Gas does and will matter in your GT ! The owners manual reccommends 91 octane . If you go lower you risk pinging and/or possible engine damage. What most people have noticed is that going much higher doesn't really enhance the engine performance in stock setup. However in my area I have a choice of 89 or 93 octane and noticed a definate difference when running 89 so I stick with 93.

Welcome to the forum <img src=icon_smile_cool.gif border=0 align=middle> and enjoy your new ride.

Gas does matter so stay with 91 or higher octane. After all, most of us purchased the GT to get optimum performance. I use Chevron Supreme gasoline (92 octane) with good results.

Same here...

I have read in the owners manual that you can safely run Regular unleaded.

Check your Owners Manual to be sure!

However,it does cause some slight pinging, which isn't worth the approx. $1.50 per tank savings.

Also, I have read somewhere on the message boards that running octane higher than 91 is Not recommended.

Many stations here only offer a choice of 87, 89, or 93 octane, so I personally use 89.




Enjoy the ride!

In using 89 octane does the phrase "possible engine damage" ring a bell? Do you think the pinging sound is just innocent noise? I haven't heard or seen that 93 octane is bad. A lot of GT owners use it. Look on the inside of your gas door. It says use premium gas. I'd hate to see you damage your engine by using 89 octane.

I've used nothing but 93 since mile 1 and the only sound I hear is the tires chirping.

Nothing but 92 here!

Accidentally put one tank of 89 in my turbo. Performance was noticeably reduced. Use 91 octane and plan to stay with it.

I too used 1 tank of 93 and noticed a drop in performance[8)]
