What are your driving habits? All city? All highway? Mix?
Do you have the heat or a/c on frequently?
When was the last time that your car had a tune up?

It could be a number of things to as why your gas mileage is low. Give us a little bit more information and others might be able to chime in. Some factors of poor gas mileage are listed below.
-Driving habits
-City driving
-Air filters
-Spark plugs
-Bad fuel injectors

Its a mix of city and highway I somewhat get on it but Ive owned the tl premium a cl type s and a 03 tl type s all of which gave me anywhere from 290 to 325 on a full tank.. what do u guys get on avg?

19 inches wheel will explain why you got low mpg, in reality your speedo is off if you doing 75 mph it actually going almost 85. Your mileage is going up slower than usual also.

I agree that heavy wheels will absolutely lower mpg, but the 3G TL isn't really all that heavy for a sedan and especially compared to newer sedans with AWD systems. 3400-3550 is average I would say. Now the 4G TL pushing 4,000lbs + is heavy. For reference, my C6 Z06 vette weighed around 3100lbs, and that's a two seater with light weight materials (some carbon fiber panels, aluminum frame, magnesium engine cradle etc). So that kind of puts things in perspective that they really aren't as heavy as one would think...for a 5 seat sedan.

Another mpg thread, wonderful.
Air filters make zero difference in mpg, ....... Nevermind.

I think the biggest difference in MPG are driving habits. For 7 months I drove the car spiritedly and averaged 21-22mpg on my mostly highway commute (29 miles highway / 4 miles city). I decided to change my driving habits to see what type of MPG I could achieve at 100K, and instantly saw a 5mpg jump over 3 tank fulls (went from 22mpg-27mpg).

260 doesn't seem to be out of the norm to me...unfortunately I get about the same. The best I have managed to get on a trip in this car is 24mpg and that is right after changing the plugs. My v8 cars that I have had have done better. I had 2 Acura Legends in the past and was hoping for the same mileage(28-34mpg) but that hasn't been the case.

Weeeee....this topic hasn't been beat to death yet today.
Miles per tank is a mostly useless number. It does not provide any reference to how many gallons are used or left. In my '05, I usually get about 300-320 miles per tank while my wife gets closer to 350-380. Why? I call it empty when it is at about 1/8 tank while she drives it till range shows less than 20.
MPG threads are also useless unless you provide lots of details regarding car, driving style, driving patterns, tires, engine, transmission, etc. It has been covered hundreds of times already on here that low 20s is completely normal when driving in a mixed city/highway environment. The more aggressive you drive, the lower the MPG.
Tires can make a difference as well. I dropped 3-4mpg when I switched off of the EL42 to Pilot Sport A/S+. I got back some of that when I switched to MXM4.
My averages:
- Normal Commuting - 24-29
* 24 if I am driving, 29 if she is driving
* This is our normal poking around town for work or pleasure
* assume 10-30 miles at a time with about 60/40 highway/city
- Road Trips - 28-32
* under 70mph to keep it above 30mpg
* driving at a steady 60mph will usually shoot into mid-30s
* driving at a steady 70mph will usually be right at 30mpg

Mileage per tank means nothing to me. MPG does. My '04 manual TL hit a high of 33.94 on a trip in September '05 in the summer with the A/C running the entire way. That reading was on the first leg of the trip; a 270 leg.
My average around town ranges between 24 and 25 MPG. In town for me means in my general area plus a small city of about 25,000 people. With the tires I have been using for some years, my highway mileage at 75 to 78 MPH averages 29 MPG.

