If it is left stock you will NEVER kill a gtp by running 87 in it. My ex girlfriend had a 98 gtp that her parents drove off the lot in 98 and passed it down to her. I never really asked what fuel she ran in it untill one day I filled up for her while she was in the car (-15F outside) and then was confused / a little mad that I put premium in. She had no idea why you would ever need premium until she got on it and noticed an immediate and very real power increase. Asked her parents later that week and they said they never put premium in it either. That thing had 238,000 miles on it. It didnt even have 4th gear for the last 40k. Engine was absolutely perfect.

That's cool if you stay out of boost...
