Winterizing with antifreeze

[chpthril]

Fogging is a means of coating the cylinders with a storage oil during layup. For your engine, theres 2 basic ways to do this. Easy way: with the flame arrester off, spry down the throttle body for the last 30 seconds of the engine running before shutting it down for good. Hard way: pull each spark plug one by one and spry into each cylinder, replace the plug, rotate engine by hand and move on to the next plug.

With a specific oil or whatever your engine oil is?

Marine fogging or storage oil. Can be had in an aerosol.

Chpthril is correct, as usual. Fogging/Storage oil is sold in aerosol cans with those thin tubes, like WD-40. If you spray some on a visible surface you'll see that it foams up a lot.

I shoot it through the air intakes on carbed engines. But on fuel injected engines I remove all plugs, shoot 2-3 seconds' worth in each cylinder, turn the crankshaft by hand a few turns, and replace the plugs (a good time to inspect and regap the plugs too, kill two birds with one stone). This is because the air intake path of modern fuel injected engines is full of expensive sensors that expect air, not oily sticky meant-to-adhere-to-everything chemicals. And next spring your cylinders will burn out that storage oil, but your air intake path doesn't have fire in it and so that oil will just sit in there, attracting dust and other particulates onto everything. I prefer to keep the air intake path, and its expensive air sensors, very clean.

Just my $0.02, YMMV, etc.

Along with winterizing the engine I also mix 50/50 distilled water and vinegar. I spay the apolstery and all compartments with it. It will change the pH level and prevent mold from growing.
