Who has some real world time with Cool Power. Can anybody tell me why some call it Cruel Power? I can't imagine the LHS running it if is that bad.

After running a few gallons of cool power through an engine, the insides will turn a nice green color. Very cool.

(The parent company of Cool Power has several different brands) Anyway, I have used a number of different fuels and found that most are very good. More a matter of personal preference, price, and availability. Just my two cents.

But really not that bad for ringed two strokes, if you keep it on the rich side. And it may not be that bad for the Saito, but it will void the warrenty. And they can tell if there has been no castor in the engine. With castor the inside of the case will have a nice rusty gold color.

The manual of my Saito 91 does not mention anything about castor oil. In the fuel section it says to use "a high quality 2-cycle fuel like, Omega, Cool Power, K&B, Power Master, etc." Omega has some castor oil in it, but Cool Power doesn't. So, I use whatever I find locally and make sure that it is not lean.

Happy flying.

Status: offline 		In the heli world, I am getting some reports of bearing failures (OEM and mine) by people using Cool Power 30% heli mix. I attibute this to it haveing an extremely low viscosity oil (somewhere near 5W). Most other fuels use oils with viscosities in the 20-40W range.

Castor is as thick as 50W motor oil when cold. I don't know how much it thins out hot, but have a hunch it does very well.

Status: offline 		Castor is the only oil allowed in both FAI Pylon and FAI CL speed where engines are turning upwards of 40K revs and fully peaked out. These are the most extreme conditions our engines can ever run in and no one complains about the oil.

In CL stunt where engines live a very easy life running in a 4 stroke all the time no one will even consider using Cruel Power (or one other brand known as the Red Death) because very long and consistent engine life is needed.

Status: online 		I run and fly mostly small engines. The last few years mostly 1/2A and mostly Norvels. My experience with fuel in the smaller engines is that yes, castor is necessary in SOME engines, notably the Cox line and the VAs from Russia. The issue is the shrouded wrist pin with the VA and the ball socket rod with Cox. In both cases, there's much less fresh fuel/oil circulating in these areas because of the design. If you DON'T use lots of castor in these engines, you'll have premature wear.

HOWEVER, in the Norvels, I've run Cool Power 25% for a few years now and have not had any problems. In fact, I've found superior power, idling and acceleration with Cool Power.

The worst fuel, at least for 1/2A, was Byrons 1/2A formula. Same day, same prop, same engine and the CP was far superior. In fact, the Byron was the worst fuel these engines had ever seen. On top of that, the Byron was specified for 1/2A and the CP is NOT. But Norvels are unique, won't say the same thing for any other brand of small engine.

On the same note, I had run, for years, Morgan's 25% Sidewinder fuel on small engines with no problems whatsoever. And many of these were Cox engines. Go figure, especially in that Sidewinder fuel is for CARS and has only 10% oil. And recent flying with Sidewinder on a Norvel .074 has shown good power and good throttling. ??? Beats me.

But I DO like Rich's Brew, especially in that he'll mix up any formula you want,, like 60% nitro with 25% castor. Just what I needed for TD .010s and TD .020s. Throttling is much improved with the increased nitro. Yes, expensive, but not on a per flight basis.

Here,

You can see a custom heli engine turning a 6 X 3 Grish prop at 19K plus on 25% Cool Power. Not bad. Same goes for a modified Brodak .049 in one of the other videos.

Status: offline 		Thanks Andy. I have not used up the old fuel to start on the Cool Power yet. Next month I should be onto it. You and others have reassured me.

Thanks Again,
David

My son and I have used CoolPower in our 14 engines for the last 2 years. We have 4 Saitos (1x91, 2x100, 1x180), 6 OS 2 stroke airplane (4x46AX, 1x50SX, 1x61FX) and 4 OS 2 stroke helis (2x32SX-H, 1x50SX-H, 1x91SX-H).

We use CoolPower 15% 4-stroke in the Saitos and regular 15% in the OS 2 strokes. There is no difference between the 15% and 15% heli (see the FAQ on Morgan's web site).

I switched to CoolPower after the 50SX burned its rings twice running 15% S&H. We were not running it lean. Since then, we have run easily 7 gallons through the 50SX alone and had absolutely no problems and great performance. The helis and the 4 strokes work beautifully. Two of the 4 strokes are in Funtanas. The 91 is in my Funtana 40 and the 100 is in my Funtana 90. The 91 has burned several gallons of gas as my primary plane.

No question - CoolPower is the only fuel I would use. Small problem, though. I have just moved to California from New Hampshire (more flying days) and I can't find a dealer in the Pasadena area that carries CoolPower. Anyone?

Status: offline 		OS 1.60 Ringed engine. 1 gallon of 15% Coolpower sloppy rich OK

2nd Gallon of Coolpower, maybe ONE lean run and damage to both ring and sleeve -- NO MORE COOLPOWER for me.

Since then I have been running Wild Cat Xtra Premium 15% in ALL of my engines except 2 of them -- no problems at all. (I don't mind the castor varnish on my heads and mufflers)

I use FAI Omega on my Moki 180 -- it is not running well right now so school is out on it.

I used 50% Methonal and 50% Wilcat 15% Xtra Premium on my Super Tiger 3000 -- ran great.
