I'm stuck on 20.3, and have been there for a while, I think pretty good for AWD. I drive 35 miles round trip every day to work on a highway that has some stops. I always buy Chevron or Exxon premium gas, but we have ethenol in our gas here.

My average MPG displayed on my dash behind the steering wheel is not synced with the info on the nav display. When I reset the nag display, the dash display does not change. Is there a way to sync both or to reset the one on the dash?

Also, the car is about 3 weeks old and I am getting <19 MPG in the city, not driving hard, and using premium. Was there any "breaking in" period to get closer to the 21 MPG that you saw

Since 13 April 2014, I have driven a total of 1617.4 miles on 84.714 gallons of 87 Octane gas for an overall average MPG of 19.1.


My city/driving mix is 82% City/18% Hwy -- and the city portion is in the Hills of Rancho Palos Verdes, CA. My wife takes our youngest daughter to school each morning, 2 miles each way, and the elevation change is 500 feet (7-10 % grades) -- a killer on MPG. For anyone who thinks that is bad for a Hybrid, my wife's previous car (a 2010 Buick Enclave AWD) was averaging ~13 MPG - so I am happy with my MPG.


I have also been closely tracking the difference between what the fuel pump shows I've burned MPG wise, and what the trip computer in my QX 60 shows. After 8 fill-ups, the trip computer in my QX60 shows I averaged 20.4 MPG over those same 1617.4 miles. In other words, my QX60 trip computer is over estimating my MPG by 1.3 MPG. I'm tracking my data on Fuelly. For anyone interest you can see the actual data for each fill-up at the link below. In the notes section I annotate what the small trip computer showed for that tank, then I reset it. I'm tracking my overall average MPG (the 19.1) on the large screen fuel economy page (you can set these two MPG meters separately).

Based on this data, I subtract 1.3 MPG from whatever the trip computer shows if I want to know my instantaneous MPG.

Been averaging about 20.1-20.2 in mostly city driving (85% city, 15% hwy). Took a 4hr long trip where I averaged about 22.7 in mostly highway driving (70% hwy, 30% cty)

I use Costco premium gas about 90% of the time... have about 2800 miles on the car... drive about 40 miles/day 6 days/week.

How long have you been using 88/base octane gas? Any impressions on the difference in drive feel and performance?
No issues with quality or performance, however I'm probably not getting the fully stated horsepower.

I really don't need all the potential power so I really don't feel it's a loss. *In addition, the motor has the ability to manage against the lower octane levels, by identifying pings in advance and compensating. *Those motors are made for worldwide use and very few countries actually have defined octane levels.*

Just finishing our first tank on our new 2014 QX60 AWD with all the bells and whistles. Averaging 13.8...PLEASE tell me this will get better! Checked with the service person, she thought it was because I wasn't used to how to drive the infiniti & was too lead-footed. I've asked my family and they don't think I'm a heavy footed driver either. Any other thoughts? Lovin the car but definitely not the mpg!:|

My Experience. I started out in April 2013 getting 15.7 mph on my first tank. Have everything but the package with large tires, cooled seats, and panoramic moon roof. Since then I have steadily improved.

My overall average is at 21.8 mph with the majority being city driving.

Hope yours will get better.

My first tank of gas yielded only 12.8 mph. However, over time it has steadily increased. I now have over 5000 miles on my QX60 AWD, and it is getting 20.3 mph. I use premium octane gas, and have not had it out on the highway for a road trip. This is city driving and I think it's great for this large and heavy of a vehicle.

I'm relieved to see those reports, I would be happy with 19-20. I'm keeping my fingers crossed!
Wow. You folks must be be feathering the accelerator to get those numbers.

I am logging 14-16 city and the best highway I hit was 19.5 on a 250 mile drive down from Boston to NY.

For comparison, I was getting 12 city / 20 highway in my previous G37 (very aggressive driving though) and am currently logging 36 city / 48 highway on my VW Passat TDI.

^ I almost consistently average 23 - 24 mpg. This includes rush hour driving and believe me I don't feather the accelerator.

I hit 26-28 mpg on the highway. (non-hybrid)

I use premium gas. I live in Calgary, AB which has an elevation of ~3500ft above sea level - which I think has a negative impact on fuel economy... or positive... haha not sure.

I am looking at Fuelly - for JX/QX/Pathfinder - and your numbers seem way out of line from what is being reported there. The meat of the distribution is around 17-18 and that is where my car is coming in with mixed driving.

Could it be units? If you are converting from km/l then you need to multiply by 2.38

^ I just used the google converter and put in my L/100km. I have verified the numbers and they are correct.

The car's computer report 9.0 - 9.5 L / 100 km consistently. (which is incidentally better than my M35 at 12.0 L / 100km.)

However, my average real world consumption (calculated at the pump) was 10.0 L / 100km last time and is within 0.5 of that number each time. (10.0 L / 100km = 23.5 mpg)

On my last highway trip which was 150km each way (93 miles), I average 9.0 L / 100 km which equals 26.xx mpg
