I believe that most of us understood that = leaded=20 gasoline can lead to spark plug fouling.   It turns out = even with=20 the "Scavenger" compounds it apparently will still happened.  = See=20 article below:
 
I also read one report that address aircraft = engine=20 effect.  It basically said that if the CHT is not kept over = 350F the=20 scavenger effectiveness is minimal.  So this may be why = aircraft=20 sparkplugs do not seem to foul as often as the auto plugs (higher=20 CHT).
