Prolly 'cause they are using leaded fuel.  If not that, then I don't know 
why.  I can't believe its the heat since rotary engines produce even more 
heat with no loss in O2 sensor life.  I don't _think_ excessively rich 
mixtures will reduce the lifespan too much, but I was wrong once or twice 
before...  :-)  (Contrary to Bob D's belief  :-)
