I have always put 87 in my GT. Will my car be able to run on 92? Will I feel any difference?

 

It would run just fine, but there isn't much point to it until you get the blower strapped on.

 

I have researched the same question in the past and from what I gather it is a waste of money. Unless you have some serious mods to your car it is designed to run on 87 fuel. You wont see better MPGs or power by doing so your just going to spend more at the pump. A car like the 08' Bullitt and even the new 5.0 have boosted HP rating with premium over 87 because that was put into the design our 2V 4.6s don't have that.

 

Good to know thanks guys. I was thinking that I would not see to much, if any difference.
