Question: Drop in MPG

I was consistantly getting mpgs of 16/city 19/ hw for the past 1 1/2 years on this SUV now I am getting 14 mpg in town and on and on the high way. I keep up on all the oil changes and just changed the air filter and nothing still 14 mpg

If you are getting close to 100k, then you are due for some maintenance (see 'your service schedule' link on this site) which could make a difference. Otherwise, here is some fuel mileage info:

I already did all the suggested maintainence that is suggested and I have already read the link you attached before. When I purchased this suv I had read up on all the fuel economy info and I realize I was getting better than what it was rated for how ever I do not excellerate fast and drive keeping the rpm under 2000, I even calculate my mpg at each fill up and consistantly had gotten 16 to 17 on the same route I take to work every day and same ruitiens on the weekends. I have put full synthetic oil every oil change ever since i have owned my Armada. Do you have any other suggestions?

Depending on where you live, the local gas stations could have recently switched to a different gas/ethanol blend (you can ask the manager or call the company), which would affect your mileage. Beyond that, there are many item on the vehicle that could affect the mileage, like tire pressure, brakes grabbing, partially blocked exhaust, etc. You can try getting it scanned for codes and have the charging system output and the emissions tested, but at this time, it's kind of like a treasure hunt because the scope is so broad. You may want to try posting on the owner forums, to see if anyone else is experiencing something similar. If you google '05 armada forum' you will get a list of links.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
