Live in Canada so my stats come out differently on fuel usage. My commute is 25 km starting with a 20 minutes stop and go to the highway, 15 minutes of pseudo high speeds then another 10 minutes in the city again. Car says it averages 9.5 litres per 100 kms but lolling in traffic easily doubles gas consumption. What interested me was the comment that ethanol free fuel increases gas mileage. Is that true? Any other opinions on this? I have the 2009 G37x and while I try to gently cruise in the city I sure like roaring my way through if the highway is clear (alas, not that often!)

I get 19-22. I can get maybe up to 25 on the interstate and maybe 28 if I do that supermiler stuff - but this car isn't made for that.
I pretty much found that I get close to that whether I drive it like I stole it or if I drive like its a station wagon.
Just drive the hell out of it and love it.

At the risk of this turning into another senseless regular versus premium debate, the owner’s manual does say premium fuel is required. Using regular can result in two things: performance will suffer a bit, and engine life can be compromised. As said before, this topic has been covered adnauseam.
But what I find interesting is why anyone driving an Infiniti would want to use regular fuel. If you do the math, premium fuel usually costs twenty cents more per gallon. If the typical driver drives 15,000 miles per year at an average of 20 mpg, that’s 750 gallons used at 20 cents more, or $150 dollars extra per year. I believe that most Infiniti owners can easily afford that.

Hey canucklehead, you live in Vancouver? I can barely make 14 l/100km with mine and my transit is 30km one way to work...
some of the commutes described here directly relate to the resulting poor economy, not as much driving habits. a 4 mile urban commute? a 12 minute city commute with lights? these are very short city commutes which are the worst possible scenario for fuel economy. the engine runs "rich" for the first few minutes, and just after engine and driveline fluids warm up the car would be shut off. so not only is the stop-n-go driving inefficient, so is the operating condition.
this reminds me of a buddy who sold his mazdaspeed3 and bought a g35X (5AT) so his g/f could drive it on occasion to her work. they lived downtown and she worked downtown (don't ask me why she even needed to drive in the first place). my buddy, who is from europe where fuel economy is a big deal, complained endlessly about the mileage. being a G fan at first i defended it, but then told him that having a 3.5L engine idling in traffic is obviously going to gulp fuel more than a little 4-cyl so what does he expect? leave the car at home for short city drives if mileage was such a concern - plus, parking is a pain downtown...
anyways, for those who have no choice but to use their cars for stop-n-go urban commutes, you need to be realistic about fuel economy numbers. try ethanol-free gasoline to see if that helps. it usually extends my range by 5-10%.
my 10 mile commute is 95% "city" driving with a bunch of lights and hills. i get 11.2L/100 which is ~20mpg (US gal). have been doing so for 4+ years with little change - except a small dip in winter to account for running accessories. i can live with that mileage based on my commute and the fact that this is a heavy-ish sport sedan with 330hp.

However, the other addition about being able to afford the gas...you might be right. BUT, just you can afford it doesn't mean you necessarily want or need to spend that. I mean I am not going to get "cheap" gas but I cant know someone else for wanting to save that little extra

Do you live on an oil well?
Since purchase I've used 2035 gallons of regular 87 octane thru September 2014. At a conservative $.30/gallon savings that comes to $611.00 savings.
On my previous 06 G35 that was traded in at 171796 miles I used 7170 gallons of 87 octane (except for a 1 month test of 91 and 93 octane) at a conservative $.30/gal savings comes to $2151.00 for a total savings of $2762.00.
I'd rather have the savings in my pocket.
The only reason premium is recommended so as to meet Infiniti truth in advertising.
Does it really matter if the engine has 340 hp or 320 or whatever?
Not to me!
It gets me to work and back and to an occasional trip to Florida and back to New Jersey

Huh! $.20?

Similar to 7 11 or Quick Trip
The low gas prices are subsidized by the food prices sold inside.
Very clean rest rooms, no fee ATM's for Citibank customers and they are open 24/7
Current regular price today is $2.75
Lowest regular cash price today is $2.71 at Raceway

like i said, mileage is affected largely by the commute conditions - as well as driving habits of course. if you spend a ton of time idling in traffic or at lights, or do a lot of really short trips, you will see poor fuel economy. buy a hybrid or a car with auto shut-off if that is the case. or take transit or alternate forms of transport. i'm sure you are aware how much cash Mayor "moonbeam" Robertson has dumped into bike lanes! don't get me started...
