Is it auto or manual? And it could possible be the way he drives, if not hes over due for a tune-up.

I had a bad fuel problem, was losing some low end HP, so I took mine in for some suggestions. Turns out I had a bad torque converter, after it was replaced with some ancillary work I'm back up to getting around 18-19 in all city driving, highway is at 23-24. The two months before I had the work done I was down to 14mpg in the city. 
Also, the guy mentioned that over the last 6 weeks he's had about 80% of the people that come in tell him they've lost fuel mileage. He said he'd put money on the fact that we're getting more watered down gas these days....and on another note Exxon reported last Friday that they're earnings were higher for any other 3 month period in company history, which also translated into the highest 3 month earning period for any company in the world, ever!!

have to ask him about that. Did yours slip ? Pretty sure he said it was an automatic.

No, mine didn't slip at all, I thought I had a fuel pump problem as I had heard that was reported with 2001's, but my pressure, etc. was fine. The only thing I noticed was the engine bogging down on somewhat-quick stops, the RPM's would drop to 400-500 before the engine would rev to kick it back up to idle. Does his do this at all??

Or maybe he didn't do his math right?

Look, I'm special, dammit
First, I would suggest a good basic tune up.
Fuel Filter, Plugs, air cleaner and see what you come up with.
The plugs could be gapped wrong causing some problems.

About the watered gas,i wouldnt be surprised. I just changed my fuel filter and on the in line from the pump to the filter it came out orangeish red, but that couldve been cuz of katrina, im not sure but yea, i emptied the tank filled it, and then put in 2 bottiles of Iso-Heet water remover and gas antifreeze, 
. Cars running a lot better than before,(also used Redline fuel system cleaner) That water remover stuff is only 1.28 a bottle minus my %20 
but yea its worth the money to make sure theres no water in the fuel. I dont understand how you guys get such low mileage I get 21-23 city 30-32 highway.
