2MuchThrow,
I couldn't agree with you more. I can't even get past the "To Castor Or Not To Castor" question concerning four stroke motors let alone how much nitro or oil content. I was running CoolPower 15% in my Saito and then was told that 18% oil was not enough. Oh my goodness it is all synthetic as well. I know better than to overheat a 2 stroke so, for me synthetic was fine. Besides, Castor in a 2 stroke ringed motor just means you will gum it up and spend more time sooner fixing that.

I think we need a manufacturers rep from all of the four stroke companies to recomend at least a safe percentage of castor/synthetic/nitro blend without the wishy washy this is ok and that is ok and no real recomendation. To complicate things, some fuels are great about telling how much of what is in which products in their line. Others are not so good.

So what is the best fuel for our nitro swilling bump stickers? Is Blow-By a really good lubrication method for a crankshaft? With that much Blow-By, arn't we loosing some of the power potential? Seems to me that my four stroke is bordering on if not surpassing my 2 strokes in fuel inefficency when you compare how much raw fuel and oil are deposited on the Ultracoat.
