I use mystery oil also ..Occassionaly get a fouled plug or two but for the most part no!
I fog my two stroke outboards as well and those are usually ok in the spring but I usually change em out anyway since its a 2 smoke.
But to change em all every spring just in case is a waste IMHO

I use ATF or "Fogging Oil" but not the stuff that's in the spray can.

Me too, never had a plug foul in the 10 years I have been using it. I will also fog if I know the boat will sit for a couple weeks in the summer.

Mercury Marine Fogging Oil is my personal favorite as the chemistry is designed to displace moisture very well.

The whole idea of fogging is that it helps protect against rust and corrosion during seasonal storage periods. Helps protect metal surfaces (cylinder walls, pistons, rings, valve guides, and intake system components) against moisture and humidity. Displaces water to help prevent damage from moisture accumulation.

Usually 2 ounces is all you would ever use and fouling should be minimal. Often times too much is used and then fouling is a big concern..


I am not one to use ATF for fogging...and would say to stick with a MARINE SPECIFIC fogging oil.
Here is what is in ATF fluid...

ATF typically contains the following components:
Dispersants
Sludge & varnish control
Antioxidants
Prohibit oxidation
Antiwear
Planetary gear, bushing, thrust washer protection
Friction modifier
Modify clutch plate and band friction
Corrosion inhibitor
Prevent corrosion and rust
Seal swell agent
Prevent loss of fluid via seals
Viscosity Improver
Reduce rate of change of viscosity

CRC makes fogging oil that comes in 5 gallon pails. It smells like Caramel, that's the good stuff..

Personally, I don't like the Aerosol cans. If you're doing anti-freeze and fogging oil at the same time it's a b#TCH.

I know that this question has been asked many times before...but I've never seen an answer. Do you own a boat and, if so, what kind?
