Status: offline 		A friend gave me a new sealed gallon of green Cool Power 15%. It does not say "Heli Fuel" on the jug but he told me that his hobby shop sells it for helicopters. Would it be OK to run this in my Raptor with the stock TT engine? I have been using the green Cool Power that says "Heli" on it and it runs fine. Any help would be appreciated. Pete

Status: offline 		the Cool Power 15% and the Cool Power 15% Heli are the exact same fuel. Only difference is one has a Heli sticker on the jug. The fuel labeled Heli and the 15% Cool Power cost the dealer the same amount. So the dealer should be selling the 15% and the Heli for the same amount.

I've been told cool power skimps on the oil content and... - 7/2/2002 7:39:18 AM

Status: offline 		I was using coolpower 30% in my raptor ran great yes but. I then switched to wild cat and then I had to really richen up. I asked my friend mr wizard and he stated that cool power doesn't state it's oil percentage and have been caught with thier fuel low on oil content. I like the wildcat way better an it smokes less cause it's synthetic. I was told that folks having run problems the first thing the techs ask what fuel if you say cool power they say it's fuel if you say wild cat it's not the fuel. Just what I heard I don't care either way in opinion I think the wild cat is way better 30% nitro&18%oil good luck

Status: offline 		Duh - You had to richen it up because you had low oil content with the Wildcat. Cool 30 has 24% oil content and smokes like heck because of it but also protects those hot running engines. 18% oil in 30% Nitro fuel smokes less because there is less oil and seemingly less protection to go along with it. Given the hotter temps that Heli engines often run at I can't see the logic of using the bare minimum of 18% lube in a 30% Nitro fuel. It doesn't make sense. Repeating "hear say" rumors about what you heard from your buddy Mr Wizard criticizing Morgan Fuels for shorting customers in lube content is irresponsible and a complete falsehood. Cool 30 may possibly be the most popular of the high Nitro Heli fuels. Lots of those truly in the know use it and like it.

Status: offline 		I agree 18% lube with 30% nitro sounds like it is way low on oil, talk about skimping! Coolpower 15% has 17% synthetic lube if I am correct!

Why do the engine manufactures recommend 18-20% oil? 18% is more than enough do some research on oils you'll be amazed at what you don't know.

By the way cool name! There is a distinct difference in low viscosity oil and high viscosity oil, and yes protection is the key. The higher viscosity oil protects better. I also think Mr. Wizard was a really cool guy, could be why I ended up being an Aerospace Engineer and taught at a major University....I also like McGyver...way cool.....and duct tape!

Den, you had to richen up because of the oil viscosity, being "thicker" the fuel needs more room "richening" to get by the needle.

Less Smoke/More Power/Superior Mid-Range - For years heli pilots associated good lubrication with large amounts of smoke, this is simply not correct. Oils used in R/C fuels can be of different viscosities (different thicknesses or weights) some fuels use large volumes of less viscous (thinner) oil with the idea that since the oil is thinner the engine will be able to accelerate quicker and the greater volume will make up for the reduced protection that the less viscous oil provides. In a few respects this is true, but the penalties outweigh the benefits. By using the less viscous oil a much greater volume is required for lubrication, this in turn reduces the amount of burnable fuel available (the oil does not burn) and thereby reduces power. Usually the result is the pilot over leaning the engine trying to extract the power. The larger volume of oil also produces excessive smoke (carbon) during combustion. WILDCAT uses a more viscous oil at 18% volume. This oil better protects the piston with a stronger shear strength and load carrying capacity lubricant. It also provides for a better seal between the piston and the sleeve, this in turn allows for higher compression due to the reduced blow-by ie.. more power. Because we use a more viscous grade of oil we can use the 18% volume, this allows more methanol and nitromethane (fuel) for the combustion process ie... more power. By using a higher viscosity oil we can use the recommended amount that meets and exceeds most warranty requirements including the popular OS heli engines. Using a more viscous grade of oil also provides for our next benefit, better heat removal. In straight forward engineering terms the greater the viscosity the higher the heat capacitance. In english, the thicker the substance the more heat it will absorb in a given amount of time. The higher viscosity oil can simply carry away more heat from the engine. Once again, this provides for a cooler running engine that will make more power and transition better.

Hope this helps your discussion.

Status: offline 		I got remarkably better runs and more power with the cooler temps on Wildcat 15% than CoolPower 15%. Hands down a much better perfomer. At least it was in my OS .32.

Although, I find that the CoolPower 30% runs better than the WildCat 30%. I wanted to stay with Wildcat but it just didn't cool as well. The power was marginally lower than CoolPower as well.

I fly in the Hou, TX area where the humidity is VERY high along with 90+ degrees and starting to warm up. We all fly CoolPower 30% down here. But, the Wildcat 15% is truly the best 15% I have EVER used.

Powermaster is available but I never felt that it would run good in helis. Ran OK in my planes but it just seems to high priced by our local guy to mess with trying on my helis.

Status: offline 		I got the most power out of power master.. then all the others. BUT I havent tried wildcat YET! ~S~ I was living in Calif in HIGH ALT.. But now I am in IOWA with VERY high humidity and its around 95 degs as well..
But this was also 8 years ago.. I found that power master in my OS 32 was awesome ! campared to the cool power I was using at that time.. both were 15%
Today I am finding that the cool power 15% is doing OK here is IOWA
but not very much power tho.. from what I am used to..

Status: offline 		I'm having trouble believing this argument of less oil needed if its of higher viscosity. The other fuel makers who have been around a lot longer than Wildcat don't seem to subscribe to this notion at all or they would be doing it right now. Perhaps I should start using only 2 quarts of sae 70 weight in my car rather than 4 quarts of sae 30 weight?? - There is something cockeyed about this theory. Powermasters fuel facts is an interesting read however why do they only offer fuels with the same or higher lube content as others do?? It kind of deflates their explanation of what lube content is actually needed doesn't it?? Still, Powermaster is an excellent brand of fuel. Does Wildcat have a website that details all their different blends and has mail order pricing info?

Where do you get less oil ????? The engine manufactures recommend 18% that's what wildcat uses.
