Default Lube percent on package?

How do I find out what the percentage of lube is in a gallon of fuel when it isnt listed on the package? Hobbytown and another LHS stock fuels and none of them list the percentage of lube in it. I need 15% for my OS .52 4 stroke, and the book calls for 2 cycle 18% lube 15% nitro mix.

You'll have to buy it first...then pour off an amount in a graduated cup....like 1 oz or more...then let the volitiles evaporate...what is left will be mostly oil...so if you have 1/4oz left..you have about 20/25% oil.

Well that would be wasteful, especially if it turns out to be 15% lube.  The brand I am referring to is Cool Power sold at HobbyTownUsa. None of the bottles state the lube ratio.

I was able to track down the fuel they stock and it is 17% lube.  My OS book calls for 18%.  I did find one of the cool power fuels that has what I need, Cool Power MV 15%.
