So I went on a Cruise to enjoy the day Sunday. Some city and Hwy driving and I reset my Average before leaving.

So after a 20mile drive to get lunch, all back roads and just cruising I ended up with 21.9mpg once I got on the Freeway.

Notice the Mileage as the pics go. Got up to speed and set the Cruise control on 65mph. I got a ton of Thumbs up from people passing by checking out the SS.


On to the pics - You'll notice the MPG Average climb as the miles go up.

2,180miles - 21.9mpg

2,187 - 23.1MPG

2,192 - 23.5MPG

2,201 - 23.5MPG

2,204 - 23.7MPG

2,208 - 23.9MPG!!!

2,209 - 24MPG!!!! HOLY ****!

Getting off the Exit ramp the Final climb Peaked @ 24.2MPG!! 2,224miles on the Odometer.

I drove to visit my dad in Kentucky last Labor Day weekend, in the G8 GT with DOD, Roto-Fab and 93Octane tune I got 24mpg for the trip.

So if you can restrain yourself from WOT you can Economically drive the SS on long trips and Save $$ by getting pretty decent MPGs for a 450hp+ BEAST!

Drove in my Mother's G6 GXP 2 years ago to South Carolina to see my Niece Graduate @ Paris Island and become a Marine. Drove the G6 on Cruise control and we average 35mpg on the trip total with a Peak on the way down of almost 37mpg. Her car wasn't even rated that high on the window sticker for the 3.6l VVT

Keep you tires inflated properly and a good clean air filter and you'll be good. I will do this again when I visit Kentucky this summer. Hoping for 26+mpg or more on that trip.

@ 4mpg more than the SS was rated for @ 21mpg doing simple Math will show the savings.

19-20gal of fuel so lets say from Empty you put in 19gals to top it off.

4mpg better fuel economy for 19gallons of fuel = 76miles of travel

To travel 76miles it will take approximately 3 Gals of Fuel.

Let's say 93octane is $3.75/gal x3 = $11.25

If you are using the Freeway/Interstate and drive on Cruise control you can save a ton of money of the life of the car. $11.25 per tank will add up.

Just wanted to share. :whatdoyouthink:

Not necessarily the reason we developed the tune, but it's just another benefit of it

I got a little over 20 at 75 mph going home from Livernois and included stop and go traffic in Toledo and dyno runs too. I can live with 21mpg no more than we drive on road. I will try it at 65 some time driving sensible!

Better mpg is just BONUS on top of the increased fun factor!
May have to start thinking seriously about springing for the CAI & 91 tune. Beats the 17-18 mpg of my 5.3 Sierra at hwy speeds. The '07 SS Impala with 5.3 will only do about 25 mpg at the 75 & 80 limits we have in Texas now.

I'm averaging 13...nuff said

 

[AntsSS]

13mpg? That's crazy I literally floor my SS everywhere I go since new and average 16 mpg.

 

[037]

well...there's city mileage and then there's new york city mileage...my previous car was rated 18/28, and I was getting maybe 16 average.

All..Are we really concerned about fuel economy? Come On Now; Really? This is a family sedan with an LS3 motor pushing approx 420 hp stock..It's meant to be driven! For those that honestly worry about Fuel Economy there is another Chevy product call the "Chevy Volt" that maybe should be driven instead of the Chevy SS..LOL

 

[Maverick Man]

personally i would be more interested in seeing an average MPG rather then a reset on the odometer.

that's just me though.

personally i can say in my GTO i get 18.2 avg. but heck i can reset the odometer and take it for a 75 mile drive and say i get 25 but to me that's not really an average and you are not going to get that all the time. **** i can cost the thing in neutral and do hyper mileage like those MPG freaks and say i get 28mpg but really.... just looking for an avg mpg

 

[Maverick Man]

also happy to say that just today i hit 17mpg! now this is the AVG the car has been getting since the day i bought it. i have not reset anything. i just don't like to fool myself by resetting the trip.

You can always get your lifetime MPG average on the Onstar App, mine reads 14 lifetime with 1490 miles.

 

[Commodoreman2000]

I always like to try out the best way to get awesome mileage on highway trips but that's where the frugality ends.
The rest of the time If it needs fuel I fill

This is my Daily Driver. I sometimes take long trips. During those long road trips I am still taking my performance sedan, I just don't feel it necessary to drive like a fool on the freeway and conserve some $$ during those trips.

I'm not "worried" about anything. I was posting that the Roto-Fab & Livernois tune simply gives better MPG than the factory tune. :duel:

The Window sticker shows 14city and 21hwy. 17combined.

I simply reset the average for the cruising I planned on doing. My lifetime Average will never be accurate. Going to the track and driving my car like it is meant to be driven and having fun from time to time I will get less than 8mpg or so.

From the original post. :blink:

Getting better MPG with the tune and CAI may be true, but to Liquid's point, this Saturday I filled up and put on 120 highway miles, ranging in speed from 70-90 and I got home with the computer telling me I was averaging 23 MPG and mine is all stock. Lets get some miles on these suckers first before we start speculating. I'm sure without any tune I'll be getting better gas mileage when I get closer to the 10k mile mark, but as others have posted, I didn't buy this car to worry about gas and I do daily drive it.

 

[GXPaycheck]

After 4 sessions at VIR, mine showed 15mpg :biggrin:

 

[Tarnath]

You can always get your lifetime MPG average on the Onstar App, mine reads 14 lifetime with 1490 miles.

True, but the OnStar app rounds your MPG. so 14 could be 13.5 - 14.4.

 

[ChevySS]

The numbers provided in the estimated MPG are based on a standardized testing method. How Vehicles Are Tested

These numbers may vary but I assure you that the more you drive it, the closer you will get to the tested numbers. A short cruise drive is not a good indication of MPG performance.
On my way to work (1000' difference in elevation over 27miles), it's downhill and I get about 23mpg. On my way back from work, it's about 17-18 at 70mph both ways. So it will balance out. Not saying the tune didn't help because it probably did, but just saying keep driving it and let us know what you get.
