Do you have to put premium unleaded fuel in a 1998-2002 pontiac firebird?

[Jose]

I don't really want to buy the expensive gas so could I put the regular unleaded fuel instead?

which engine is in the car? a V6 no, a V8 yes

I didn't think premium was recommended for either...?

In a previous post Jose mentioned a V8 and again mentioned a year range which leads me to believe he is shopping for a car and doesnt have one yet. Typically the answer is inside the fuel door assuming the decal/paint hasnt worn off. That generation had an LT1 V8 and premium was the recommended fuel.

Pretty much anything these days will run on 87 Octane fuel ..
you may notice a little better performance with Premium fuel but it is NOT required as the computer will compensate for detonation and poor fuel quality..

The Firebird/TA dropped the LT1 for 97 in favor of the LS1.
