What do all the specifications on your typical container of oil indicate?
SF/SA/CC/CD, etc, etc.  A label on my engine clearly indicates that I 
am not to use oil with specs CC or CD (a label so strategically placed
that I noticed it after I had been running some CC/CD for about 30 
days.).   During the 30 days I ran the CC/CD oil, my car produced major
amounts of bleu smoke after idling for more than 10 seconds -- as soon
as I put in some SF/SA, the smoke disappeared, and I'm happy again.
The questions are:
   What is the significance of the specs,
   and why did my car smoke (it's a Turbo, if that matters)?

Thanks in advance!
