I had a new Saito 1.00 two years ago in my new H9 spitfire mounted inverted I used cool power pro 20-20 fuel and it ran perfect from the first start up until now and is still running strong .

I thnk the point to all the answers is, as long as the engine is in proper tune it doesn't care all that much what brand of fuel you use. If you switch to 10% XXX and the engine starts running rough then tune it. Like Frenchie said, it's more about set up then fuel. I haven't seen any engine harmed by using store bought fuel and it all seems to run about the same, alcohol and nitro is all the same stuff, the oil blend can and is usually different but none of the blends seem to make a lot of difference in how the engine runs if you tune for it.
