Fuel Question...Age?

[Bob Pastorello]

John Ferrell -  YOU win the prize!!!  
    Just got back from additional deadsticks.  Since I had changed everything BUT the bearings, I decided to tear it down.  Although only barely used (I bought this with 1/2 gallon through it), it had OBVIOUSLY been stored improperly.  There are signs that the bearing seized or grabbed at least once; circular scuffs on the crankshaft.  The sure sign of bearings locking.
    I'll put a photo up later...but it's an U-G-L-Y looking bearing....

  I keep 0%-all Synthetic oil,  Red Max in jugs for quite a while(2-3 years). I mix it down to 10 or 15% using the same 20% fuel with no problem. The Red Max red dye goes clear the first summer in the fuel shed. 
  If you think it is losing methanol or nitro that would just make it oil rich, not usually a big problem.

  I never have got around to the matter of water testing. I have sometimes thought about testing with controlled amounts of water in the fuel just to see how much makes a difference.

  It has been my experience that when an otherwise good engine starts getting picky about the fuel, it is running warmer than it used to. In my case it was bearings...
  That is, as I recall...

    I know this is a newbie kind of question...but I've never run into this before.  Sealed (good caps, tight) jugs in the dark, Mag 1/10% mix that I use all the time.
        Ran my 1.60 fine on the ground, but couldn't get a needle, and sounded lean at high end in flight; even dead sticked a couple times.
        Changed to a jug of fresh Ritch's Brew 15% (should have been about the same nitro) and it ran a lot better, had needle range, didn't try to overheat.

    What can happen to sealed jugs, kept in temp.controlled, dark box....??
