Im just about through my first tank, and I only got about 17 MPG with some highway and soem city, not getting on it at all....

What kind of mileage are you getting and how many miles are on your car, i think mine just needs to be broken in, im only at 150 miles....

We just went over 1,000 miles. 16 miles one way to work, mostly highway. Getting over 27 MPG. Display shows 28.1 MPG.

My g6 is currently at 1100 miles but I reset my fuel econ meter at 800. For that first 800, my meter read somewhere between 22-23 mpg. The vast majority of that was in town driving with speeds 35 mph and lower. I reset the meter at 800 miles because I was going on a 150 mile trip of highway driving and wanted to see what I would get on the hwy. For that trip the meter read just below 32 mpg.

Mine varies all the time, it's been all the way up to 25 and all the way down to 19.8 which is what it's at right now.

I average about 19 in the city. On my 200+ mile highway treks I have gotten about 33 every time. These are according to the computer. I would say the actual values are somewhat lower. Over all I'm pleased with the fuel mileage, it is improved over my Grand Am GT.

Anyone notice the gas gauge is kinda strange when you are driving hard? Like its 'estimating' your fuel level?

05G6GTstanger

Yea, when im Driving the gas gauge is always lower than when i put it in park, it really shifts around a lot, I think the fuel sensors arent too great.

GM's have always had a "floating" fuel gauge.

if i drive like a grandpa my fuel gauge will read pretty accurate but as soon as i slam the pedal down the gas guage will drop a couple miles.

Im used to floating gauges (my Z would slam you around in the seat and easily exert ~1G when pressed, parking on a hill, stopping hard, etc.. I know how it is 'normally').. this is much different. Its almost like its 'estimating' how much fuel you have??? Hard to explain.

I have the exact same car as the original poster - a 2005 G6 GT - and I have consistently gotten 21 mpg in a mixture of city and highway driving. Could be better, but I suppose it could also be worse.

I have a new 2008 G6 convertible (love the car!) with the 3.9 HO. I have 520 miles on it, and I'm getting 19 MPG in town - I'm ecstatic about 19 MPG because the sticker said 15 MPG in town.

While I don't really hot rod the car, I don't drive like a grandma either (I do drive conservative, though, most of the time).

When you folks post your MPG, please try to include engine size, so we can make better comparisons.

Thanks, and have a great 4th!!

30-34 MPG Hwy, 3.5 ltr Sedan.

I got as high as 35.7 mpg on the highway today at about 65-70 mph, 3.5L V6 (18k miles) Sedan.

I filled up the tank, reset the mpg on the radio display and hit the highway without any stops. After about 25 miles I was still getting a steady 35.7. I'll be driving down to PA tomorrow (mixed city/highway and hills), I'll post what I get.

g6_convertible
07-05-2008, 03:01 PM
WOW! 35.7 for a 3.5 by GUNIA is awesome. I drove about 25 straight highway miles after a fill up today, and got 25 MPG from my 3.9.

BTW, I have the 4 speed auto. I would assume that the 6 speed auto would do even better, but GM decided not to do that to keep the price of the convertible as something we common folks could afford.

Gunia
07-06-2008, 06:06 AM
Ok came back from my little trip. Total miles 342.5. The radio display reads 30.1 mpg. I calculated 28.1 mpg. There is a little discrepancy, could be the method I use, but even a worst case average of 28 mpg is great.

The trip was about 70% highway (60-70 mph), 30% local (30-45 mph, lots of traffic lights, hills, no bumper to bumper traffic).

I was also using a fuel system cleaner during this trip, but I doubt that had an effect on the mpg.

I didn't check the tire pressure, but I usually have it at 33-34 psi. Engine oil and air filter was changed recently.

I still get 28 mpg with mostly highway driving in my Impala (3.8L V6). I did get an average as high as 32 mpg. The 3.9 obviously has more power, but might also have more aggressive gearing. Also if you have larger rims, that adds additional weight to rotate...not to mention the additional weight of the convertible.

I have a 2005 G6 GT with the 3.5 liter V6 and I recently got 35 mpg on a highway roadtrip. That's the best mileage I've ever gotten in this car, it has 40k miles on it, and I was pretty happy with that. It was mostly flat high desert straightaways with some rolling hills and small mountains every once in a while.

In city driving I usually get 21 mpg on the dot. Which is not so great, but certainly could be worse.

