mpg - 2003-04 Mach 1 Registry Owners Club

ramair · 01-22-2012, 12:30 AM

hello i did not know where to ask this so i quess is the best place i bought my o4 white mach 1 auto in july i love the car i also own a 1970 mach 1 so it means a lot to me to have another mach 1 but i dont think my mpg is right for the 04 easy driving 200 miles to a tank of gas which is 14 to 15 miles to a gallon is this normal all stock with 121xxx miles thank in advance

LXS · 01-22-2012, 12:40 AM

Is this all/mostly street miles? Freeway miles? Mix? Which brand of gas do you use? Have you changed your fuel filter? Have you given it a tune up since you got it?

I noticed that I was averaging 200 miles a tank when I messed with the smog/emissions lines. Once I reconnected/routed the stuff correctly again, it went back up to 220-240 a tank. If I do mostly street driving, I've seen it as bad as 180 to the tank and as much as 220. Freeway miles, as low as 220 and as high as 310! Average id say is 230 or so

Sounds similar to what im getting

TRmachwon · 01-22-2012, 01:20 AM

Depends on how/where you drive. I drive mixed highway/city having fun every now an then and average around 18MPG. If you're driving mostly city I wouldn't be surprised by 15, especially with the auto.

japan4racing · 01-22-2012, 01:22 AM

Ive got bolt ons and 4.10's and see mostly in town driving....I average 19mpg

SHAKERRR · 01-22-2012, 01:24 AM

I'm seeing 22-25mpg with my set up. I also don't romp on the car all the time and I do mostly highway miles when I take it out.

liv2roc · 01-22-2012, 05:39 AM

mines a 5 speed with 81k miles mostly stock, I drive 45 miles a day round trip though a small town and back roads and get 26 mpg.

cruzmach1 · 01-22-2012, 07:35 AM

I wish I was getting what you guys are. I'm seeing about 15 mpg mostly city. And I always keep up the maintance.

ramair · 01-22-2012, 10:01 AM

Driving styles are so variable & they really affect MPG...hard to say but take her out on a nice long freeway trip & use cruise set around 70mph & see what you get. Our 5 spd can vary from 14 to 29mpg depending on what we are doing! They are so much fun to drive aggressively that it is hard to keep out of the throttle & drive for MPG's! Still have the stock 3:55's?

jayslx1 · 01-31-2012, 12:25 PM

Mine is also an auto and in the city with my few mods I can only get around 16-17mpg. I imagine with 4.10's it might get better (city)

73mach03 · 01-31-2012, 03:56 PM

I'm probably getting around 17 mpg with strictly city type driving. I have gotten as high as 19-20, but I've given up trying to get a few more miles per gallon. Too much fun to use the power when I can. I am getting at least as good (and usually better) mileage than the 03 V6 auto Mustang that I traded in on the Mach 1.

ModularMach1 · 01-31-2012, 04:33 PM

My car has a few bolt ons (5 speed) and i average 210-220 miles a tank with mostly city/highway driving. I know since all gas is atleast e10/15 ( i can't find 100% gas anywhere around here) my mileage has went down. When i bought my car i easily got 250+ with just driving around. I have gotten 28 on the interstate running 70-75.

Bad Religion · 01-31-2012, 05:31 PM

I get a consistent 285-300 per tank. Drop in filter, OR pipe, and catback only, tires at 32 PSI. Going to put the factory H pipe back on, SCT Tune, air up the tires a bit and see if I cant get 300-330. I do frequent highway driving.

First, Welcome! This is the section for Welcoming new owners. Questions, should be put in the appropriate section.

YOu should do a Search on MPG or Gas Mileage, it's been discussed MANY times, and start a new thread for discussion on the subject or just reply to an existing thread.

City, Never check it. Highway, around 25-28mpg. a few mods (CAI intake, catted H-PIpe, magnaflow mufflers, Iridium plugs and Amsoil full synthetic).

Thx.

AzureMach1auto · 02-14-2012, 06:51 PM

My automatic is all stock and I'm getting 22mpg. That is driving 55mph and never stopping for traffic. I have a great 30 mile each way commute through farm country.

I have gotten 17mpg avg/tank when I drove around town a lot and had to sit at lights. Automatic trans seems to really affect these cars compared to the stick Machs.

04comporgmach1 · 02-20-2012, 06:30 PM

I average 16-18 mpg city and 26-30mpg highway if that helps at all.
