When you say positive track thats a GM play on words for Limited slip, which means you have both rear axles being sent power.
Which limitied slip do you have? A Clutch disc style or a Helical style
The helical or gear driven style needs no special additives
the clutch style does need a additive
Where are you located?
If you're in say AZ you may want to run a 90/110/140 weight oil to better deal with the heat.
If you're in MA, you may want a 70/80 to take better advantage of the cold.
