No doubt the platinum's last a long time.  I have been trying to justify
replacing mine and they just won't die.
  
A lot of theory on spark plug technology on the last two postings, and I
enjoy reading them.  But in practice the platinum's do not work well in my
car (86 5ktqw).  I have had them for two years ,I wanted to give them a
fair chance.  Also I can't find the tri electrodes anywhere in Ont. Can.). 
The engine misses slightly at idling and just doesn't have  the zip that it
had with tri's. 
 
Some people love them, and I think it has to do with the type of driving
they do.  I drive my car to work daily, 10 minutes there, 10 minutes back,
not on a freeway, so the engine probably never reaches the temperature the
platinum's like (although they're suppose to require a lower temperature). 


>From what I read on the list, those who like them (get good performance out
of them) appear to drive their cars hard and more extensively.  I think you
have to experiment with plugs until you find one that performs well for
you, then stick with it.

For me, I will go back to tri coppers once I find them.
