Types of coolant to use...

[mr.utility at highstream.net (David Utley)]

The have a newer version of this coolant that has come out since the article 
was written...  It no longer needs to be a reverse flow type set-up or the 
overdrive pulley, in all but the most extreme cases.  I have only had the 
engine ping once, when it was 95 plus degrees out, but I could not duplicate 
it after that on hotter days.  BTW, this is a lower comp. motor, and I always 
use 93.  Granted these are ideal conditions for this setup to work, no turbo 
or 'charger, but I do know that another friend has it on his high-comp 
Cabriolet, with the same amount of advance, with no pinging...

Just to continue the friendly debate here...  :-)
