What kind of gas does a 1997 Pontiac trans am use?
A 1997 Pontiac Trans Am typically used unleaded gasoline. The specific octane rating recommended would depend on the engine it had (the 3.4L V6 or the 5.7L V8). Check the owner's manual for the precise recommendation, but generally, premium unleaded (91 octane or higher) was recommended for the V8, while the V6 might have been satisfied with regular unleaded.
