offical fuel economy vs you
 

Hey guys

firstly, i love my car, puts a smile on my everytime. At first i didn't like the sound of it but now i wouldn't change it...

But there is one cause of pain... the fuel bill. In australia we have a department that gives cars an official fuel economy rating. For the 370z manual it's 10.5L per 100km.

every other car i've driven i've managed to beat the rating in fringe peak hour traffic (15 mins before mega peak hour traffic hits). With the 370z, i cannot beat the official rating?

anyone else having trouble beating the fuel rating?

side note: dad traded his R36 for a Q5 with 2L petrol turbo. I'd happily put that engine in the 370z... power/torque to fuel economy of that engine is insane.

The direct injection Audi motor is quite nice, but it is a turbo motor. So you get the econ advantage of a 4 banger, but the power of more displacement. Not a fair comparison. I get about 23-24 mpg (sorry--you need to convert) with the majority highway cruising. Maybe the agency is getting better? Are you using premium petrol? cheaper gas will impact economy.

Driving it in S'pore,i got 8.2km/L,mixture of highway/city driving,+ a few high revs pick-up.

do you mean 8.2L/100km?

must be a lot of coasting involved with that

Fuel economy issues
 

I have a 370Z touring coupe (6 speed, no sport package) and have accumulated approx. 9000 miles since I first took delivery in June of 2009.

Amazingly my machine gives me up to 30 mpg on a consistent basis, this includes both in town, highway and interstate driving.

I have been using Castrol Syntec full synthetic oil and sometimes use mid grade gas with no apparent side effects.

Needless to say this car is amazing to drive, a little road noise perhaps but a joy to cruise the mountains of Pennsylvania.

I've had the car for less than a month and driving conservatively under 4000RPMs (6 speed) in the City of Chicago is getting me 11.7mpg =(

Hey neighbor, I'm in Greensburg but I'm getting only slightly over 20mpg, mostly in-town, some open road, on my base automatic. I expect more after break-in is complete, though I obviously didn't buy the car for economy and that's not my priority. Nevertheless, 30 mpg is phenomenal! Good for you.

In my Cobalt (and then G5) the advertised MPG was 24-30 or something?

I averaged 26ish pretty consistently.

In my Z I seem to be steady at 21MPG.

I do 80% city-esque driving with the rest being highway. If I was incredibly gently and drove it like a Prius I'd imagine I could get to 24-25.

That will never happen though. :p

edit: also it's pretty sweet having a 380+ cruise distance.

i'm getting between 18.5-21mpg but i am a little heavy footed when it comes to driving. i'm sure if i took it a little easier,i could crank out more, but that's just not as fun. plus, im left with a lot of stop and go traffic in Dallas which kills the mileage. then there are moments when i need to pass slowpokes...

I've been driving mine for about a month in Los Angeles traffic.

I'm averaging 13.8 mpg with lots of stop-and-go and a bit of a heavy foot.

I didn't expect the mileage to be quite so poor...trying to ease up on the throttle a bit lately to see if it makes a big difference...

holy wow. that's low. even in real aggressive driving i've only managed to get it as low as 16.9. are you drag racing stoplight to stoplight? lol

@13.8, i'd expect a v8 under the hood. my friend's land rover averages about 11mpg...

I actually measure it in time, i.e. I get two weeks out of a tankful (I don't trust the MPG gauge in my Z). Then again, I live only 9.5 miles (15.30 kilometers) from work, so I don't put too many miles on my beaZt; she's a 2004 Touring Coupe and only has 25,595k on her. Greetings!

On the day that i picked up the car, my salesman gave me a full tank of gas. I went with him to fill it up. It's $50 USD. ($3.10 per gallon) and the tank was already 1/4 full.

I almost fainted. Gas money per month is the same as car payment for me.

According to my GasCubby app (iPhone) my max MPG is 22.04 with an average of 18.61. This is with 26 fill-ups and 8,143 miles. I average 48.76 miles per day and this puts me at 15 cents per mile.

This info does include my most recent weekend at the track where I averaged 9.85 MPG.

i just fill when empty. i dont care about mpg on this car or my G35C.

I average $80.00/month on gas expenses--I fill up every week; on average, $40.00, equivalent to about ½ a tank.

you fill up every week @40 bucks. but you spend $80/month? how many weeks do you have in your month :P

i spend about $35-40 a week, so, that's about $160 a month. in my old car, i'd spend about 30 a week tops, so not too much of a change.

