I prefer to use the synthetic fluids such as royal purple. This becomes more important if you do any performance driving or racing with the car. The regular gear oil can get burned up running track day events or the like.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
