108 governed, 125 supercharged...
no. but it is recommened because of the higher octane its better for the supercharger and you will consume more power.
Your Grand Prix GTP needs to take Premium fuel only if it is supercharged, but you can also look it up in ypur oners mannul
It should so long as both vehicles are each Supercharged 3800's or non-supercharged 3800's and make sure the Grand Prix has a 3.8L (3800 V6) and not a 3.1L V6 (3100)
Grand Prix's in '93 did not come with superchargers. Supercharged engines were not introduced until the 1997 model year.
In my opinion, it isn't worth purchasing a car that has 189,000 miles. I would avoid buying a sporty vehicle like a supercharged 2000 Pontiac Grand Prix GTP 3800 as a first car.
A grand prix gt un-supercharged will smoke a grand am gt, the supercharged gtp grand prix will destroy it.
1999 Grand Prix has 200 HP. A Supercharged GTP has 240. These are both 3800 Series II motors.
Total Cooling System Capacity (qts): 12.3

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.
As far as i know, there has yet to be a Grand Am that has come w/ factory turbo, there were plans for a Pontiac Grand AM SC/T which was going to be "SuperCharged Touring Edition, some were made however they to were N/A
