I've been reading about after run oil on the forum, but nobody has explained how to use it. Do you just run it through the engine like regular fuel or what?

I use after run after I clean an engine or before I plan to store it for a period of time.

What I do is take the glow plug out and the muffler off. I then put a couple of drops of after run down the carb throat, 3-5 drops down the glow plug hole and a couple of drops directly into the cylinder thru the exhaust port where the muffler has been removed. Then I just turn it a few times to give the oil a chance to work its way thru everything.

If you're going to store an engine for a while, its probably best to seal it up in a zip-lock type bag to keep air and moisture out of it.

After Run is just what its name says - use it after a run.

Hope this helps,

Thanks Crash, that answered my question quite nicely.

If I am going to store one for a while, I put a lot of oil in it. I fill the carb, then turn it over a few times, then do it agian. Then as crash said, put it in plastic bag sealed. Works well.

well axeman I've explained it three different times ,and will do it again since you asked.After each day of running the engine I disconn. or drain or clamp off the fuel to the carb.conn the igniter to the glow plug start the engine after it has ran all the fuel out then reconn the igniter and spend the engine over some more to make sure all the fuel is used up.If a 2s add dozen or more drops of afterrun through the carb,if a 4s then same through the vent nipple,turn the engine over ,you are coating the bearings,if storing for a long period of time ,then do the same also remove the glow plug and add oil there,couple of drops of oil doesn't do much ,you are trying to desplace the fuel and residue with oil to stop the rust and corrosion.

Terrell said what I was going to say. Make sure you run all your fuel out of your engine or you are just shooting yourself in the foot with the after run oil. It's amazing how long those engines run with fuel lines off.

I run the fuel out of my engines after every flying session and fill them with Marvel Mystery Oil.Just turn your engine over enough when you are ready to fly again to get it out.Helps to remove the glow plug,just watch out if you're useing a starter to turn it over,as it will go everwhere.

Same thing but i don fill it up..just 4-6 drops in the haed and a few in the carb for the front bering..Thas all....But first,make sure you have all the nitro ran out of it...

On four strokes, use lots of oil in the crankcase, at least a teaspoon full. A few drops are almost useless. Marvel Mystery oil is not the best choice, no water protection. Use any air tool oil, automatic transmission fluid or (most economical) Rislone in the yellow container which you can get at most Walmarts, Kmarts or auto parts stores. Once you have the oil in the crankcase (thru the crankcase vent), point the engine down and turn the prop over a few times to coat the front bearing with the oil and displace any nitro solvents and moisture there.
