Question: How to use After run oil

       Remove this ad - become a site supporter!
How do you put after run oil in 4 strokes? I have been taking out the plug, putting the piston on a down stroke, then squirting Fogging Oil in the plug hole, and turning the prop over a few times.
Is this the right way?????
Fogging Oil Is a rust preventaive oil for 2 and 4 stroke engines in a 10 oz.spray can.. This oil foams as its applied. Its sold at Home Depot in the USA for $2.95

Foam in your engine.....won't it leave a residue? Fogging Oil....hmmm.
Why not use After Run Oil...its only 3.59 here in Canada.......
I use Marvel Mystery Oil also for Boat engines...'specially for Winter Storage.
There is a nipple to one side of the front bearing.....I attach tubing and my oil bottle.....turn the prop several times and it sucks up the oil. I then plug the tubing. Remove plug and pour oil....lots.
But it's ok if you want to Fog Up your engine... :P

Bootlegr, I know that on Saito engines there is a nipple on the backplate where I usually install a piece of fuel line and run it down and out the cowel of my plane. This of course is a crankcase breather line. After you have burned out all the fuel on your last flight of the day, I use a syringe with whatever type after run you choose, and connect it to this line and just pump a small portion of oil directly into the crank case.

Just flip the prop through a few times in both directions with the throttle setting just a few clicks open and that should do it.

I use air-tool oil. It absorbs moisture. It was recommended to me for both 2 and 4 strokes by experienced modelers and machinists.

I squirt some in the carb and crank the engine over a few times. I have also put some in the glow plug hole, and some in at the muffler hole.