For a v6, I'm pretty happy with it and any money I spent on a hybrid would not make a large enough difference to cover the initial cost of the new car. I had been thinking of upgrading to a Prius but I will probably drive this car into the ground and then buy a small electric or hybrid in 2012 when Toyota and Honda come out with their latest hybrid technologies.

There have been a number of electrical gremlins with the G6, and the dealer experience has not been positive. Which is why I will probably get a Honda next.

Had I not joined this forum I may have never heard these troubles you and others are having. I owned 2 Pontiacs before the G6 and have had great expereinces with them both. Now, with the G6 I am still in favor of Pontiacs cars. Maybe I'm just getting lucky. (?) Sure, there are some small issues that pop up but nothing a little TLC won't cure.
With that being said you need to know I also own a Mazda and it has its share of "little issues" too.
Good Luck!

I have a 07 with a 4 cyl and I get right around 28-33 mpg. I drive 70+ miles a day with some city driving thrown in. I have 21,000 miles on the car. I backed off the gas from 70 mph on the highway to 60 and the gas mileage jumped from 23.5- 25 mpg to that 30 mpg. It takes an extra 5 mins. to get to work in the morning but its worth it for the extra 6-7 mpg. I was filling up about every 4 days. If I do just highway miles I can get 33 mpg. would have never believed it made that big a difference.

09-23-2008, 07:55 AM
I calculate the gas mileage myself because I find the computer to be a little off. I have an 06 GTP (3.9L V6) and the best i've got so far was 24MPG mainly hwy driving on a 240 mi trip. On average I only get about 19MPG with city and hwy combined.. not too impressed.

I have an '08 4-cyl, with about 8500 miles on it. I get about 21-21.5 mph with mostly city driving. On the highway, normally it's 28-32. I always thought the city mileage was a little low for a 4-cyl.

Lampoon
11-10-2008, 08:38 AM
I always thought the city mileage was a little low for a 4-cyl.
I think that is due to the weight of the car. Personally I feel a 6 cyl should be standard. My 6 with an LX9 gets better gas milage than the 2.4 so why
would you want to put a 4 in a G6. I dont understand it.

So far this year, 11.6KM/100L or 20MPG combined, about 65% highway. That's tracked by fuel usage which is always worse than the average on the DIC.

there is a differnce between imperial and us gallons for canada, so anyone in canada has to convert to us gallons from litres, imperial mpg is usually 6-8 mpg more, which is what we go by, so example my 02 sunfire would do 41 us mpg but 48 imperial mpg.

2006 g6 gt s4 auto 36 mpg imperial or 31 us mpg

You have to realize that they measure MPG on a flat road. Put that same Chevy 350 up that same road and you'd probably be making 4 MPG. I get about 15 MPG going up big hills but going down the other side of the hills kinda even it out.

Hello all,

I am getting about 17 mpg around town with the 2.4 four. I am fairly easy on it (coasting up to lights and stop signs when I can, easy starts,etc.) and I live in an area with a lot of hills. I still think 17 mpg is a bit low. Any ideas or is that about all I can expect? Our 06 Accord returned about 19-20 mpg under the same conditions, although it was a 5 spd automatic. Car is stock with 13500 miles.

Thanks.

gapotts
01-20-2010, 05:18 PM
The V6 should get 17 MPG city not the V4 You should be getting 22. It's a little low. Make sure your tires are above 30 psi when cold. Obviously the hills are going to lower your MPG but not much you can do about that.

The Accord is rated at 21. So if that's the case you should be getting better than the 19 you got with your Accord.

Of course it depends on traffic and incline.

I can average around 32-34mpg on the highway, when it's flat.

In the city, average 22. This obviously fluctuates drastically based on traffic. I'm overall satisfied. I have over 41k on the 2006 GT Coupe, and I am still getting sticker or better mpg.

I usually get at least 24mpg city and as high as 43mpg hwy with the lx9 v6. Using all amsoil 5/30 100% synthetic and the low viscosity atf from them as well. I also have high flow intake, headers, catback, and an oil catch can off the pcv line. DO NOT RUN ETHANOL BLENDED FUELS IF YOU WANT MILEAGE (lower BTU output = crappy gas mileage and poor performance). BTW, I'm up in Canada and I know you guys are big on your corn alcohol.

I finally took my 09 gxp on a trip. On the way up to Maine almost 600 miles I averaged 29.8 mpg at an average speed of 65 mph. On the way home I averaged 29.2, forgot to look at average speed but I had heavy rain for about 3 hours. I can't complain as this is about the same or even a little better than my 00 GAGT i had previously.

