Hi all,
I am new to forum and to G35. Have a question: G35xS 2008, 000700 mi ODT, City cycle only, cannot get more then 9.8 MPG or 1 full tank-GRADE SUPER only (17-18 gallons) for 160mi only. How I drive?? – Aggressively and gently. Finally the question: Is this normal range? Thank you.

 

What... are you saying less than 10 mpg? that's stupid, take it to the dealer.

 

there's something seriously wrong with your mileage calculator or car.

Most people average about 18mpg in mixed driving.

 

In city driving only, with lots of stop and go plus heavy acceleration, and M mode only including more than usual use of lower gears, I average around 14. 9.8 would require something like WOT from every stop...

Think there's a problem.

 

yea, i use my paddles more than I should, am always in DS otherwise, drive on highway at 85 to 90 and drive fairly aggressively with the rpms higher than necessary and I bang out a consistent 19mpg

 

I have a 6mt and get about 300 miles per tank. my driving is about 40% race and 60% calm

 

I got about 18.2 - 19.2 with hwy/ city 60/40 and spirited driving with coasting when at speed.....

I defiantly agree with you, something wrong. And my ride almost as yours, acceleration, lots of stop, 99% city drive and my average 9.8. What exactly dealer can offer? And also my previous car was Maxima 05 and my average was with the same drive train -12.5

 

Could be a lot of things, although most of them would also cause other problems (ECM problem, injector problem, etc.). Also, check your mileage using the actual gas tank consumption (in other words, fill up completely, set your trip meter. Next time you fill up, divide miles driven by gallons pumped). Could be something as simple as something wrong with the computation in your G.

However, if you only got 12.5 in your Maxima (I had an '03 Maxima, and got 16 - 17), sound like you're creating part of the mileage problem (take that as a compliment, you obviously bought the car to drive hard).

But 9.8 is way too low, my wife's Sequoia gets 14 even with me driving it...

 

are you sure its not your right foot thats causing the problem

If you only avg 12.8 in a maxima it sounds like you are driving your cars pretty hard which isnt a bad thing. Driving like a grandma, i only achieved 19mpg and now I drive alot faster and i still get around 15MPG.

 

wow! i thought i drove my car hard but 9.8mpg you take the cake! My car when i first got it and i drove it fairly easy i was getting 16.7mpg consistantly. Now it has 13k on it and i beat the living crap out of it and get 20.4mpg consistantly.... I gun it off of every stop too... Reset your ecu and then try it again. Maybe its running rich. After the break in period you should get better mileage.

 

I agree with the others your mileage should be better than that. I would complain to the dealer.

 

700 miles? Have you ever heard of a break-in period? DO NOT DRIVE YOUR CAR HARD FOR THE FIRST 1000 miles.


MPG should improve after a couple thousand miles.

 

don't worry about that.
it's the engine computer that calculates how many miles you can go according to the previous tank fill. mine read 220miles as its range when i first got the car.

now after about one month of ownership with three tank fills, mine reads 340miles+ on the estimate. the best i got was 365miles
that's with careful driving ofcourse

 

Thx Darkstar752 for the reply.
Yes i heard about break-in and i drive for now more intelligent. Also I live in Brooklyn and my ride takes me true the 25 local signal lights. I will post my MPG after a couple thousand miles. Thx for the hope.
