fuel additives

i just read randy smiths article in the may/june issue of s/n.
he mentioned a product called "Aero-1 fuel suppliment".
perhaps randy could tell us what the ingredints are.
p. moskel m.d.

Well, Phil, I can see how these discussions could digress to the educational system.

Aero-1 is an additive that Randy Smith sells.

Here's Randy's Web page: http://www.aeroproduct.net/pricelist.htm

I don't think I care to add something to my fuel if all I know about is is an uninformative commercial name.

I'll second that, too often someone's "wonder product" turns out to cause problems at first unseen. Now if someone could just convince the makers of Baker's AA Castor Oil to make Lubricin N-1 available again at something resembling a real-world price, we could talk about a practical fuel additive that keeps engines going and going and going ...

It's got enough time on it to know that it doesn't do anything bad or unexpected to engines.

Ok, but does it have enough time that you can tell it's doing something good for the engines. Is there a noticeable difference?

With the percentage of oil we run through our engines I find it hard to believe that an additive makes any difference when it comes to engine wear. But maybe it does, anybody??

Sort of reminds me of Dura-lube for your cars.

I have been using Randy's "snake oil" for 10 or more years.
I don't know what is in Aero-1, but I think Randy did tell me one time.
Don't need, or care, to know.
Randy explained the benefits of using the product once and I have used it ever since.
A quart treats 32 gallons, and if it really helps it is a cheap insurance policy compared to buying, or rebuilding, an engine.
Only thing I can say is that the engines have never seemed to develope any rust, etc., upon storage, and it does appear to live up to it's claims.
Besides, I don't know of anyone who knows more about stunt engines than Randy. I figuer some know as much, probably, and can do comparable work on our engines, but he sure knows what to do make them run right, and last.
If Smokey Yunick were still alive, and I wanted to build a race car, I would just do what he said to do. He wouldn't have to tell me the whys and wherefores.
Although I have no empirical evidence I believe it works, so I always use it.

Bill, I didn't mean to demean Randy in any way, I was speaking of my own perspective. Since I formulated fuel blends which were sold in several Midwestern states in the '60s I'm not looking for too many other folk's advice in this area. And I can assure you that in the history of our hobby/sport a number of additives/ingredients have proven to be detrimental in one way or another.

Just a personal difference, different strokes for different folks.

Remember the exotic fuels in the sixties? Brown glass bottles kept in ice chests,for jets. And homebrewed fuel with a hint of nitrobenzene to help it mix? That stuff was outlawed because it was carcinogenic.

. . . and Harry Roe distilling tetra-nitromethane in his basement? Talk about scary . . .

Sorry, Dennis!
I was just replying to the original post after reading the others and wasn't "shooting" at anyone.
I'm just that way, I use something and it works so that's all I usually need to know.
Did sort of sound like I was referring to your post, but not intentionally.

HI Everyone,
I am not going to get into formulas, and I am not making anyone use This , If you don't feel like using it , that is perfectly fine .. maybe this will help coming from 2 guys who just bought and used the Aero-1
It has been out for 14 years, it works, it is being used by Bill Werwage, Gieseke, Fancher , Dave Fitz , Frank McMillan , Bill Rich , Hunt , Martine, etc, etc, etc......And it has been tested by me and other many times
Regards
Randy

"Larry Foster
Aero 1 Fuel additive"

I did some testing using 11½ castor & 11½ Synthetic fuel. I divided the same gallon into two 64oz quantities so the testing would be apples to apples. Then I added ½ oz of Aero One fuel additive to one of the jugs. I ran the following engines three minutes and took the cylinder temp at 4 points and averaged on each blend. LA46, ST46, OS46VF, Brodak 40 and a PA65. All showed a reduction of engine temperature of 11 to 13 degrees F with the Aero 1 additive.
My theory here is the difference in oil content between the two is only 0.005969% so the Aero 1 has to be reducing friction. If it is reducing friction then it has to be extending the life of the motors.

I've been using Randy's Aero 1 for almost 10 years now, and conducted similar tests on my VF46, MVVS40, Jett/GMA 50's & PA51 with a thermocouple and found similar results. It was enough to prove to myself that it was worth the expense of imorting. I run 1%, which is probably an overkill but my total oil content is still only 21%.
That reminds me, I'm just about out of the stuff from memory, I'll have to order more when I get home.
P.S. Hi everyone back home. I've been having a great time in Antofagasta, Chile. Moving on to Suriname on Sunday.

OK Gents just retested an LA46 the same way I described above on a Fan Break Dyno.
Fuel is 10% nitro, 23% 1/2 and 1/2
Prop: 11.5X4 APC thin blade
Without Aero 1:
RPM=11,525
Temp=238 Deg F
Torque=60.8in oz
HP= 0.695
With 1/2 Aero-1 added to 64 OZ, No Needle Adjustment, Engine restarted hot(that was fun):
RPM=11,680
Temp=229 Deg F
Torque=60.8
HP=0.705

Interesting.... 10 degrees cooler. That's a fairly significant difference. I'll have to try some, Randy are you coming to Huntersville?

It certainly seems to be doing something. Might be friction, but could also be slowing combustion and retarding the ignition timing. Might be carrying heat out like castor oil. A few ounces of castor often will smooth out the 4 stroke and soften the break, just generally make the engine run smoother and steadier. This stuff may do the same but require less concentration. If you don't know what it is you can't even guess at the mechanism of action.

If anybody is interested I've got about a gallon of PB-1 in half pint bottles. It has much the same effect, but I haven't used it regularly since I started running OS engines. They seem to run fine on straight fuel. It did a nice job in Fox CS engines though.

Maybe we can get Castrol to tell us what they put in their oil and while there at it , show us thier bottle making machine.
I,ll tell you this ; After the experience I had using Randys
additive, I,ll never fly without it in my fuel.

The article was not written to sell anything..
The article was written because of the huge amount of people asking me about fuel, oil, and how to run and break-in engines.
This is one of the most missunderstood aspects of running C\L stunt engines. and this was only about trying to help people with better engines runs, though a better understanding of fuels , oils, etc.

Randy,

No good deed goes unpunished, I am surprised that I need point this out to you.

The High Zoot crankshaft in my Fox 35 has proven to be excellent in all ways, plus I can now with complete confidence go ahead and use something other than wood props, currently using APCs, without fear of unexpected breakage.

So what are you saying dan? apc props are no good for a stock 35 stunt? Thanks Paul

Paul,

Only if you are sober will I bother explaining the obvious.

Call it tough love if you like.

Ha Ha, Well there you go again!! Paul
