I bought 20 gallons of Morgan Cool Power fuel stationed in perfect conditions for 20 years! Only one gallon bottle has a label stating 10% Nitro. I use it in my Citation / OS 61 VF with excellent performance. I have told there are one gallon bottles with different amount of nitro (5%-10%-15%-25% and 4=%)
My question: Is there a FUEL GURU could help me how to know
approx.percentage of nitro in each of the bottles? Could it be a chemical analisis to determine quantitatively the amount of nitro in a specified amount of fuel?

Very difficult for the average person to do a chemical analysis of the ratio once Nitro has been mixed with Methanol.
May we suggest you write direct to Morgan Fuels (http://www.morganfuel.com/ ) detailing the label on each container. Morgan (CoolPower) should be able to answer your questions.

Thank you A.T. for your answer. I agreed with you that is kind a difficult task a chemical analysis, but I hope to get some simple way to find out how much nitro is in each of those containers. Could it be to measure density ?
I will contact Morgan Fuels directly.
The point is that 19 out of 20 of the 1 gallon jugs have no label sticked to them.
