What gas does the 2003 Pontiac Grand Prix take?
It depends on the engine: regular gasoline for the 3.1L 6-cylinder and 3.8L 6-cylinder; premium gasoline for the 3.8L 6-cylinder supercharged.
Key takeaways
- 3 EPA-certified configurations listed for the 2003 Pontiac Grand Prix.
- Rated on premium: if the owner's manual says premium required, use premium; if it says recommended, regular works with some loss of power and economy.
- None of the listed engines is flex-fuel, so do not use E85.
