The Cobra's require 93 octane for fuel, is this the same for the GT's, or can 87 be used for those cars if they are stock?

GT's can run on 87 octane just fine.
low compression motors can make the same power on 87 as it can on 93, according to Bully Dog.

if a car asks for 87, don't run anything higher, some cars it will hurt performance.
what do you 94/95 cobra guys run for gas? I use 87. When gas was really cheap I was running 93 for a couple weeks but I noticed absolutely no difference so I went back to 87.
i run 93 octane..i dont think thiers much difference
I run 93 also scared to run 87 dont want no knocking but mine is a 96.
96 you need to run I guess a min. of 91 if your stuck in Cal., anywhere else if you can get the 93 go for it. The 94-95 should run on 87 unless you advance the timing then you need to run 89 or prem.
5.0's cobra's and 4.6 GT's run 87 unless you bump the timing.
4.6 cobra's run 93. Any less and you will get pinging and possibly bigger problems.

wth the Knock sensors in our car you should be able to run any thing, if it detects knocking/pinging it should just back off the timming....right....?VirtualSVT said:
It will but that is reactive, not proactive.1996_Snake said:
Knock is bad. You don't want it to get to the point where the Knock sensors pull timing.
My bro has been running 91 on his N/A 94 5.0 GT...so he can run 87 with no problems? Wish I could run 87 on my cob$a...lol

in some parts of orange country you can get 92 octane right at the pump! lol, exit off of brookhurst on the 5 freeway!
i wish we had 93 at the pump
I run 91 here, only cause my timing is at 12-13 degrees.
92-94 depending on which pump im at. Have run 98 at the pump when i didnt have cats and with some timeing changes. You could look into tolune as an addative a couple boosted cars around here are running a toulene+92 mix so they can run more boost
