and four-stroke recreational bikes and all-terrain vehicles, hand-held power tools, smaller engines as used in lawn mowers, farming and construction equipment.


Applying fogging oil to a stored engine or motorized equipment prevents moisture from reaching its metal surfaces, preventing rust and corrosion. Fogging oil also provides lubrication and extra protection to the moving parts of the engine to ensure its functionality in the next season. It is used on all types of motors and provides an easy start-up the next time the equipment is used. It usually does not contain harmful chemicals, such as chlorinated solvents and CFCs.


General motor oils provide protection during engine usage, when the engine parts are used frequently. When an engine has to sit for an extended period of time, motor oils are limited in their efficacy. Fogging oil was developed to provide protection when a motor is retired for the season. It preserves the integrity of the engine and sets the stage for another year of maximum usage.
