I once ran a pre-mixed fuel from a very well known competitor from days gone by, he kept a 55 gallon drom of nitro to mix the fuels and is ultra expensive.
I can buy 15% for $11.75 per gallon in Bir,mingham AL LHS (closet I'm afraid) or $13.00 for 30% prices are very reasonable on fuel I try to buy a case at a time during winter and 2 cases at a time summer..You run a huge risk if you are inexperienced of getting the correct mixture Ergo is correct Wildcat is good fuel as is CP which leaves a smoke trail LoL.

PS:
Our club buys massive quanities a lot more reasonable at once after meetings we take up $$ to whomever is going to the LHS its usually me.....We have great relation at our LHS on parts availability fuels & etc..Thank Goodness we have them, and we support them as well....I put in an special order for Wildcat to Ergo...2 cases from them///...Paul thinks highly of it and I like it last time my LHS had some in..
