Hey this is a pretty simple question. The owners manual says Ford recommends BP 87 octane gasoline. The only thing I've been able to find special about BP is they are the only station in town to carry 92 octane premium. But since it recommends 87 I can't figure out why the BP. Is it just a paid sponsorship? Also I've always bought premium gas believing it burns better than 87, am I going to hurt anything by running a higher octane fuel through my GT?
A lot of Mustangs have the 'Ford recommends BP' printed on the gas cap. There is no advantange in running a higher octane fuel if the car isn't tuned to take advantage of it.
I agree with the last post, I tried both in my car and it did not make a difference. Yes Ford recommends the BP because of a sponsorship thing and because BP is spearheading the efforts for green fuel / alternative fuel. Ford gets to show it is corporate responsibility.

British Petroleum is just a big fuel supplier in the states. its just a sponsorship advertisement...no rules saying BP only. any gas will work fine...but a tune for higher octane gas will benifit you more if you decide to pay .20+ more per gallon.

As far as I know there isn't anything special about BP besides they paid Ford. If you don't have a tune/tuner it is useless to use anything above 87 octane. Before I got my tune I used 93 octane and I actually got worse gas mileage.
