Subject:      Stupid question about PENZOIL

As I was perusing my Bentley manual I noticed that he says motor oil "used in 
1975 and later cars must be labeled 'For Service API/SE'".  What does this 
mean?


I checked the PENZOIL GT Performance 20W50 I'm currently using and it says 
API Service SH, SG.  An older case of PENZOIL 20W50 I had kicking around 
(doesn't way GT Performance on it) says API Service SH, SH/CD, SG, SG/CD.


So here are my questions:


1) Anyone know what the difference between PENZOIL 20W50 and PENZOIL GT 
Performance 20W50 is?


2)  What do all these API Service acronyms stand for?  SE?  SH?  SH/CD? SG? 
SG/CD?


3)  Am I using the wrong type of oil?  


Thanx.
