So last night I had a 250km (155 mile) drive to make and there was little traffic, so I decided to try and get good mileage. Before when I attempted this I couldn't get anywhere near the sticker value for highway of 8.6L/100km (27.3 mpg?).

I drove roughly:
110km at 100km/h (68 miles at 62 mph)
110km at 75km/h (68 miles at 47 mph)
30km at 120km/h (19 miles at 75 mph)

A couple of stops at lights and stop signs, one flooring for several seconds to get on the highway. I managed to achieve 8.9L/100km (26.4 mpg?) for the whole trip.

I have put 135,000km (84,000 miles) on the Murano in the last 3.5 years.

Those 19 miles @ 75 MPH put a dent in the overall figure. I bet the overall MPG would have been closer to 26.8 or 26.9. I have found that the optimum speed for fuel efficiency is around 60 MPH on my MO, unfortunately I usually run around 70 - 75 MPH if conditions and traffic permit.

I think the 2003 was "rated" at 20MPG in the city.

Big deal. I never see better than about 17 in Suburban Driving.
Get about 24.2 or .3 @a steady 75MPH tho.
Premium Gas of course.

Like most, my mpg moved up with my mileage.
At about 10K it was finally broken in and I get about
16/23 without thinking about it.

Yes it did. But it was only for about 10 or 15 minutes.

70km/h is optimal speed, as you are at the lowest RPMs for the highest ratio.

The conversions I did were to US MPG, not Imperial MPG.

The suggested economy I have were for the 2003, which I have. Nissan has since revised the numbers towards slightly worse mileage.

I've read the mileage posts. It just surprised me because my average mileage long term (about 60% city) is 12.5L/100km (18.8 mpg).

With a little over 1000 miles on my Mo (ooh, 1K miles, now that's a lot! lol) I am averaging around 19.5 in mixed driving using 91 premium.

What is interesting is that when I am on the highway, I am usually doing 80, with the trip computer barely registering 20 mpg, so highway driving is not doing me any favors.

I have to say that I am pretty happy with my mileage so far. Our '03 V6 Passat averaged 19.8 over the 3 years we had it and our A4 3.0 (with CVT) averages around 22.5.

We are driving down to the Keys in a couple of weeks, so I should be able to see what kind of mileage I can get for a tank full of moderate highway driving, since you can't go very fast down there.
