Welcome to this week’s edition of How to Thursdays. In recent posts we added a couple of posts on how to protect your car for the winter. We covered how to store your classic car for the winter and how to winterize your car. Today we will cover how fogging your engine will help protect it for the winter.
Fogging the engine as part of your winterizing plan is a great way to keep rust buildup from the inside of your engine compartment. The inside of an engine is bare, unprotected steel, and too much time unprotected will allow it to rust. Fogging oil is a lightweight oil that will gently coat the walls of the system while it sits unused. Using fogging oil is easy as long as the correct application method is used for the right engine type.
STA-BIL ® Fogging Oil
Protecting the internal engine parts of your classic car from corrosion and rust by using fogging oil is essential for storing engines throughout the winter.
STA-BIL ® Fogging Oil is a great way to protect your engine before you store your classic car for the winter.
STA-BIL ® Fogging Oil is great for:
* Coats internal engine components to prevent corrosion
* Displaces moisture from metal to protect engine
* Lubricates cylinders to prevent cylinder damage (scuffing) at start up
August DelMonaco wrote a great post on The Proper Use of Fogging Oils, that you will want to give a read before fogging your engine for the first time.
Fogging a Carbureted Engine
For cars with carburetors, fogging will take place at the air intake. Once winterizing is complete, run the engine with the air filter out of the carburetor. If the fogging oil is not already in a sprayable container, find a spray bottle to place the oil in and start your engine. While it is running, spray fogging oil into the air intake until you see cloudy exhaust coming out of the tailpipes. This means the whole system has been coated. Turn off the engine, replace the air filter and the job is done.
Fogging a Fuel-Injected Engine
Fuel injection changes the application by quite a bit. Fogging should be the very last thing that is done before putting the car away. Plan your winterizing tune-up, including oil and spark plug changes. Change the oil first, and make sure the car is warm (not hot) upon completion. When removing each spark plug to change them, spray fogging oil into the hole beneath each plug. Place a new spark plug in after the oil has been sprayed, and keep the car turned off. Your car will be protected until spring.
