How many miles to the tank are you guys doing? I have a 2000 gt 5spd...
Wondering if your doing 200+ miles to a tank....

 

last I checked mine was getting around 18mpg's

 

I have a 2000 gt with a 5 speed,cai,pp,3.90 gears plenum,70 mm accufab tb and stock exhaust with the cats punched out and I get 380 if it's straight highway and anywhere from 280-320 with mixed city. Just city gets me 250. I also have a 91 octane sct tune uploaded into it. I have 75k on er. Runs like a champ. However if I really put my foot into it I can drop that to 200 in a hurry. After I put the gears in my city mileage improved and I didn't notice a highway mpg loss. I guess it takes less pedal pressure now to get to and maintain speed. I also use amsoil synthetic 2 stroke or torco 2 stroke oil as an upper cylinder lube. About 3-4 ounces per tank. Seem to help the offset of ethanol when I can't find a station with pure fuel.

 

1997 GT pretty much stock with a borla cat-back auto, 20mpg combined

2003 Cobra pulley, tune, catback, cold air kit 22mpg combined

I have a feeling that having six gears helps the mpgs quite a bit in the cobra. The gt is kinda a pig on gas for a 215hp car lol

 

on the hwy I'll get 24 mpg, so about 360 miles on a tank, city is 16-18, usually hovers right around 20mpg mixed

 

I have a scan gage and It usually shows 24-25 mpg average. I have reset it and got over 27 on a 300 mile trip (highway). Around town the worst i see is 22 (I am not a stoplight to stoplight ricer..I mean racer). I can usually hit 150+ miles at half a tank (indicated).The worst I ever got was 4 days of driving to Barber Motorsport Park and open tracking 30 min. each day....15 mpg.

 

How do you like that scanguage. I was thinking of buying one. Is it worth the cost and what do they cost

 

With just a K&N CAI and Borla Stinger cats, my '02 GT gets at least 20mpg from mixed hwy/city while under normal driving, but who drives 'normal'.

Tacbear, that is one sick ride ya got there! I've always loved the white wheels on white car combo

 

About 18 MPG on german Autobahn with an average speed between 80 and 90 mph... all stock with an 4 spd. automatic

 

I got it mounted in the car and
I mostly use it for Air Inlet Temp... but it does a lot more. I like having it and I think it was worth the price (I think they are about $169).

 

Good to know. Thank you

 

My 96 Cobra vert gets over 20 mixed city & highway.

 

Good god....I have a 3.9 2004 with Mach 1 wheels and tires K&N CAI and run full synthetic oil and I don't get over 21 mixed.

 

I have a 1994 Mustang 5.0 that has a gt-40p intake 70mm t/b and headers with open 2 1/2" exhaust, no egr, a/c, 5-speed, and custom tune. I usually get around 275-325 miles on a tank depending on how much I get into her.
