Status: offline 		That's what it says (in BOLD with an !) on my bottle of 30% Morgan Fuel Cool Power glow fuel. Is there an interaction issue with AR oils or what? It says, "Morgan Fuel contains a Rust Inhibitor and an Anti-oxidant for resting engines." Is true for all Morgan Fuels?

Status: online 		I am going to start using automatic transmission fluid as I just changed both rear bearings in my evolution and my super tigre,the bearings were not worn out just rusty.

I had thought that by using castor I was safe but it turned out to be BS.

from now on its run em empty and an eyedroper full of atf down the carb,then spin it over with the starter

these motors were just bought this year!

I don't seem to have any trouble when I flush the crankcases with ATF Dexron. I have a case of the stuff setting around. My new automobiles use synthetics now and I don't have another use for it.

.....I would never use Cruel Power in any of my engines, for any reason.
I rather like my expensive little aero-model engines, and I treat them with the greatest care.

I've never had a rusty bearing in almost 40 years, and I used to live in the Harbor of
Los Angeles, where the salt air would ruin all metals exposed to the atmosphere. I think
my success was primarily due to using castor oil, and plugging off the exhaust to prevent
oil from dripping out all over the place in the home. I have never used ARO.

Think about this....the methanol in the fuel is hygroscopic. It draws the moisture from the air.
The moisture (water) is what causes the rust, this is not a secret. If you run the excess fuel
out of the engine with the fuel line disconnected, you will eliminate most of the problem right
there. No methanol....no drawing in the moisture.

If you close the carb you will seal off the front of the engine, and plugging the outlet
of the exhaust with a wad of paper towel seals the engine against air and moisture getting
into the engine.

No moisture....no rust. The third part of the equation is the castor that helps prevent rust.
I believe if you employ these three things, rusty bearing will be a thing of the past.

FBD.

My fuel has always had some castor oil in it. I have used a MMO+ATF brew since the 70's and never had a rusted bearing in engines that I have bought new. The only engines I have had to replace bearings in are the ones I bought used.

I dunno why they printed it in BOLD with an exclamation mark at the end like it is some kind of "Caution" or something... I don't see any place on their web page to ask a question. Interesting story there about an engine that was underwater for 10 years tho.

I think I will continue to use ARO until I get an answer to this question.

Ive been using CoolPower for a very long time now, and I yet to see a negative effect on any of my engines - 2 or 4 stroke. I never use ATF as well but I run all my engines almost every weekend for several times.
When ever I open up the back cover for conrod bushing & crank bearing inspection, Its always as shiny as a mirror, with no signs of wear & tear.

I use ATF only when I put an engine to sleep for more than 3 months. Then I fill the crank case with ATF and seal the whole engine off completely with a stretch film.

Status: online 		Like "liquid_TR" stated only when the engine is to be stored for several months do I use after run oil. Throughout the flying season (in spite of breaks) I use nothing what-so-ever.

I happen to like Wildcat 30/18 all synthetic------so far no sign of rust in any of the engines so treated.
Wildcat states that they have an anti corrosion ingredient ------based upon my experience, I believe them and feel it is quite effective.

No rust is no rust!

If they were not worn, not loose, and not making noise then there was no need to replace them. The shields on bearings will rust long before the bearings. They are also hot enough to bake the castor oil to a red brown stain which is often mistaken for rust.

Status: offline 		Whatever you use , use lots of it and circulate it with a starter. Thinning your after run oil with camp fuel makes it flush better and is less messy. The only time I need a starter is when Im flushing the engine at the end of the day.
