No sir, don't make that conclusion for me please
I have ran my engines on both coolpower and omega and they all run better with omega and I am not afraid of a lean run and I'm not saying syn oil is bad they just run better
I don't really care why they run better, I have mich more important thing to waste brain cells on
I just know it works for me and to each his own having tried both I'll stick with some castor

I had trouble getting Bakers AA to mix with camp fuel, a little BP2380 (which is 99% ester) cleared it up. Maxima 927 MSDS claims castor and ester as its main componets, it also mixes very well with all common fuels.

Castor bean plants are toxic to many workers who harvest them. This doesn't stop third world countries from producing it however, as castor oil is valuable.



Castor bean plants are sometimes grown in this country as ornamentals. When I was a child my mother had a few plants in the backyard. The plants would die back in the fall and I would cut the stalks back. It was great fun to use a machete and pretend I was fighting pirates.
Now that I know how deadly they are I realize that perhaps I actually did save the world!

This would be post #600 I think.

Sooooooooooooooo, what have you guys decided the "final word" is?
Q.


Actually that was post 600 of one of many similar threads.
One conclusion that has become obvious to me is that for a hobby some people take their oil, and often themselves, waaay to seriously.

I really don't know if castor is needed with the new synthetics & engines out now, but was advised by some pretty smart guys that my old engines needed some castor in the fuel. Since that is what was available back then when the engines were designed.

There is some castor in the fuel (power master) that I'm using now, but don't know how much. Really doesn't matter to me anyway as I don't mix my own fuel.

What I'm getting from all this is that a little castor can't hurt, even if it's really not needed with the newer engines, and synthetics available now........But I knew that 600+ posts ago! Oh-well!

I'm not buying into the new engine materials theory. Pistons, rings, liners and
ball bearings haven't changed at all. The clearances are better, but that's all.

Status: offline 		As an addendum to my post on the "toxic" effect of castor bean plants I forgot to add that the plants are supposed to keep moles away.
It doesn't work om my property. My mother did pass away at the age of 96. I had not thought to attribute her passing to the castor plants she grew.

quepasa, I think you have hit on one of the primary keys. It can't hurt. Much of the ado about synthetic oils seems to be the frantic search for the solution to a problem that does not exist. Some of these guys report all kinds of problems form use of castor. I have experienced none of them. Further I can't seem to duplicate them.

Some have written pages of their research and posted quotes from various authors to support their views. I sincerely hope those people know all that stuff due to their profession or other background and have not devoted that much effort and research to the pursuit od a debate about one aspect of a hobby. A debate that will change no minds anyway. I would applaud such zeal in the search for a cure to a deadly disease, but keeping a small recreational engine lubricated hardly seems worth an obsession.

Status: offline 		You know jessie....these fuel mixers don't say squat about the synthetic oil in their
fuel...or just what the heck brand it is. You would think they would be shouting from
the roof tops about how...." I blend with Super Zoomer synthetic oil, and it's the best,
and it has such and such properties of this, that, and the other".

They don't say squat....and in fact most won't tell you what they use, nor will they give
you the properties or specs of their wonderful oil.

There must be a reason for that. Probably if we had the specs, we wouldn't buy the stuff.

Plenty of folks have mentioned the names of the synthetic oils they're using with great success.

Coopers, Motul, Aerosynth, Aerosave -- these are all synthetics that offer significant improvements in performance and protection when compared to the Klotz and Morgan synthetics that most N.Americans associate with the term "synthetic oil".

Our entire club has been running their engines (predominantly 46-sized but also a few 90's, 100's and 180s) for over a year on fuel with 12% Coopers Plus C and we've had *zero* mechanical failures and no indication of unusually high wear (in fact we seem to be experiencing *less* wear than when we were using Klotz/Morgan oils at 20%). And we're talking about a group of fliers who range from "just learning -- (what's a needle-valve?)" to keen 3Ders who load up a .46-sized engine with large 12" paddles, and hardcore fliers who regularly run their engines at 16,000 RPMs+.

Even after importing a "superior" oil directly (and paying ridiculous postage rates), it still works out costing us *less* to blend this fuel than it does to blend fuel with Klotz or Morgan's oils because we can use less.

Of course we get the other benefits too -- less time spent cleaning models, cooler running, better throttle response, more power and more consistent engine handling in both very hot and very cold weather.

It's worth nothing that the Plus C blend we use *does* have a little castor -- I don't think I'd run any ABC engine without just a few percent of castor as a "lube of last resort".

Castor has its strengths, synthetic has its own strengths (especially the more advanced synths)
Castor has its drawbacks, synthetic has its own drawbacks (but fewer in the case of more advanced synths)

The final word(s) on castor should (IMHO) be: "Castor is a handy and cheap insurance policy. If you think you'll never need it, don't use it. However, if you want to take out a policy, just use a few percent and you'll get most of the benefits with few of the drawbacks."

....I believe Cooper uses one of those three other oils you mentioned. None of those
three have ever been available in the States, except very, very recently (this year) I saw
an ad for one of the oils in a search, but I don't remember which one.

None of those oils has ever, ever been displayed anywhere for sale that I have seen in the US.
Not at an auto parts store, motorcycle shop, hobby shop, anywhere. In fact I know of no place
where those oils are available for purchase, except maybe on-line.

The way the US dollar had declined in value to the Euro....those oils would probably cost a
small furtune....IF they were available for purchase.

BTW, I do use synthetic oil in my blended fuel....Klotz, which is one of the original synthetics
that have been producing satisfactory results for 40 years in the States. In the past almost all
the fuels in the states that were pink in color (and almost all of them were) contained Klotz.

Now, that is not to say I would use straight Klotz synthetic in my fuel, because I wouldn't. And
that is not to say that it is the best oil either, because it probably isn't. If I had to, I would use
Klotz Beniol for sure.

Our friend Jaka loves the European synthetics in his sport planes. However, when he races the
pylon planes....the required, specified oil is castor. Straight castor. There is a reason for
that. The reason is that there is no other oil on Planet Earth the gives the lubricating qualities of
straight castor oil in those racing engines.

There never has been, and there may never be.

I agree totally that a blend of castor and synthetic oil is the best way to go for sport engines. I
have been using the blends since 1968.

FBD.

I forgot to mention that none of the oil mixers in the States that mix synthetic only
glow fuel has ever mentioned or specifically named what brand of oil they are using,
much less the properties of that brand of oil....at least I've not seen one.

They say one word on them....synthetic.

After a while I too started to wonder what was in my commercially mixed fuel as there was bugger all on the label only that it was 18% oil mix. When I asked the store owner what was in it he just raved on that it was some sort of comercial secret and i had no hope in hell of finding out. Well as far as I know it isnt rocket science and the only way of knowing what was in it is to mix it myself and bingo all is good. Cheers the pope PS and you can save a few bucks along the way.