No its is 8.2Km/L...comfirmed.

Ah ok you're doing 12.2 L per 100km.

ok makes sense.

I never worry about the MPG, especially in a Sport car. Just drive the car and enjoy it!

Yeah but it's my daily driver as well. The fuel economy thing wasn't a major issue, else i would have got the 1.8L turbo audi TT... but still i thought i'd be able to beat the offical rating and save some money.

My 370 (manual, touring, not sport) averages around 19 miles per g. I do mostly street, with minor highway or interstate. Highway i seen it range in the 22s, but thats me flying 95mph so i'm sure better gas mileage is possible. But like everyone else said, its a sports car so who cares.

I seem to average 18 mpg with regular driving, which for me is nothing but highway gridlock. Weekend fuel economy is in the lower 20s.

Highway mileage in this car is very good -- I can pull about 28mpg average on a highway trip that takes me through the mountains. I'm sure a flat run (say out to Chicago) would take it over 30.

370z touring 6 speed
 

After reading all the threads it appears I am doing something very much different than the rest, perhaps it is because I really don't have a heavy foot, or keep my tires inflated to 35psi and really do little in town driving, but the up to 30mpg highway I earlier stated is no exaggeration and not a computer number but a real world gas consumption calculation. I sometimes get less than 30 mpg but this is due to more in town driving.

I live in a small Pennsylvania town with little or no rush hour traffic to mention and this must help somewhat

My machine, weather permitting, is used primarily for highway cruising at 55-60 mph or an occasional interstate jaunt. I mostly try to cruise the winding state roads as they are a much more fun to drive.

rmhockman, cruising at 55-60 is the Z's sweet spot. Using the "real time" mileage monitor on the computer, I know my mpg rating is highest at 55-65mph, usually around 30mpg. its the stop and go traffic that really kills the mileage, so if there's a lot of city driving, you're going to get horrible mileage.

consider yourself lucky to have little traffic :)

I LOVE IT!!! :bowrofl: I am the same way its a sports car! my old mustang only got 12mpg on a good day! but then again it was a 400rwhp Bullitt until it was totaled :mad:

Anyways, I get on avg. 15-17 with my heavy in town foot and 25-30 on my hwy travels :tup:

I average 19-20 mpg. I have 6700 miles on her, purchased June 30, 2009.

I only fill the tank probably once a month given that I only drive on the weekends.

Sweet spot for mileage NOT for fun!......:tup:

I average around 17mpg...

Sweet spot for mileage NOT for fun!......:tup:

I average around 17mpg...(and I live in the country...)

You can check my exact stats on Fuelly.

My low is about 21 MPG, average 23 MPG, high is about 25 MPG.

hey i never said it was fun...:driving:

Mostly highway driving with a track day :happydance:

__Date___ | $/Gal_ | Gallons | Total $ | Odometer | _Station_ | MPG

04/04/2010 | 3.099 | 15.496 | $48.02 | __769___ | Shell_____ | 8.03 | <- Track day!

I average 18.5 mpg, mostly city driving. With 2800 miles on the odo, I expect that to gradually improve.

highway mileage on any small car even if pretty powerful is going to be fairly similar. the upper limit of my altima on highway (EPA rating) was 31, the Z is 28. I actually get 24 all around combined driving. the thing is, its easy to calculate highway fuel economy, but local/city driving, theres too many variables. one persons local driving could get much better fuel economy than anothers, just based on location, time etc, its not all about having heavy foot or a powerful car. i'm sure there are people who do worse in a honda fit local than some people do in their Z local, just depends where/when

average 21,5 mpg

I'm around 21mpg. I've seen as high as 26 and as low as 14.

Average 18.5mpg, sorta have a heavy foot on takeoff and love to gun it to merge into traffic.

24.9999 mpg average over a couple months. 90% highway. I am a gentle driver 98% of the time, a mad man the other 2%. That's very good for a car that can rip it up when you want it to.

I'm lucky to hit 16 mpg on a regular basis. I don't really care though. :)

Fuel economy? Tell that to my right foot :rolleyes:

Frankly, never looked at it or bothered with it. Car throws the signal "empty tank" and I fill it up and drive like this :driving: until the next fill up.

When my dad was in hospital (October 2008 for 25 days), I used to fill up EVERY 3 days! That's $55 dollars EVERY 3 days religiously :tup:
