Ok, I am glad I am not losing my mind. My confusion over fuel really started the first night I went to my club field. My club has an intro pilot program where they supply the trainers, you supply the fuel. Although I technically had a plane the first time I went out, it wasn't assembled yet. I did however bring my fuel so I could fly. According to our club website they requested 15% fuel (nitro content). Well I arrive at the field with my pink fuel in hand ready to fly. I was promptly told that my fuel was not the "correct" fuel. They then proceeded to pull out a gallon of the green stuff (Cool Power). Not really understanding why mine was wrong as it was 15% nitro like they suggested I asked one of the member what the difference between the pink and green fuel was. He wrongly told me that "pink" fuel is 10% and "green" fuel is 15%. As I said I didn't know any better so I accepted his response as gospel until I repeated the information a couple days later to a friend who also flies. He corrected me, and pointed me to the Morgan Fuel website. I spent a lot of time reading every word on that site, but was still confused. I finally just resigned myself to trust the guy at my LHS since he sold me everything together, so he knew exactly which engine I had. I am glad to know that my trust was well placed.

I must admit though, I am still a bit confused about what the best application for synthetic fuel is. I see a lot of our Heli pilots using Cool Power, as well as some of the plane guys. Does synthetic work better for 4 stroke engines, as well as ringed? Is there really much of a difference? Could I safely run Omega on all engines I might buy, including ringed and 4 stroke? I did take a look at several of the engines I have looked at buying(all 2 stroke), and only 1 or 2 of them are ringed so for now I can continue to run what already use, but I would love to understand this more. So many of the things you buy in this hobby are just expensive enough that I would hate to ruin them because I didn't know any better, and as my story from above shows my club isn't always a reliable source of information.

I don't remember who said it but one of the first comments I read on RCU went something like this: If you ask 10 guys at the field their opinion on something you will leave with 12 answers. I guess that applies to fuel as well.

Thanks again to everyone here who helps us newbies.