"Jackass" makes a lot of excellent points. Miles per tank is irrelevant to me unless I'm in a position to try to break my own record for longest distance on a single tank, but I haven't been in that position in almost six years now. Too many variables go into the equation. Aside from the issues others have noted, other factors that come into play for me include where I am and whether I know what gas stations will be available if I push on (or what those stations are, if I do know the area); another issue is whether I will want to stop again.
For example, my wife and I just returned from a two-week trip to Florida. Drove south, took Amtrak's Auto Train home. On the way south I stopped for gas somewhere south of Richburg, SC, along I-77 when the trip meter was reading around 430 miles. I thought about pushing further, but there just isn't a lot in that area and I didn't want to risk it. We subsequently stopped for the night in Macon and I filled up the tank there the following morning before getting back on the road. We'd only gone about 250 miles and so I could have gone a whole lot further on that tank of gas, but I just didn't want to have to make an unnecessary stop. Later in the trip we were in Fort Myers preparing to drive to the Miami area and I had enough gas to get partway there, but not enough for the whole drive. So I filled up in Fort Myers because I know there is only ONE gas station on the "Alligator Alley" portion of I-75 that crosses the Everglades, and that one station is run by an Indian tribe who charge excessive prices because anyone who stops there will be desperate.
So those are all practical reasons why, to me, "miles per tank" isn't an especially useful measurement. I prefer my average mpg. As others have noted, that's a figure that will vary immensely. "SouthernBoy" lives in Northern Virginia, like I do, but in an area further out from the Beltway. The traffic isn't quite as bad there and you don't spend as much time idling at red lights. I tend to get between 19 and 22 mpg in city driving, depending primarily on what sort of driving I do on a given tank (e.g., am I on the local highways more? Am I out in rush hour a lot?). In pure highway driving outside major cities I generally get around 30 mpg even at average speeds up to about 73 mph. The six-speed manual TL loves the highway when you can leave it in sixth gear with the cruise control on. (Speaking of which, using the cruise control can help a lot with fuel economy too.) On our recent trip to Florida I averaged 30 mpg on the all-highway segments heading south and in the high 20s mpg on the other tanks of mixed city/highway once we arrived (we visited relatives in several different locations and so most tanks involved city driving at our destinations and highway driving in between).
Really, the biggest killer is going to be sitting there idling in stopped traffic or at red lights, because then you're running your car but averaging 0 mpg.

I've found the single biggest factor by a mile is average mph as indicated by the MID. in the old thread where everyone posted their average mph and mpg, we were all very close together regardless of driving style and mods.
Mine right now is 15mph and 13mpg which is normal for that mph.

I get an average of about 32-35 on the highway. 20-24 on the city streets. I am about to do my 105k service so spark plugs and filters. Hoping to see more around 34-37 and 22-26.
Also add to that list the type of tires make a difference. While it might be around 2% of an adjustment per tank, it still helps every little bit.

That 33.94 MPG I reported was on a trip to South Carolina. There were three distinct average speeds due to speed limit changes on the roads on which I traveled. The first was 55 MPH and we were running around 62 MPH. The second was 65 MPH and we ran around 72 MPH. The third was 70 and we kept it at 76 MPH. We left at noon, the outside temperature was 86 degrees, and the car was packed for a week's trip. The A/C was running the entire time.
Being that the car was only 14 months old, it still had the original OEM tires which were Bridgestone EL42's as I recall. They were touring tires so MPG was an important factor in their design. The MPG reading was done the old fashioned way; manually. I even parked the car at the pump in such a manner to emulate how it was parked at the pump back home when I filled up. So the 33.94 figure is accurate.

260mi/17gallons= 15mpg, not really that bad for mostly city and heavy wheels, I think it's only rated at 18mpg city/26hwy with the auto, I get 15mpg cause I have a short commute and a heavy foot, if I reset it and go on the highway I get 25-27.

My TL has been Swiss watch accurate in the MPG .vs. MPH metric. I know that every time I enter my fuel data at fueleconomy.gov. That site has cookies that allow the site to remember my notes that include the 'MID mph=xx mpg=yy' data. The site is often dead on, but might have two cached entries for one MPH value at times. I have 8 years of data on that site so it's been amply back-tested to show when my MID reads 26 MPH I'm going to realize 19 MPG. If the MPH is lower, the MPG will be lower ALWAYS.
I have also found the MID calculated MPG to be dead on knowing that there is a +/- .5 MPG for roundoff error since the MID shows an integer instead of a decimal. Perhaps those people with MID accuracy issues have changed their wheel size or something that could affect the calculation?

I installed the RDX injectors and the computer looked at duty cycle to calculate mpg. Since the RDX injectors flow almost twice as much fuel as the stock injectors, they were working half as hard or running at half the duty cycle tricking the computer into thinking I'm using half the fuel. Mpg at that point was closer to 21 mpg or half the reading and running 8 psi of boost on my commute to work.

Closest I've come to a tank's capacity was when I borrowed my brother's 1974 Beetle and he said to fill it up as soon as possible. It has a 10-gallon tank and the pump shut off at 9.6 gallons!
