Is the new Mustang engine not built to run on regular? As I understand if this car is built to run on regular, premium would actually end up damaging the engine right?

There is a higher metalic content in 93 octane fuel.... which can damage a motor that is not designed to use that fuel.
In the owner manual is says use 87, that's what it was designed to use... but then it says if you experence any pinging swich to a fuel with a high octane level....? :scratch:
I really think they are watching their own butts on this one..... B)
At any rate I have been using mid-grade fuel, and I have not had any problems....
But my mpg, is not what I expected as we all have talked about in other threads.

Uhh, I dunno exactly who said it, but putting in a higher octane fuel is not going to damage the engine. The engine comptuer has knock control sensors .. you can even run regular fuel in most premium requiring cars and they'll run okay because the computer will compensate. There isn't really any damage you could do if you ran higher octane in a lower compression motor. Just the other way around .. but even then it wouldn't make much difference.

Older cars have more carbon deposits which lead to hot spots, leading to pinging.

If a manufacturer recommends lower octane gasoline, there is seldom any advantage at all to spending more for higher octane. It's the fuel industry telling us what we want to hear that sells the premium fuels, with the exception of engines that require it according to the builder.
There's actually a math formula based on displacement, compression ratio, etc. that tells you what fuel the engine will require. If I could just remember it. . .

No math error, I calculated it myself, of coarse i forgot to check my on board computer (DUH) and it stated the same numbers.
Strickly highway last weekend I think it was in the low 20's. After I switched over to amsoil, I think gas MPG improved a little bit. I think I was getting 15-17 combined before the change. I know for sure my F-150 got better also when I switched over.
