How many of these mileage posts are there?

Anyway, I average above 25mpg with an '03 GT that I shift around 3k for every gear that's applicable to the speed I'm getting up to. I also tend to use the cruise control whenever possible and try to keep the cruising rpm's under 2k (unless I'm in hilly terrain, then I keep it above 1750 or so).

HOW? damn. I get like 200 per tank. around 14-15 city (ouch), and like 25 on highway.

I'm consistently in the 13-14 mpg range with 90% city driving.

Nitti00GT

Yeah same here. I'm always in the 12-14 mpg city range. When I'm not even getting on it I still get about 15 mpg.

the guy that says hes had 366 on a full tank most likely drives like a grandma..and in that case why own a mustang ?

How are some of you gt's getting 25+mpg on the highway?? I get about 21 cruising at 75mph. Maybe it would be a little better if I was going 70mph?

I can bet its your a/f ratio out of whack. This happened to me before when I had my MAC CAI. The bend before the MAF causes the MAF to get an incorrect reading and it kills your gas mileage as well as HP. I put the K&N FIPK on there and I saw better gas mileage with more power.

My car gets better gas mileage with the supercharger on it! I have definately seen an improvement lately but I havent been getting on it either.
