That's  different than the green stuff the original poster reported finding
in his  car.  My understanding is that the orange extended life stuff  should
only be used if you do a complete flush of all previous products  from the
system.  Otherwise, it mixes with other types of antifreeze  to form plugs.  


Yes, but, the discussion has also centered around the question as to  whether 
any antifreeze other than Pentosin is acceptable.  If the Prestone  Extended 
Life (orange color) is not acceptable, I'd like to know why.  
 
thanks,
