Info on the Gen 3 price. I have a buddy that is looking

 

Also to note.
I've done 2 tanks with 87 octane driving in DSA mode the entire time and having some fun with the throttle - 30% granny driving
Avg is 23.5

With 91, I had to grandma drive it in D mode about 60% to get 23.5

 

21-23mpg
90% highway 10% city
I Commute 30-100 miles a day for work.
i mostly drive in DS and i have a heavy foot
lol

 

After 21k miles, overall mileage is 20.6 with mostly suburban driving in D mode with DSC on. It's tough to find times when I can let the rear hang out.

 

I stay at or around 18.3-18.7, granted I work about 5 miles from my home and I drive 90% city and maybe 10% highway. DS about 95% of the time witha heavy foot

 

I have to coupe model but figured mileage should be around the same. I went on a 160 mile round trip to Dorney Park and averaged 24.2 MPG according to computer. I'm surprised I got that I was doing 80-90 MPH the whole way. I'm stock except for Hypertech but will be putting in a CAI soon. Usually though I'm getting 21.2 MPG overall in my highway and city mix.

 

With my new Expensive as hell PSS tires, I think my driving will become a LOT more conservative. I'm estimating I'll be getting back to around 24MPG Highway and 19 City.

 

20 mpg going to work (70% city driving), and 29 mpg on highway at 75 mph in average. Octane gas 91 always from Costco.
I notice a difference of almost 1.5 liter (0.4 US gallon) in average consumption when considering my formers G37x (dont ask me why its a long story ...) one model 2009 and one 2010.
Now I have an 2013XS and it's going remarkably well (the tranny, the consumption, everything).
I have 12500 miles with it and the mpg diminished around 5-6000 miles. See that on all three G37x.
Overall I have a solid 22.5 mpg and I'm pretty happy with it.

 

Did a round trip up to Columbus, OH and averaged 27 mpg running between 70-75 mph.

During a normal week I average 23 mph 80% highway, but on my commute to work I usually run into the beginning of rush hour traffic, so it kills my mileage a bit. This tank I tried to keep a light foot in the gas and was averaging 26 mpg, but was quickly bored after a half a tank. I enjoy on ramps a little too much.

 

I'm typically in the mid 18s no matter how I drive, I do drive very fast though

 

There are now 81 Infiniti G37 Sedans with reported gas mileage parked at Fuelly. Thanks to everyone contributing useful data there for comparison and analysis! The distribution is interesting, and mine is at the upper end since it is driven mostly on the highway (FWIW, I have been including average speed in the notes).

 

I can relate 100%. My G37x was purchased on Monday, and I've been driving it rather conservatively just so I can see how many MPG I can squeeze out of it if I need to. It's boring, but I've told myself that I'm going to do it for the first tank. I do accelerate heavy at least once a day to get my fix, but most all other driving is done less than 3000 RPM.

On my second tank however, I'll drive it normally. This means, anytime I am first at the light, there will be like 10 car lengths between me and the second driver within several seconds.

I'm also not 100% sure what grade of gasoline I have in there now...as I bought it used. So my second tank will be premium, and will happen when there's at most 4-5 gallons left in the tank.

A quick question...is this sorta like a Maxima (previous car) where the fuel pump is kept cool by the gas in the tank? Is it submerged? I recall reading that you should NEVER run a Maxima all the way to empty as it can damage the fuel pump.

I'll try to run it until it says only 20 miles to empty, then fill up with 93 octane.

 

 

My g37 says 0 miles to empty when the tank is still half full... the car even stalls after a while, and when I go to the pump, only 12 gallons in.

 

I am getting 23.5 mpg-mostly highway to work-no air conditioner-average speed 65 mph.
steady driving with minimal acceleration and passing.
