Can I run premium fuel in my 99 GT?

Can I run premium fuel in my 99 GT?
Just like the title says, I have a 99 GT and I like to put premium in it. Will this actually hurt the performance because the computer is set up for a lower octane? I use premium because I feel like it burns cleaner and prevents knocking. This maybe a dumb question but it never hurts to ask.

yes you can run it, but you are wasting money....it doesnt burn cleaner (atleast i havent heard this..i could be wrong?), and it only prevents knocking if you have your timing bumped...for a stock tune, you should be running 87, your not going to have any detonation

Ok thanks, I will def. go back to using 87. What company do you guys think has the best fuel? I have heard that BP has the highest oxygen in it, clearly you know why that is good for a combustion engine. I wonder if that was just made up or is it really true?

Also, I forgot to add. When I turn my A/C on the car just doesnt run right. It feels like the power is cutting in and out at weird intervals. I know there will be a difference when running with it on but this just doesnt seem like it should be happening. Any of you experience this same problem? What can I do to stop it?

fuel: run whatever you want...but make sure to try and run that same brand consistently...they all have additives, so sticking with the same brand doesnt mix them all up in your car
for the a/c...try to clean your IAC valve... my IAC was so bad if i was idling and i flipped the ac on and off rapidly 5 times the car would actually stall out

hey I new to the forum and I should say whats up. Hears my opinnion, have you checked the diff. in mileage from 87 to 93. The 93 you will get better mileage than 87. and your engine will be cleaner. (not as much carbon build up) i get 230-240 miles a tank on 93 and 190-200 from 87 give it a try
