Sort of defeats the purpose of having a Mustang?

Some might say that but when your trying to save money and this is the most fuel efficient car you have and you can't afford to buy something that gets better FE and when its slower than crap anyway...

You might consider treating the engine and trans with Motorsilk. Trying some fuel additives.

Haven't heard of that have to look it up. As for fuel treatments I've tried different things for a while now and have seem to hit a wall with them so im just going to back to my usual can of Seafoam in the gas at every oil change (3000 miles).
