2008 Pontiac G8 GT: Needs Another Quart
April 28, 2009
I checked the oil in our long-term 2008 Pontiac G8 GT today, and it registered below the low mark. I've come to know that this means the car is down a quart . So I gave it a bottle of 5W30.
Believe it or not, we haven't been neglecting the car. Oil service intervals are computer-indicated on the G8; there's a shot of the owner's manual in the thumbs below. And since its last service at 11,800 miles, the maintenance light has yet to illuminate again.
A check of the Edmunds Maintenance Calculator suggests that 12,000 miles is the absolute longest you could expect to go between changes and the owner's manual notes that you shouldn't go longer than 10 months -- we've reached neither threshold.
