Fuel Consumption!
 

Hi everyone,

Just wondering what is the average fuel consumption you get in your 370z?

I have a 2010 7 Speed Auto Roadster.... and basically if I look at my fuel economy it is always around the 14 L/100 km. So I pump almost 65 Liters of gas to fill up and I am lucky to get 450 km out of it.

Most my driving is city - so is this considered normal?

One time I did mostly highway driving and I was able to keep it around 10 L / 100km.

But I dont even drive it too hard.... if I do some highway driving I can get an extra 100 km out of it max.... but just want to see what you all are getting out of your Z.

Also if you add an exhaust or intake - will that increase fuel economy or make it worse?

Thanks.

The only time I pay attention to the fuel in my Z, is just before I need to fill up again. I know I use more gas in the Z than I do in our other cars. I can also tell you that I will use more fuel after I install the turbo. :tup:

I to have a 2010 auto roadster, 99% city driving getting about 450-500km max out of a tank of gas. Only current mod is a Stillen G3 CAI.

I didn't see much of a difference in mileage with or without the CAI.

This Ugly American has no idea what all that metric crap means. :) Here in the US of A, I get 18-21 MPG in town (23-ish if I drive like I have some sense) and 27-29 highway.

I get bad gas mileage. I love my car. Gotta pay to play.

I've had as high as 830 km on a tank doing all highway driving at 90-100 kph.

LMAO. Agreed. With mixed hwy and city at or near the speed limit my 7at roadster runs 22-27. I don't think that's too bad for a performance car.

I stopped looking but honestly, last time I think the average was 14-15L, most city driving. I have a few mods and I am heavy on the gas most times.

For sure if you do a lot of highway you'll see it much better, but I wouldn't concern myself too much with that when driving a Z lol.

Some say an intake actually helps fuel economy but I truly forget.

averaging 21.6mpg over 2300mi of driving mixed local and highway. This is just information I pulled from the car's hud. The car itself only has 2300mi on it so I suppose it might change in the future. I think I remember people saying that mpg goes up after the first oil change/break in period?

my average is 21.6 mpg for 27000 hard driving miles...

'i drive it like a pissed off teenager' :)

I average 20 mpg using the car as a daily driver on a 58 mile round trip, most tollway. The 4.08:1 gears hurts a bit but it's mainly a right foot problem.

I'm pretty sure I get about 13.5 L/100 km with a mix of city and highway and no concern for the environment... lol

that sounds about right. it usually depends on how you drive.

Even with a lot of spirited driving the worst I'll be getting is 11.9L/100km. Mostly city but also a fair amount of hwy driving. When I first got the Z I tried to save gas as much as possible (but still have a lot of times when I'm heavy on gas..) and I avg'd 10.7L/100km. On almost all hwy I was still at around 10L/100km. 6MT, but I'm not often stuck in traffic so that might be a factor.. Pretty much all stock except for a CBE and minor suspension bits if that makes a difference at all. I find that it doesn't fluctuate enough for me to care about the way I drive so I never drive gas consciously anymore, so I'm usually at around 11.0L/100km ish. I've been shifting at 2k-2.5k for normal cruising speeds because it's loud at any rpm after that lol

The navi fuel monitor generally shows 12.5l/100kms and that's mostly light city and backroad driving (three seasons only). The Transport Canada fuel consumption numbers are pure fiction IMO.

Manual Tranmission - City L/100 km (mpg) 11.8 (24)
Manual Tranmission - Hwy L/100 km (mpg) 7.9 (36)
Automatic transmission - City L/100 km (mpg) 11.5 (25)
Automatic transmission - Hwy L/100 km (mpg) 7.8 (36)

PS. for those south of the border quoting miles per gallon, note that our gallon is bigger than yours so even non metric needs to be converted for this discussion :tup:
