I guess I'm lucky, but I get around 27-27.5 MPG. 90% highway. 65 mile one-way to work, hilly... with a few runs of 100 mph + but most of the time 65-75 mph.

I have noticed a slight increase with Mobil 1 oil and Mobil 1 gear oil in the front and rear diff.

2013 X Sedan 7 AT.

 

I check my fuel economy display last week and saw that I was only getting 11 MPG. Decided to clean my MAF Sensors yesterday morning. I Haven't cleaned them since I purchased this car 6 years ago. Drove around the city mostly local. When I got back home... this is what i saw in the fuel economy display.

 

21 no matter how I drive on completely stock xS sedan

 

I drive about 80% city and 20% highway, roughly. I typically average about 330 - 345 miles on my tank. The G has potential to produce good numbers. Last time I did some highway miles, I got about 115 miles on a quarter tank. Does anyone know what the difference is between the fuel information on the dash versus center stack screen? I noticed they are not in sync. I am guessing the fuel info on center stack works off from when the vehicle was last shut off (so current trip), then info on the dash works off lifetime of the tank (when you reset when you fill up tank). Any info will help

 

2013 7at. I get 21-22 no matter how I drive. I can get close to 25 if 100% highway. Usually I drive pretty close to 50/50. When I had r2c intakes and muffler delete my mpg were still identical. If I drive the car like I want I get around 21. If I baby the heck out of it I get about 22. Not worth babying it lol

 

I've got a 2010 g37xS and I get around 400kms a tank, thats approx 250 miles maxed out beyond empty!

ughh.. anyone wanna chime in on whether thats good or bad?

Car is bone stock, medium foot, 91 gas, up to date with maintenance, do about 80/20 city driving. I am mainly in the city.. I've got all seasons tires yokahoma tires on brand new

 

I have a stock 2012 G37X sedan and get 14-15 mpg, city driving mostly. It also doesn't seem to matter how I drive. Tire pressure is 33 psi and I feed her 93 octane.

 

Those are some pretty low numbers, like V8/V10 territory lol. Even for city driving. I do about 60/40 city/highway and I average around 20-21 mpg.

 

At first, I thought that you meant 400 miles, which is more than reasonable at 20mpg. But if we're talking about km, that's horrendous. Are you idling in traffic for hours at a time?

 

I worry what mine will be, I probably drive around 80/20 highway/city. The odometer wasn't cleared when they fueled it up. I think it had 25 miles on it. I hope to get over 300 consistantly, but i usually don't get a full tank. I tend to get 3/4, to have less weight in the car. Being that it is winter, I don't need the a/c. I just got the car, unfortunately it didn't have tinted windows. I think one of the items keeping mileage low is the rpms on the freeway. I was surprised to see 2500 at 80, that is near what I had with my BMW and it had a 4spd auto. I thought I might be running in 5th gear.

 

damn, y'all are lucky. i do about 60 city and 40 freeway maybe... and if im lucky i can get 20 mpg

 

I'm getting about 20 miles per gallon. I drive in heavy traffic 5 days a week.

 

I did an overnight snowboarding trip from Jersey City, NJ to Stratton, VT. I was carrying 4 snowboards on a Thule Universal Pull Top carrier and Aerobars. I got about 21 MPG highway, down from 26 MPG highway. I didn't expect the snowboard rack to effect my MPG that much. I ordered an Inno Shadow cargo box, hoping that it would be more fuel efficient. I'll let you guys know how the MPG is with the cargo box.

 

Sitting at a solid 20l/100km, or 12mpg right now, temperatures have been into the low -20's, with windchill into the -35 range. I've had a bunch of short drives lately which is completely killing any chance of decent mileage with these temps. Gotta love the sounds the car makes when it's this cold.

 

Fueled up just outside of chicago (rockford) and drove back trying to keep it at 65 or under. This pic was taken after driving ~55 miles. Impressive, even in the middle of winter (low 30's here today).
