Why GT's Run on Regular?
Hey guys, whats up I was looking at a speedodometer and it was on a 04 Mach 1 why does the Mach reaquire Preimum Fuel? It says Preimum Fuel Only but why do our GT's Run on Reguler I rarely Run Regular in my GT but I still feel a difference seems like my GT is Slugish on Regluar So i always put in Super or Preimum Why dont the Machs take Regular?
That's right.

Its all in ur head. You dont feel any difference in fuels unless you put in fuel from a raceway or fuelmart or other no namebrand fuels. Exxon shell amaco ect 87 will burn PERFECT in ur gt. Thats why your manual reccomends it. Would ford reccomend 87 if i didnt run right? I think not.It actually leaves deposits in your engine if your compression isnt high enough to burn higher octane.

Higher compression N/A motors (Mach 1) and forced air motors (Cobra) require higher octane fuel to avoid detonation. If you're not familiar with the term, detonation is that wonderful event that puts holes in pistons (if you're lucky) or ventilates your block with a connecting rod. Of course, neither one is a good thing.
Ford engineered the GT to run on 87 for a reason: it's cheaper. You can now buy your GT, pay less at the pump, and feel good about the money you saved. Quite clever sales gimmick, really.
You can run higher octane fuels in the GT, but you get no gains from it. However, you may build up residue on the valves and exhaust runners. I believe it is carbon build up. Correct me if I'm wrong folks.
If you advance the timing, you'll want 91/93 octane in your pony to avoid detonation. I know you can advance the timing to 14 on a N/A car, but is that on 87 or 93 octane? I never read anything about the grade of fuel in the articles.

You can advance the timing on a N/A GT by at least 3*without lighting a CEL or any detonation and still run 87 octane.You can also pick up about 2 mpg by using a Steeda timing adjuster.Personal experience.
