So, I recently got my GTP and was reading the manual, and it says "If your vehicle has the 3800 Supercharged V6 engine (VIN Code 4), use premium unleaded gasoline with a posted octane of 91 or higher for best performance."
Now I've only been using 87, should I switch to 89 or 91, or just stay with 87?
What are you guys using?
