I burn five to six gallons a year and I just can't see mixing my own to save $20 a year. I may change my mind on this though. My last case of Omega 15% cost me $16.75 a gallon at the local hobby shop. I've only got a gallon left so it's time to start looking again. Like you Grey Beard, I fly four strokes and It is so nice to just make a click or two of adjustment between the end of one jug to the start of the next.
A while back, one of our club members left a couple unopened jugs of Cool Power 30% at our field. I grabbed one, but I'm not a cool power fan. I've heard that the nitro goes bad after a while, even if it is unopened. So If I lost half of the nitro goodness, Think this stuff would still be good after four or five years? I bought out a guys entire hobby a couple years back and there was a case of Towers's version of Omega 15% that was at least seven years old. It burned very well until the last tank of a jug. I was flying more then and a jug didn't last so long. So, how about mixing old and new fuel? A jug of iffy 15% and a new jug of 30%. Just a thought, looking at about five gallons I'm not sure I can use.

If the old fuel was kept sealed out of day light and cool it will stay good for a VERY long time (some guys have used 25 year old fuel)
