Default Cool Power 4 stroke fuel; nitro and oil content?

Can anyone tell me what the nitro content of CP's 4 stroke fuel is? Also the oil percentage?

I checked Morgan Fuels website but couldn't find the info there. The gallon I have is not labeled for nitro content. I'd like to know if I can use it in my 2 stroke heli engine. But before I do I need to know the facts.

( I have heard it's really not a totally synthetic oil but rather a blend of castor/synthetic....but i am not sure 100% of this)

Jbrundt,
I avtually called Morgan's on that and it took a while to pry it out.

They told me it was 15% nitro, 17% oil. The oil was a 50/50 blend of synthetic and castor.

I am only passing on information that they passed to me.

I have a few gallons of WildCat 2/4 15% with 18% full synthetic and have used WildCat 20/20 full synthetic as well as Fox 5% with 20% 50/50 and what you're saying simply is not true. 20/20 full synthetic is the recommended fuel for YS engines and if any engines were to run hot it be them and they don't.

Considering that the OP asked the question 11 years ago....more than likely he has discovered the correct answer by now!

Considering the thread was resurrected, likely because of a search that many users often suggest, to find an answer.

The only time synth oil will cause the engine to overheat and consequently not last as long is if its ran too lean for too long. Otherwise it's mostly bogus.

Yeah, synthetic works fine. Unless you have a lean run. But in RC you just shut down and land. In control line, you can easily ruin an engine with a few lean runs and no castor. With some of the older iron piston/liner engines, you really do need the castor (and lots of it) - in fact, if your engine is an older, well used iron piston engine, one tankful of synthetic oil will ruin it - by stripping away all that varnish that was providing the compression!