I have the 3.5l v6, went 420 miles on the first tank which averages out to 26.25 mpg. the computer estimated my mpg at 29.6 with avg speed of 36 mph. I think the computer estimates more on how you are driving, meaning how fast you accelerate. I also used Ethos FR, and no im not endorsing or soilicitating the product. I will run the next tank without to see how the numbers compare.

I got 33.6 with my 2009 GT on a 62 mile trip through an area with some mild (and not so mild) hills to climb. I tried the same route at 67 and got 33.4 which makes me think the sweet spot for mileage in my car might be around 64 or 65. Running the same route at 80 yields 28.6...

With my typical city driving, I'm sitting at 17.5 if I keep my foot out of it and 15.8 if I have some fun.

I have an app to track my mileage since I bought the car. So far, 9,476 miles with 514.99 gallons burned since late December with an average of 18.91 MPG. I drive about 20% on the highway. Suck, as much fun as the G6 has been I really do wish I had bought that TDI.

07 G6V6 - I'm getting 23.3 on mine at the moment. The car has 98,000 miles on it so far. Knock on wood - the only issues I've had with it so far is the famous 'intermediate steering shaft', bad windshield wiper transmission, driver side wheel bearing and normal brake replacement. Passenger side wheel bearing is just starting to go. I'll have to replace that this weekend I think.

Between 16-25 mpg in the city (yes huge variance, but driving in the Bay Area and Chico is very different)

30-35.5 mpg at 55-65 mph. 26-31 mpg at 70-75 mph.

First a little background on me:
My first car was a 05 Doge Neon because of the price of the car Vs. the gas mileage.

I did my research and knew that it only had 132hp but I didn't think it would bother me. Long story short; IT DID!!!

That's when I recently got my current G6 GT. I said to myself: "Screw the gas mileage!!! I WANT POWER!!!!!(that I can afford)"

When I got the car, the MPG said 25 but now, after about 250Mi of my driving it says 14 MPG. It's a GM certified vehicle so I doubt there's anything mechanically wrong with it, plus it runs very quiet and smooth.

I love my G6 GT especially because of the suspension and tires!! That 219HP ain't bad either!! XD

Nothing. I'm going by the computer not actual mpg calculations. Reset the meter before you leave and check it when you arrive. When you're pulling an avg speed of 70-80 30 mpg is easy.

I'm also wondering if a performance exhaust and a CAI also is another determining factor as to why some of you guys get such good gas mileage. The restrictive stock airbox and restrictive stock exhaust must not help for mileage.

deathmage
10-05-2011, 01:32 PM
So I reset the mpg meter. and I'm now averaging about 33.9 on the highway doing 70 with cruise. It is a brand-new engine, not even 1000 miles on it yet. so maybe that helps.

Would a CAI and a GM Performance exhaust, the cat-back one, help even more with mileage?

penelopeTHEg6
10-05-2011, 06:05 PM
cai intake is only going to get you an extra 1 or 2 mpg.. its pretty much the same for the exhaust. if your lucky you could gain maybe 5 or 6 mpg all together

edit: the cai is going to help the engine breathe better tho.. cooler air is always better for the engine

The G6 is rated for 22 city and 30 hwy. I have a GTP with the 3.9 that is rated for the worst fuel efficiency and I can do that and better with my mods! It is mostly in the driver, but quality of fuel, tires, weather conditions, and several other things can also factor into the mpgs. So if you are not able to get your G6 to obtain these numbers you need to consider your driving style.

My g6 is currently at 1100 miles but I reset my fuel econ meter at 800. For that first 800, my meter read somewhere between 22-23 mpg. The vast majority of that was in town driving with speeds 35 mph and lower. I reset the meter at 800 miles because I was going on a 150 mile trip of highway driving and wanted to see what I would get on the hwy. For that trip the meter read just below 32 mpg.

Sorry if I sound stupid for not knowing how, but How did you reset your fuel econ meter?

Also just hit 100,000 miles getting 24 mixed right now. Just cleaned the throttle body a little and already brought my mpg up one mpg. I'm going to fully clean it somtime this week, to increase mpg, and also adding a K&K air filter so I'll let everyone know what the results are.

