   I've heard that it's better in the long run, for lawn and snow equipment, to   
   splurge on a 1-2gallon tank of 89 or 93 octane gas, because I was told it had   
   a lower amount of ethanol or mtbe in it - additives that can damage mowers and   
   snow throwers.   
      
   Any validity to this claim?
