The Nissan Armada is a full-size SUV that began production in 2004 and is available in both two-wheel and four-wheel drive models. In 2010, Nissan began producing a flex-fuel version of the Armada which is capable of running on E85, a corn-based fuel. No matter which specific version of an Armada you are driving, there are a variety of ways you can increase fuel efficiency to get more than the Environmental Protection Agency ratings assigned to your Armada.

Step 1

Change the air filter and spark plugs according to Nissan's suggested schedule. The air filter should be changed every 7,500 miles and the spark plugs every 60,000 miles. Dirty air filters and spark plugs will decrease fuel efficiency by preventing the fuel from burning at maximum efficiency.

Step 2

Reduce the aerodynamic drag on your Armada to increase your miles per gallon average. Only carry items on your Armada's roof rack when absolutely necessary. When traveling at highway speeds, drive with the windows rolled up, which will reduce drag on the vehicle.

Step 3

Check your tires weekly to make sure they are properly inflated. Statistics from the Department of Energy indicate that underinflated tires will reduce fuel efficiency on a vehicle by 3.3 percent.

Step 4

Reduce excess and unnecessary weight in your Armada. Even though your SUV is capable of hauling 97 cubic feet of cargo, don't drive around with it filled with items you don't need. For every 100 extra pounds you carry around in your Armada, fuel efficiency is reduced by one to two percent.

Step 5

Drive no faster than 65 mph on the interstate. Department of Energy statistics indicate that fuel efficiency is reduced by 7 percent for every 5 mph you drive in excess of 65 mph. When accelerating from a complete stop, do so slowly and evenly. Quick accelerations can cut your fuel economy by as much as 20 percent.
