Fuel Consumption!

SIKHRYDE

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.

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.

MrSir

if you dyno tune the car after you get the intake maybe. For me with all stock components the best i have done is 9.3L/100km and that was on a drive from Toronto to Quebec City, So all highway pretty much. other than that stock i was able to get it at around 10.3-10.4L/100km. NOw that i have HFC, CBE, and CAIs its a different story. The CAIs made the biggest dent in the fuel consumption, i have the AEM ones and they do some black magic with the MAFs so my fuel consumption with 70-30 HWY-City is about 11.7L/100km. All city hits close to 15L/100km

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?

RandyD

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

Tickwomp

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
