Motor Storage

What does everyone use to fog there engines with for winter storage?

[Tim Weber]

I don't fog them with anything. I just make sure all the fuel is out of carb, fuel tank etc.

If you tip over and you are not sure its' fully dried out, drench it with ATF fluid. The ATF fluid dispclaces the water.

Thanks Tim..

I have alcohol burners and run them on gasoline and petroleum oil to get the alcohol, caster oil and water out. And right now I have 2 new (to me) VRP's spending the winter in the corner of the den and a Konig and a MSR Kawasaki out in the heated shop. I don't fog them because they are full of nice Ace Hardware 2 cycle oil but I don't think fogging would hurt anything.

I sold a Konig to a guy in Germany and I filled it with OMC Fogging OIl.

Amsoil Fogging Oil

Mike,

AMSOIL Engine Fogging Oil (FOG) offers superior film retention, providing long-term protection against corrosion and dry starts, extending engine life and reducing operating expenses. Its aerosol spray formulation offers easy and clean applications, while reaching more components and offering complete distribution of the oil, something especially beneficial in applications with horizontal cylinder orientation, such as outboard motors. Consult equipment owners manual for application directions.

Fogging can't hurt......

But fogging came about to prolong engine life when they are stored outdoors in the elements. If yours are in a dry, heated space for the off-season you may not need to bother. We run all of ours on an 8:1 oil mix so they are kind of fogged all the time. Also if the engine is not going to come apart over the winter we turn each one over several times while they sit to stir up the oil a bit.

Marvel Mystery Oil

Mike,

I use a Marvel Mystery Oil fogging routine after every race weekend with my PRO stuff. I should have done this routine with my CSH Yamato motor, but instead I used a gummy fogger oil that left a bad residue in the carb one year. Maxima's Premium 2-stroke Racing Oil (I bought at motorcycle shops) seems to leave fewer season-end deposits than some of the other stock/mod oil options.

Fogging Process: Disconnect the fuel line to the carbs, take the spark plugs out, turn the motor over briskly while spraying MMO in the carb throats (throttle tied to full open), and watch for red mist coming out of the spark plug holes (warning - anybody standing in front of the spark plug holes gets a red splotched shirt - LOL.) Take the float bowl off after fogging application, clean and inspect it for contamination residue, and drain out any excess oil. Check the float bowl again before running the motor after storage. MMO seems to be good for the motor gaskets and helps reduce aluminum and steel corrosion.

I think Keller told me at Trout Creek he adds a little non-ethanol fuel and something else to his MMO sprayer (he also uses MMO to "pickle" his check valves while they are in storage containers.) I just apply the MMO full strength from the can and use a garden atomizer bottle to spray it into the carbs. Works great and coats the crankcase innards before the next race or season. Burns out clean on the first starting of the motor without the usual plume of blue fog behind the motor. This is a tip I learned from Lee Tietze a number of years ago.

Thanks Al, I dont know why I did not think of that but MMO was what we used to store our engines for our RC boats,,Should of know it would work for this application also..

Fogging = old school. Remove any airbox or impediment to the carbs - fire engine up at high idle - disconnect fuel line - squirt fogging oil in carb throats until the resulting fog (fogging, remember) clears the neighborhood of all mosquitoes and prompts a neighbor to dial 911 to report the "fire." No fear of running out of fuel, engine will run on fogging oil, so when the visibility drops to near zero (fogging, remember) cut the engine, allow to cool, remove plugs, squirt oil in cylinders, replace plugs finger tight, rope engine a few times, declare job done and crack open a brew.

Another Option

Test throughout the winter and you won't have to worry about storing them.

Interesting reading! Pavlicks advice is the best.... if you can do it.
According to Ed LeDuc (Merc School 1960) do not rotate the engine during the storage period period becacause it scrapes the oil off the cylinder walls!!!
Run yer eng on avgas if possible, other wise just use 87 octane with your oil mix.
Buy a can of Tohatsu fogging oil and spray it into the carb around 1500-1800 rpm or just pull the plugs and spray it in there - pull the engine over - put the plugs back in.

That would be a nice option but over here we would need an ice breaker to make a coarse
