12.9 Average MPG on 05 TB LT. Help!!!

12.9 Average MPG on 05 TB LT. Help!!!
So I recently purchased an 05 Trailblazer LT with about 60K miles as a 2nd vehicle to have more room for our newborn. I bought the car from my brother, who took good care of it. I knew I wouldn't get great gas mileage, especially being used to my other car, but this thing seems to be eating gas like crazy!
The vehicle's meter is telling me I'm getting an average of 12.9. Is this normal???
I have a partially bent exhaust pipe leading into the resonator, which I'm assuming could be contributing to the problem, and possibly a small exhaust leak and I plan on getting that fixed this weekend. But could that alone really be the cause of getting such horrible mpg's?
Overall, the truck performs fine. No issues. Is there something I should have checked? Are there any aftermarket mods that can be done to get better mpg's? Does itsound like I have a deeper problem contributing to it?
Thanks.

The average fuel economy is:
2005 Chevrolet Trailblazer Ext 4WD
5.3L, 8 cylinder, Automatic 4-speed, Regular Gasoline
13mpg city / 18mpg highway / 15mpg combined
2005 Chevrolet Trailblazer Ext 4WD
4.2L, 6 cylinder, Automatic 4-speed, Regular Gasoline
12mpg city / 17mpg highway / 14mpg combined
To help improve fuel efficiency, consider the following:
Observe the Speed Limit
While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 60 mph.
You can assume that each 5 mph you drive over 60 mph is like paying an additional $0.30 per gallon for gas.
Observing the speed limit is also safer.
Remove Excess Weight
Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your MPG by up to 2 percent. The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones.
Avoid Excessive Idling
Idling can use a quarter to a half gallon of fuel per hour, depending on engine size and air conditioner (AC) use. Turn off your engine when your vehicle is parked. It only takes a few seconds worth of fuel to restart your vehicle. Turning your engine on and off excessively, however, may increase starter wear.
Use Cruise Control
Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.
Use Overdrive Gears
When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear.
Keep Your Engine Properly Tuned
Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent, though results vary based on the kind of repair and how well it is done.
Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.
Keep Tires Properly Inflated
You can improve your gas mileage by up to 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.3 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.
The proper tire pressure for your vehicle is usually found on a sticker in the driver's side door jamb or the glove box and in your owner's manual. Do not use the maximum pressure printed on the tire's sidewall.
Use the Recommended Grade of Motor Oil
You can improve your gas mileage by 1–2 percent by using the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1–2 percent. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1–1.5 percent. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives.
I hope this information is helpful. If you have any additional questions, please feel free to contact me.

Wow! So I'm actually getting .9 better than rated in the city huh? I had no idea the mpg's on this model was so bad. I guess it beats a car note! lol. Other than good driving habits outlined above, are there any tried and tested aftermarket add-ons that work to help acheive better mpg's on these models?

I'm sorry, but I cannot offer advice on aftermarket parts. I'm sure others from the community will offer some suggestions.
