well i filled it this morning and my guess of 65 litres was a tad low..... it took 66.7 so just shy of 15 mpg on that tank.

after filling with regular 87 octane and resetting the mpg meter i was on the expressway and set the cruise at 60 mph at approx 1800 rpm. outside temperature was about 34 degrees today. went for about 50  miles without touching either brake or gas......all flat surface roads, no hills etc......managed to get 19.8 mpg on that part........ i would guess that is the absolute best the truck will do.........

if you guys tell me that is normal and the best i can expect then i guess thats it

actually i just looked at the nissan website; they quote 15 city/20 highway for a nismo 2WD automatic.........based on the new 2008 rating........

guess the fat lady just sang..........

glad to hear i am not alone

sorry to hear we are in the same boat.

part of your issue may be the new motor......but i can see it improving by more than about 10% after break in.

my last tank i got 14.5; with a tonneau and never anything in the back; 90% on a 4 lane highway.........29000 miles on it

love the truck except for this which will probably cause me to dump it

I have an '07 Crew Cab 4x4 standard transmission, and just checked my mileage on the highway.  Terrible!! 20 miles per Imperial gallon (16 miles per US gallon) on regular fuel.  That's the same as my old 1995 V8 F150, and one of the reasons I bought a new one was because of the fuel costs.  I don't see the point in using premium fuel unless the mileage increases by over 10%, because that's how much more it costs up here in Canada.  Gord

Another thought... I wonder whether the gas refining is getting crumbier??  I went on a trip into the US NW last summer and it seemed my mileage dropped off dramatically once I crossed the border.  Then came back when I got back to Canada, but only for one tank before it dropped off again and stayed there.