On another note I did spend one night racing with a bunch of people, Burned through a quarter tank, (from full to 3/4) When I topped it off I worked out I was averaging about 38 MPG. I was astonished because I burned pretty much that whole quarter tank while driving at WOT. haha

The size of the vehicle has alot to do with it aswell. Take a look at the mileage on any full size truck, the NA V6 version always has worse mileage than the NA V8 versions. Small engines have to work harder in bigger vehicles. As well, gearing and tire tread have a big impact.

well we are taking a long trip so I'll be sure to post everything when we reach the gas station. I reset everything every fill up (mpg, trip mileage, and average speed) maybe that's where the difference is? Even though I'm not sure it would matter.

Exactly! I think the G6 shouldn't have been offered with a 4cyl. But any 6cyl yes. It definitely needs more power (esp torque) to make proper use of the trans and to have enough power to get around comfortably, and therefore be efficient. Plus I have grippier tires which I'm sure brought it all down a bit. Hopefully once I build the motor a bit I'll see more MPG's. but it all depends on the way I tune I suppose. That's the trade-off I guess. Lots of power and fun, Or mpg. haha

I do the same, Every time I buy gas I always get a full tank, and I always clear every field in the INFO display. And I also divide my miles by how many gallons I buy. The math always works out differently than what my stereo says for Average MPG. And it's ALWAYS either +/- No consistency. But they're always close. Usually anywhere from 0.2-2.0 +/- mpg

My 06 GT does very well. It cruises decently and can pull itself up hills on the highway without worry of downshifting from overdrive. I can get 29-31mpg with it depending on speed. Southern Ontario roads don't have many rolling hills to use in the sake of fuel economy. No matter which vehicle I use the throttle is almost always on, even if I use cruise control.

Strictly city driving I'm lucky to see 18mpg as I use the auto stick and keep rpm in the 2500-4000rpm range.

On my old G6, which was a non-GT, I averaged about 24, but I also had a much shorter commute. My new commute is about 80/20 highway/town, the old one was about 50/50.

In my 2005 3.5L with a CRABs CAI, i average about 24.5 city and 55 combined. If im on an all highway trip i get about 27-28 mpg overall.

Getting less than 380kms out of a full tank of gas. 60% city driving and 30% highway driving.. anyone know why i have terrible gas mileage?

City driving is your culprit, especially if you have the V6. There are several factors that you have to consider such as:

Tire pressure (check at least once a week)
Speed
Acceleration to get up to speed & passing.
Weight in the vehicle
Air filter relatively clean - no rodent nests, etc
Fluids are changed regularly (12,000kms on cheap engine oil can increase engine friction which can lead to increased fuel use)
Heat - driving in traffic will make the cooling fans come on more often, heat is the main enemy of all engine components


Just to elaborate on tire pressure, some tiers for the G6 with higher speed ratings use upwards of 50psi, versus the stock 30-34psi setting. Running tires more than 5psi under their maximum will increase drag and can affect handling. I have V rated General UHP tires which are rated at 50psi, but I want a compromise with ride comfort and handling so I set them at 44psi. Most shops, after a service will lower them down to 30-32psi as per the door sticker, because the OEM Continental tires had a max of 35psi.

I don't recommend over inflating tires as it can prematurely bald the centre portion of the tread. In the hopes of better fuel economy (most of the time it will net 1-2mpg increase) is to take 35psi tires, and inflate them to 40psi, which in turn after a trip on the highway will warm up so they read 44psi. Handling then goes out the door, along with braking performance as the tread contact patch is limited. Just food for thought.

I have switched to Mid-Grade gas and went from 23 MPG to almost 27 MPG. I normally don't drive like granny either. Other than normal maintenance (new brake pads, etc.), that's the only thing I've changed recently.

Been driving my G6 for about 3 weeks on and off. A few days in the city and 10.7L/100 km in the city, and all highway is 8.5L/100km, then my DTE Says 705 km.

damn what sort of maintenance did you do to your car? my car reads 500km when i pump it with 87 but that thing is flimsy.. i only get around 350km a tank 60%city/40%highway which is terrible.. how much kms do you get out of a tank?

I drive too much of a combo of hwy and city to give good real #'s, but the average seems to be 22mpg, BUT I do notice that midgrade seems to give me the best mileage for my $.

Low end gas burns up too quick and premium is almost a waste of $. I try to pretty much stick with one grade of gas anyway to keep it running smooth.

Also, yes, as many said- tire pressure for sure and all other maintenance. The more you can drive highway only, the better your mileage is going to get for your $.

Well unfortunately I have yet to fill it, but I filled up on side of a highway and then did a night drive from 9:30-2:30 so it was cooler at night, otherwise it's how ever the dealer had it tuned up. I haven't pulled any plugs or anything yet to see what it looks like. I'll try and get a pic of the DIC when it shows this km's on there, maybe this Tuesday coming up.

