Can you not see the stream/p*sser in the pic alone coming out the back of the engine?
Watch the vid then.
I don't know what you're talking about, but every major fogging oil spray literally tells you to remove the spark plugs and spray down cylinder with the extension. He/she is not doing anything wrong and is using like it's designed even if a step is being omitted, there's certainly nothing strange about spraying it down the cylinder.

What you're saying is misleading. It makes it sound like the goal of spraying it through the intake is to burn it, it's not. The goal of fogging is to preserve the intake system and the cylinders (and more components if used in a two-stroke system). You stop when it starts smoking because that lets you know that it has reached the end of the intake system (the combustion chamber), not because the burning aids in the fogging process in any way. Once you see smoke the intake might have protection but the cylinders have no additional protection because anything that went in was burned. That's why the manufacturers tell you the second step is to pull the plugs, then spray down the cylinders. This way both the intake and the cylinders are protected.
It
is just adding oil to the cylinders, that's one of the steps but you're dismissing the ease of application for reasons I'm not certain of. You're not seriously arguing that pouring oil into a cylinder like you were doing a wet compression test, is the same as spraying aerosolized fogging oil into a cylinder with an extension, are you?
In post 4, Max was wondering/inquiring how fogging an engine is done. In post 5 Danh explains what he thinks is the method according to what it allegedly says on his can. (I'd like to see that can)
The way Danh explains it is incorrect. There is a lot more too it, like you can see in the vid, than simply pumping a couple squirts into each cylinder. That is the very last step after you have completely fogged the engine causing it to stall, it is not the entire process.
Danh's post is full of errors, which I am surprised you did not pick up on? He mentions the engine should be cold, he mentions nothing of rotating the engine a few times after some is sprayed into the cylinders, etc, etc.
If Danh truly believes, by spraying a couple squirts into each cylinder is how you fog an engine, then he is a 100% wrong. Nothing is "fogging" at all by doing that way, nothing is coating the internal parts as there is absolutely no "fogging" going on anywhere.
Well, gosh. I'll plead to perhaps using the verb "fogging" incorrectly. And I'll also copy to not rotating the engine afterwards because space limitations make it darn difficult to do by hand and, even with th accelerator floored I'm reluctant to use the starter for fear of getting fuel into the combustion chamber.
Keep in mind I'm not trying to clean the engine, valves, intake manifold, combustion chamber, etc. I'm just trying to do a simple task in the interest of perhaps preventing corrosion. And this is typically an additional or alternative method according to the makers of of these (non-fogging) sprays.
So, rephrasing my question, is the not-fogging process I've used for a bunch of years of any value? Does anyone else do the same?
Gotta love this place...
