I'm averaging around 29 or 30 in my ss/sc if I don't drive it hard

duh... I put LNF instead of LSJ.... I'm getting 25-30, unless I can't control my foot which happens from time to time... then I get 24ish :twothumbs
at the race track I get 6 mpg :lol::lol:
auto-Xing I get about 8 mpg

I am amazed at the power and economy combination, truly a great motor :twothumbs

I average about 23- 25 depending on my right foot. My highway gets about 35!

2.4L auto here, If Im not paying attention and just driving hard with traffic I get 27 or 28. If I make an effort to drive easy and stick to it, not letting it shift past 2500 rpm, i can get 33-34. I drive 40 miles each way to work so it pays to take it easy on the gas pedal.

25~26 all city not trying

City stop and go HWY on the way to work and no traffic on the way (3am) home.
27.9 for the week.
2008 SS/TC

depends on my mood.

bad mood tanks: 29mpg
typical\good mood tanks: 31-33mpg

Reign, I voted for the 25-30 on the LSJ. Since I have a LE5 also could you edit the poll to reflect a vote for 25-30 on the 2.4 also?

last one i got 27...time before that 25...ha

im trying to conserve gas. ha

30 city
38-40 hwy
:)

18.5, i <3 boost

damn Bryan... did you add the Hybrid option:lol:

for me to get any MPG near that, I'd have to chop off half my foot

thats with cams, 60's, and my majik finers!

summer gas does wonders. as well as a crap load of part throttle timing.

My DIC says 30.x MPG most of the time, using the old school method I usually get anywhere from 26-28 MPG per tank. I do a lot of highway driving.

I'm going to move this here

30-35 in the Turbobalt.

That includes some romps up to 135

:D love this fucking car

LNF @ ~27mpg

mostly 75mph freeway & stop and go traffic (which actually raises the average)

in my LSJ I was getting almost 40 to the gallon on the highway

on avg. i hit low 30s when i drive normal, if i am being good then i have hit 38mpg but heavy foot driving nets me around 25-28mpg

you mean mph correct, I would love 75 mpg though

I guess week-to-week I put 30-35 on my LSJ. That's not really accurate because my driving is extremely varied. I'll go a few weeks on nothing but city driving and sit at 28mpg or I'll go a few weeks on nothing but highway driving and be sitting at 38mpg. So I averaged those to 33mpg.

I'm trying to baby the car though so that I can officially say I haven't stopped at a gas pump in a month :-). Should have ~415 miles on this tank of gas if I keep getting the same mileage.

err, yea, the 'g' and the 'h' are right next to each other on the keyboard ;)

Canadian Gallon Vs US Gallon MPG
 

It occurred to me that the higher mileage reported by Canadian Cobalt owners might be due to the larger volume of the Canadian gallon...

here's a cut and paste.. http://aquaweb.pair.com/forums/archi...cgi?read=41109

TOPIC: A "PRACTICAL" PROBLEM
When travelling, we are sometimes confronted with a unit that involves "gallons", and frequently this involves American gallons which are different from Canadian gallons. The problem, then, is what is the conversion from American to Canadian gallons and vice versa?

In Canada, if we use gallons at all, we use the British gallon which is defined in a logical way: 1 gallon of water weighs 10 pounds (not very metric, but logical at least). The American gallon is defined as 3.786 litres. There is probably a logical reason for the American gallon as well, but I am not aware of it. The problem is to convert from one to the other.

We can proceed by finding the mass of each gallon:

A Canadian gallon of water weighs 10 lb which is the same as 4.535 kg. The American gallon is equivalent to 3.786 litres, and since 1 litre of water weighs 1 kg, an American gallon of water weighs 3.786 kg. Obviously, the Canadian gallon is the larger.

The ratio is 1 gal(CAN) = 4.535 / 3.786 = 1.198 gal (US). Rounding this off to 3 significant figures, we find 1 gal(CAN) = 1.20 gal(US).

So bottom line, the Canadian gallon is almost FIVE US quarts while the US Gallon is FOUR US Quarts. OR another way is 4 Canadian Gallons is ALMOST 5 US Gallons. The result is that if the general Mile Per Gallon term is used Canadian Cobalts will get about 20 percent higher gas mileage than US Cobalts... maybe better.

A 33 MPG Cobalt with US Gallons would get about 40 MPG with Canadian Gallons....

But, does the DIC show us MP(US)G or MP(IMPERIAL)G ?

I suspect the former......7.2 litre/100km = 32.1 MP(US)G .... which agrees with DIC.
7.2 litre/100km = 38.4 MP(IMPERIAL)G

I would expect this is because we :ca: don't buy gas by the gallon anymore, we buy litres. No point having the DIC calculate MP(IMPERIAL)G for a market where there are no gallons anymore.

That said, I am averaging 34 - 35 MP(US)G on my 2.4 5 speed, 160 km (100 miles) a day, about 80% highway. Cruise at 110 - 115 k (70 or so mph), shift between 3000 and 3300 or so.....unless I'm in a hurry, or just want to hear it sing.

Some of the secondary highways I drive on are posted at 80 k (50 mph), if I actually stay that slow I can get close to 50.....but little old ladies in minivans pas me then so......I am happy enough with mid 30's :)

91 octane btw, have not noted any mileage gains over 87 but it pulls better / smoother from low (under 1500) revs.

I think i get horrible gas mileage. My DIC said 272 when i filled up. I got to fill up twice a week :thumbsdow. But here is my question. Is it better to drive at high rpms out of boost or low rpms in boost?
