Default After run oil - for motors with Silicone Putty

Sorry if this has been asked a hundred times, but the search engine wasn't much help.....

What kind of after run oil have you guys been using on the motors that use silicone putty in the crank? I know anything with petroleum is out of the question.

I have been using the JP after run oil and it works great, but now I can't seem to get it anywhere (everyone is out of stock that I checked).

Maybe I'm being over careful, but when you find a modded .21 motor (or 2) that you like, you want to keep it healthy. Thanks in advance for the help

Greg

After a very long time of trying various after run oils i can confidently say that any 0w30/5w30 synthetic motor oil.Products like Petronas, Mobil1, Castrol Edge etc..... a pint is also better value for money.
havent had any issues after changing to it. Bearings seem to like it it and last a we bit longer and a noticeable difference is that engines dont rust over long periods like when using afterun oils.

regular prather After run works fine in all mine but it depends on what filler is used.

Not meaning to rub anyone up the wrong way but synthetic oils are generally Hygroscopic , not all but some .. The safest bet is to use castor oil , it is completely inert and will protect against moisture

For engines with the putty in the crank mineral oil is supposed to be the best. Petroleum oils break down the putty (from what I've read). I use Marvel Mystery for my engines but I don't have any with the putty crank. I would play it safe and use the Mineral Oil. Ted, what fuel do you use? If Byron's or Werks you don't need after run at all. Just run the fuel out of the engine as best as you can and the left over oil does a great job. I have an engine I have stored over two winters after this and it looks great inside. I'm running TQ fuel now and have been doing the same thing, we'll see how that turns out. lol

I use tranny fluid for a reg auto transmission in automobile. Just atf tans fluid from local auto shop. A quart is cheap. Not sure if this is petroleum based(to lazy to do D.D. on that), however ive always used it on all my model engines, planes, boats, cars. Same as say hobbico aftern run.

If you are talking about the aerosol version of this its a big NO...Even the owners manual state this, it is the aerosol propellant that effects the putty.

If you are using the bulk pack that you use in a triggerr pack than yes that s fair enough.

With general automotive oils that may be so but from use i have yet to experience any hassles using Synthetic motor oil in fact the bearings seem to be lasting longer on my .21 Black Magic and .12 engines.
Previously using after run i used to get rust spots on the crank and bearings used to feel scratchy after a few runs but since using the motor oil i havent experienced this problem and it hasnt effected the epoxy/silicone filled cranks on my .12 motors.
At the moment i am using Petronas Syntium 5w30 synthetic motor oil and its been used from Feb this year.Previously to the Petronas oil i was using Mobil1 5w30.
