Just filled my Armada tank for the second time (still running in), wow this thing drinks juice. First tankfull got me 13.5 mpg second fill up 10 mpg, is this normal? I have been driving it like a granny, not using more than 3000rpm and only light throttle most of the time, plus the odd 3/4 throttle burst. I would hate to find out what it does if I drove it like I had stolen it?
1. What model is your Armada? The SE (without the towing package) has a 2.94 rear axle ratio - perfect for saving fuel.
If you bought any SE with the towing package, the SE Offroad or the LE, you're stuck with a 3.36 rear end - and poorer fuel economy.
2. I'm getting 16-18MPG with my Armada - the cheapest SE I could find. I opted for the most economical rear axle ratio.
3. Don't be afraid of using plenty of throttle for getting up into top gear on the open road or passing. Sometimes you waste more fuel by wasting time in the lower gears. On the other hand, don't make quick standing starts - that's a surefire way of wasting fuel.
4. Don't drive for long periods at constant speeds (and rpms) during the break in period. If you have to make a long trip, try two lane secondaries instead of an interstate slog.
One other thing, the suspension feels very soft. Hit a dip on the highway and it wallows about (front to back), feels like it is running on springs with no damping (very bouncy like an old Yank tank), does anyone else suffer this? The Yukon SLT auto ride I just sold was a far better handler and much better comfort (plus I averaged 18mpg)
My Armada is very stiff riding - but the payoff is tremendous handling and roll resistance for an SUV. This big Nissan accelerates and corners like a Porsche Cayenne S and hauls like a 3/4 ton Suburban. Has Nissan made suspension specification changes for your market? If you are an overseas buyer, I'd have to wonder if the suspension of your vehicle was damaged in shiping from the United States? Sometimes vehicles are "dropped" during shipping by third party transport companies. It happens.
I know GM SUVs pretty well, and I would accuse any Tahoe/Yukon/Escalade of a floaty, poorly controled ride and clumsy handling.
As far as the 18mpg you registered with your Yukon, that sort of figure is plausable, if only because the smaller engined GM products fall far short of the Armada in performance. The only truly comparable drivetrain is the 6.0 liter in the Escalade and Denali - and you can expect horrific fuel economy with that beast - despite performance that still trails the Armada.
