I store a lot of used engines. Most will get stiff after a while of storage. I believe after run oil would help. I would like to know if bench running with a no nitro fuel with no castor and only synthetic oil prior to storage would help?

Personally, I don't think it matters. What you put in the engine as an after-run or storage oil is probably more important. I have been using straight automatic transmission fluid (Dexron type, don't know if it matters) for 20 years with excellent results. I use it as after run oil, assembly oil, and storage oil. 3 in 1 oil, WD40, and many other lubricants seem to gum up over time, but not transmission fluid. Other people use Marvel air tool oil, but transmission fluid is cheap and readily available. I'm sure other things will also work, but ATF has served me well.

That's not a good idea. No castor and only synthetic is likely to result in corrosion. Air tool oil, or synthetic motor oil - I use Mobil 1 0W40.

I have never used after run oil. allways use my own fuel. Just burn all the fuel out of the engine before putting it a way. I hear of all the problems people have, but I have never had one. I have never had a bearing go out. I just ran a engine from the 80's that had not been ran in 20 years. It has had 50 gal of fuel or more thru it and it is good as the day that I first ran it. There are allways stiff at first put a little fuel in it and let it set for a hour. Pour out the fuel and start it up.

I'd use the Marvel Mystery Air Tool Oil, Rislone, or ATF and put them in ziplock bags...maybe doubled, for salt air areas like Garf's. That's a big part of the problem...weather, and if you store them in a good dry part of the house, or out in the shed. ~> Steve
