Use a minimum of 91. You can use less if you are in a bind but try not to boost and try not to run it hard until you have 91 or up in.
Unless you own a GTP, regular unled is good enough.
I have a 2004 Pontiac Grand Prix GTP Comp G Supercharged, and it reccommends premium gas, but it does fine without it.
16 city, 25 hwy. will vary depending on the driver
I would not use anything less than 89 Octane
no. but it is recommened because of the higher octane its better for the supercharger and you will consume more power.
It is located under the drivers side floor assessable from under the vehicle.
18 gallons of regular gas. I used to drive one. GTP's use premium because of the supercharger.
It is possible to use Regular gas but if you get "the knocks". you will have to use Premium gas.Use premium if you want to access every H.P.
