2015 Nissan Murano: Fuel Update for August — A Busy Month But Only Small Gains
by Dan Frio, Automotive Editor on September 9, 2015
Our 2015 Nissan Murano has been a bit of a disappointment for its fuel efficiency performance. As Dan pointed out last month, we're beyond 10,000 miles and hopes are fading that we'll be able to effect any significant change in lifetime fuel economy for the remainder of the test. In August, we posted our best tank yet, but it was a minor victory that lacked long-term impact.
In August, we filled up 10 times and consumed 108 gallons of fuel. That alone made it a busy month, since we typically average six or seven fill-ups per month. The Murano's main gig last month was serving as a support vehicle for our Yugo on its run up to Monterey. Somewhere in that service, the Murano posted its best tank thus far in the long-term test: 26.7.
Admittedly, that's only an incremental gain on the previous best — 26.5 mpg — and it wasn't enough to budge the Murano's lifetime 22.0 combined MPG.
That said, those 10 tanks in August, taken in isolation, averaged 23.6 combined MPG. Now that's pretty respectable whispering distance to the official EPA number. And those were legitimate combined miles, leaning heavily highway, but with plenty of slow city cycles in among there as well.
So why hasn't more of the test gone this way and why aren't we closer to the EPA number? Not sure, only that it appears we're paying for the sins of earlier indiscretions and turning in too-frequent tanks of 16, 18 and 19 MPG.
Worst Fill MPG: 15.3
Best Fill MPG: 26.7
Average Lifetime MPG: 22.0
EPA MPG Rating: 24 combined (21 City/28 Highway)
Best Range: 401
Current Odometer: 13,133
