how do you find lifetime numbers?

Yes, please share how you got those, 08SGT1977.

23 MPG too! That's great. I get 14 MPG - all short trip driving.

[AstroDan]

Well... I was around 20ish pre-SC and "normal" driving; Now it's about 14! (Not "normal")

You guys in the Army too? Here's the GI proof instructions (ha ha!).

Go to the odometer and record the mileage. Select the info button until you get "Gallons used" and record the lower number (lifetime). Here's the tough part for us soldiers: divide the miles by gallons to get the lifetime MPG. Post it here for all to see. Let us know if you are supercharged/turbocharged etc.

Mine was 24 MPG but I have been running 20" wheels for a few weeks and it's getting colder.

I know it's about smiles per gallon as we bought these cars for their performance but thought it was amazing to get more than 20 MPG in a muscle car!

I reset Gallons Used after every fill-up. It usually differs from actual gallons injected into the tank by half a gallon in ten. That's a five percent optimistic figure by car computing. 24 mpg x .95 = 22.8 -- still good for a performance car.

My Lifetimes, by actual miles and actual gallons, and including a whole lot of autocross and drag-racing passes:

5-speed manual: 5775.1 / 270.113 = 21.38 (Last year's Terlingua trip, 2692.9 / 103.93 = 25.90)

Auto OD: 2455.3 / 133.731 = 18.36 (This year's Terlingua was about the same length and typically calculated at 21-25 MPG tank to tank; I logged all the miles and gallons, but haven't put them in the spreadsheet yet)

Thanks 08SGT1977. I didn't recall seeing the gallons used on my readout. I'll have to re-check that in the morning.

32,566 miles/2281.3 gallons = 14.3 MPG lifetime

It's sure been an expensive year, but I've enjoyed the hell out of it.

I know what you mean, Ken. It never gets old!

Thanks,

Never gets old is right! And compared to my 66, which averages 4 MPG, the SGT is like a Prius!

must be an '08 thing, my '07 doesn't have the lifetime numbers!

It doesn't show how many gallons of fuel your car has consumed over it's lifetime?
If it does, just do the math between that and your odometer reading.

Ken

[jmn444]

nope, there's no other gallons used other than the one that has been reset... i might look in the manual at some point, but since i've owned it i'm pretty sure i'm around 22 mpgs and that's having a good amount of fun in it, so I'm happy

[Dans07SGT]

Yeah mine reset also. Either that or I'm getting 56 mpg.
Last April was the last time I reset it and since then my average is 19.8 mpg. Quite a surprise considering how I drive. I'm happy with that.

Ken our mileage is close, I'm at 32,304.

Mine doesn't have lifetime numbers...maybe they removed it for fear drivers would look at it while driving and have a heartattack when they saw the amount.

That's okay though...I always wanted to get to know my local gas station attendant on a first name basis.

It looks like the GT/SC will give you around 15mpg in return for ~500 horsepower and 20+mpg bone stock.

[motorjock205]

Hmmmm, I tried to view lifetime gallons used on my 08, and all I get is current gallons used...I've tried Single and Dual display mode....I don't get it???

[08SGT1977]

hmm - maybe I should record a video and post it. I have the premium IUP. I wonder if the computer is different in the premiums??

It shows the total gallons for the trip and the lower number is for the lifetime of the vehicle. The other is just your total miles. You have to do the math.

I would be interested in your numbers Carl, I know you like to go 150mph on your way to church.

I've got premium IUP but I don't find this "lower number".....

Maybe you could post a video!

I have IUP in mine, but I'm like Ilmor, I don't see anything but one line of numbers and it gets reset when I fill her up every time...A video of how to get to it or written instructions might help...or a page reference in the manual...
