<< Hello, my name is mike (N99476), and would like to start mixing in some autofuel with avgas. My 415c is approved and converted to support this. My question is how do I insure that the autofuel is alcohol - free? Is there a particular brand of fuel that is recommended? Or any that should be avoided? thanks for any and all help >> Hi Mike: The following is off of the letter that was with the EAA STC for my alon. Measuring Cup Method. To nine (9) parts of the gasoline sample (36 ounces or 1 quart plus 1/2 cup), add 4 fluid ounces(1/2 cup) of water for a total of 40 fluid ounces in the 2 quart juice containger. Shake thoroughly, let stane for 10 minutes or until the gasoline is again bright and clear. Record the apparent level of the line between the gasoline and water. The Measuring Cup Method is intended to indicate the presence of alochol and it is not practical to evaluate the amount of alcohol. If the final line between gasoline and water is measurably, the presence of alcohol is indicated. Note: Erroneous results are probable if sample and water are not thoroughly shaken and mixed. This is how I do it: I take a pint jar use a 1/8th cup measuring cup fill it with water and pour it in the jar mark this level on the jar then add 9 1/8th cups more of water and mark this level on the jar. This is now my test container so when I get new gas I add water too the 1st line and gas too the 2nd line shake it up and let it set for 10 minutes and if the water line line has raised you have alcohol. If is the same I pump it in too the tank and go flying. Also my STC states unleaded Minimum 87 Octane. I use Texaco unleaded 87 Octane. Jim Palmer
