are you serious! I'm out in merritt, barely ever doing more than 50km/h and I just filled up today and get 480kms? Is this right? My car has the Stage 2

 

Well my car is stock now when I drove my car from chicago to arizona I got 400miles to one gallon checked it as I filled up now this is going from 55 to 60 and from 60 to 70 as I drove thru the diffrent states but when I hit the 70mph I got 415 wich I was happy but this was from e85 that's all texas amarillo had it was either that or 83 octane at 4am all gas stations were close so I risked it to keep the octane up but engine was fine didn't knock or anything actually felt a bit faster lol but im not trying it again

 

I do alot of highway driving so my L/100km is around 7.2L and my fuel range hit 792km

 

Computer reset for mileage available 460miles We know this is incorrect since 60lb injectors Actual mpg was about 29mpg.

 

well 250motorsportz... i dunno. it's what i get. i really don't drive it hard at all. only stock at the moment... i usually have my tire from 35 to 40 psi... and ever so often i throw in an octane booster and/or injector cleaner... nothing really specail... use premium but i doubt that will make all that much of a difference.

 

Translation - short trips in town = poorer fuel economy.

Especially when you let that stage 2 strut it's stuff

Take her for a longish highway run, guessing you will see much better mileage

 

Use the instantaneous readout to find the sweetspot on the highway when you activate cruise control. That would be the absolute highest MPG you would get, which is unattainable since you will always have to stop somewhere and idle. The average calculation is useful for your fill ups but if you want to diagnose something or compare data, the instant readout is useful.

 

07 SS stage 2 STOCK=423mi Highway w one tank

Tires 35psi

cruise control set @ 59-60

A/C off

Driver plus 120Lbs cargo

 

This is my best. It took a lot of drafting behind large vehicles and a tail wind.
2007 G5 GT, 5-speed, stock.

 

well ive seen some outrageous readings on my mpg gauge but i doubt they were true. Thats on MY case, YOU were drafting, quite possible with that drag shadow....

 

well doing the math, the tank is 13 gallons if you can manage an average of 35 mpg at whatever speed(s) you are going you can get to 455 miles before a fill up. Now I brim mine every time I fill up so if I try can get almost an extra gallon of fuel in my filler neck. Which means 500 miles on a tank is possible

 

After i bought mine i seen what i could do completely stock no cruis control i reset it when i filled up driving to work and back around 100 miles round trip 55mph roads and going thru 3 or 4 towns that are 35mph i got it to read 540 on the range a couple of times... usually it's jus above 400 tho

 

non stock fuel injectors? dic goes to **** iirc. best way to calculate mpg is to keep a log of everytime you fill up. put in the mileage of the car and how many gallons you just filled up. then after about 10 or so fill ups and some simple math you'll see your true mileage. and i bet a lot of you will be surprised.

 

My 09 SS/TC can get 30-33 MPG instantaneous on the highway, and that's not for a split second but rather holding it at a constant speed for a few minutes.

In my average daily driving schedule, I get 25-26 MPG on average. By comparison, my 07 Mustang GT w/ TR-3650 manual gets 21-23 MPG in the same driving schedule (only about 25-27 MPG highway) and my 00 Crown Vic gets 17-19 MPG.

 

^^^^^^^^^^^^^^^^^
I totally agree with you on that . I jus don't care that much cuz i know it's getting way better then my GTO and GTP. My bank statement tells me that. LOL

 

Thats about what i get, but it tells me I get 34

Ill have to get it up to 80 drop it into neutral and turn the engine off and let it roll downhill and reset it I bet I get a WAY big number
