Hey everyone!
 

Hello everyone, my name is Matt and I'm 17 years old. I live in Illinois, and my daily driver is a 1998 Ford Mustang with a 3.8L V6 engine and automatic transmission. I used to be the type of guy who was big into going fast when I first got my licence, but now that I've got my 1991 Ford Probe GT turbo that I can go fast in when ever I want, I've decided that I want to get the most mpg out of my 98 stang as I can with my budget.

Now I've been kinda reading on here about some of the stuff people are doing to their car's. Well since I've already modified my mustang a little bit, I don't really know what to do to it. Like I've got a cold air intake, bigger throttle body, and dual exhaust.

So can anyone tell me some stuff that would help me right off the bat.

Welcome, Boosdprobe91!
Your biggest gains will be made by "tightening the nut behind the wheel" as is often said around here. Click on the "100+ Hypermiling Tips" link above. You won't use all of them, but they will get you thinking along the lines of how you need to operate a car to be the most efficient.
The second thing to do is to get a Scangauge II. It'll work in your Mustang, since it is OBD-II, (but not the Probe, due to it being pre-OBD-II). The Scangauge will quickly teach you how to drive more efficiently with its instantaneous feedback.

Yep, definitely pick up a scangauge II. Manual transmission swap?

Will the Mustang actually be more fuel-efficient than the Probe? Seems to me like the Probe would be a better daily driver and the Mustang a better toy!

Either way, welcome. I'm new around here too :)

Welcome to EM! I have the same question as AJI. Is the Ford Probe going to be "maxxed out" for racing or something? Using the new handy-dandy garage search engine I found some Mustangs for you to compare to :

Welcome to the site Boosdprobe91. Since you do have a fast car already, why not get yourself a nice smaller engined commuter to replace the stang? You can eek some semi-descent mileage out of it I'm sure, but it would be way easier to start with something that gets good mileage to begin with.
