Re: Ford Edge Poor Gas Mileage
I still think the ecoboost engines are a mixed bag, in the sense that Ford is trying to improve their CAFE numbers, when the real world numbers fail to come close.
Stay away from sales guys. You bought it - it's yours. Sales guys stop caring after that.
Some Ecoboost engines require premium fuel (91 octane), but in some cases can be run on regular with less power and torque. I suggest trying a higher octane if you're not already as it might improve your mileage. If it fails to improve your current mileage, then something is knowingly wrong. Be it with the engine management software, or the knock sensors not doing their job to compensate for running regular fuel in an engine with boost.
Important factors for anything with a turbo or supercharger, is that anything over 30% maximum power will eat into mileage. With the EB engines, staying under 2200rpm will net you the best mileage. Accelerating over 2500rpm will worsen mileage as most boost is built up, thus eating more fuel.
Did the dealer examine the vehicle? It could be something as silly as a stuck/dragging caliper. As it is uncommon on such a new vehicle, don't necessarily rule it out. In some cases it makes no noise. If you accelerate into top gear by 50mph and notice a significant loss of speed, then the drive train should be inspected.
As catskinner mentioned, it might be wise to contact Ford directly and see what they have to say. 3K miles, or 5K kms is plenty of break in time. Fords recommendation of 18K might seem steep, but similar fine print applies to oil consumption and the one year comprehensive maintenance (if applicable), etc.
Depending on your geographical location, weather, altitude, tire pressure, weight in the vehicle, etc, all play a factor with fuel economy, or lack there of.
I would call Ford corporate, and while you wait for a response, bug the dealer service manager and keep track of all fuel receipts, mileage, and if you have an on board fuel economy readout, take note of that as well as hand calculating the fill ups on every receipt.