Higher octane gas really makes a difference? I always read it didn't, and the owners manual says 87 octane so that's what I always use. I should try it.

I usually get about 23.5 to 25.5 mpg depending on how hot it is and how much the AC is on. I travel 50/50 highway/city usually. It's not bad considering my last car never got above 18mpg. Still I would like better. I hear the cold air intake helps.

After putting in the transmission cooler this weekend, took it out on a 12 hour drive as well. Got a whopping 7.7 L/100 kms on the flat part of the highway, 8.7 with a little more load and rolly mins and 9.8 going up steep hills. The total DTE by the end was 630 kms driven.

I've done nothing but pop in a K&N replacement air filter and used some Bosch fine wire iridium plugs. Haven't even done the throttle body clean yet either.
Maybe I got lucky and the previous owner(first owner) broke it in good and so now I'm reaping the benifits of it.
I don't drive it to work, its more of a pleasure vehicle so for now its like 90% highway and 10%in city/drive to work.

All G6s have a 16.0gal tank, or 60.5L. Factor in a ~8L reserve (when the low fuel light comes on) and 220kms on half a tank isn't that bad.

Its there to decrease the sound coming from the intake say at wide open throttle. It also acts as a baffle to stop water from getting in.

Its really just there to quiet things down.

Made that trip ALL in 1 tank of fuel going 1 way.
Going there my average according to the DIC, says between 7.5-8L/100 km, and on the way back (I don't ever see this happening) said DTE:860 km, but again, must be very rough estimate, otherwise on the way back was seeing 7-7.5L/100km. My receipts on fuel that I had got show me actualls of 8.78L/100Km, and on the way back 7.5L/100km.

I figured mine the old school way...fill it up, drive it and then fill it up and divided the gallons added to the miles driven.

My driving is about 70/30 city to highway and I averaged about 22.79 mpg in my 2007 pretty much stock 2.4L 4 door G-6 with automatic transmission that now has 89K on it. Its a second owner vehicle that I bought off a impound lot, so its not like I have owned it new and babied it all these years. The only mods to date are K&N Air Filter and I am currently driving with a check engine light for a catalytic converter code. Further more this is Texas and you better believe I am using the A/C!!! That's code for "its still hot here!". Just saying...

Im just about through my first tank, and I only got about 17 MPG with some highway and soem city, not getting on it at all....

What kind of mileage are you getting and how many miles are on your car, i think mine just needs to be broken in, im only at 150 miles....

I'm getting a steady 20-22 MPG around town (I mean on surface streets at rush hour 'cause the freeway is BAD) and on the freeway when it's stop and go or slow and go. I get a steady 29-33 MPG on the road.
In town I have NEVER EVER gone below 20 MPG.

We travel long distances every 2 months to either Salt Lake City UT at appx 750 mi one way, or Albuquerque NM appx 900 mi one way, and we only stop for gas and to pee.

Utah speed limits are USUALLY 75-80; AZ/NM around 70-75. I can tell you that I PUSH those suckers a tiny tad...

The MOST I ever got was 36.2 MPG in May 2012 on the way to Albuquerque, BUT I was following a U-haul with my daughter and going 55 MPH.

15.8 mostly city driving. 3.5L 07' v6....why the **** am i getting such bad gas?!?!?!?!?

Just had alignment done (tires are shotty but gas mpg has been same since they were new)

new battery put in, oil changes are done regularly. I had my wires and plugs replaced in 08 so they probably need changed (noticing my headlights dim sometimes when shifting into drive or using power windows)

my fuel filter hasnt been changed, and the car is at 110K miles, still drives like a dream. I havent changed the fuel filter because you must drop tank to get to it and my personal mechanic told me i have no reason to do it yet.

going to do a throttle body cleaning...but i cannot figure out WHY do i get such god awful gas?

I think the 3.5 epa estimated is 18 city, 28 highway.

what area are you in. I know up here in Illinois they recently changed over to the higher ethanol mix for the winter months, as they do every year, and my mpg went down with it.
You could just be experience the loss due to that.

What kind of mpg do you normally get?

I calculate the gas mileage myself because I find the computer to be a little off. I have an 06 GTP (3.9L V6) and the best i've got so far was 24MPG mainly hwy driving on a 240 mi trip. On average I only get about 19MPG with city and hwy combined.. not too impressed.
