Anyone here use WD40 to fog their engines for the winter? A fellow boater claims its just as good if not better than regular fogging oil. |

Very bad recommendation. WD-40 will seep pass the rings and contaminate the engine oil. |

in a 4 stroke or two stroke,the amount that could get past the rings/valves would not change the viscosity of the oil enough to do any damage.on the other hand just change your oil before spring start up ,problem solved.
fogging oil is pefferred as it burs off better,than WD/40,{Water Displacement # 40} |

I love WD-40 - use it all the time. I usually have 5 or 6 cans in different areas of my shop. But never used it to fog an engine, and don't think it's a good idea. It's basically a solvent.
WD-40 main ingredients are reportedly as follows. Actual formula is a trade secret.
-50% Stoddard solvent - a paraffin-derived clear, transparent liquid which is a common organic solvent used in painting and decorating. Somewhat similar to kerosene.
-25% carbon dioxide – propellant.
-15% mineral oil - alkanes and cyclic paraffin
-10% inert ingredients.
Your call. Would like to hear opinions from others on this thread. Always willing to learn something new. |

I'd vote NO on the WD-40; YES on the fogging oil. The solvent issue WD mentioned is the big driver; what is left after it evaporates is really "thin" (low viscosity) and won't last several months. The only exception was if the fogging oil was forgotten and it would be a while before you could get back with it. |

I don't understand why this is even an issue.
Go buy a can of fog fluid and use it. Fuel injected & f/i four strokers be careful. It's not recommended to spray frog fluid into throttle bodies. Either run it on an aux. tank w/ fog fluid mixed with stabilizer or after your done shoot a bit into each plug hole then crank it around a couple of times. |

I prefer to start the engines every 2-3 weeks and let run up to operating temp. Coats all the bearings and cylinders with oil and if a problem crops up during the winter, its not a rush fix in the spring if discovered on the first flash up of a new boating season. |

I have a 53 yr. old. small 7.5 outboard, 1956 Elgin; was my Dad's and now mine. Each winter he used to "pickle" the cylinders with regular motor oil.
Clean the overall engine and outer casing; change the lower unit oil and store it in a fairly dry area in the basement. I have used the "pickle" method for years or use Storage Seal; works for me; and the "Elgin" keeps on ticking. |
