I know it'* always said you get the best gas mileage at 55 mph but I've pulled 29 mpg when I drove an average highway speed of 85 mph on part of a drive up from North Carolina

If you want fuel economy you can write home aboutm then get an econobox or a TDI or something.

Otherwise, drive slower and be content with the fact that you get better gas mileage out of a large-displacement V6 in a heavy 4 door car than most people do with engines and vehicles 2/3rds the Bonne'* size.

you might think about changing out the 02 sensor on that as well...your mileage seems a little low to me, but then again thats just me.

im happy that i NEVER get below 20mpg no matter how hard i beat on her...but then again its not a 3800 either...of course i have longer stretches of cruising to even out the spurts of insanity.

Basically, what everyone has already said, and I'd add: Regularly check and maintain your tire pressure at optimum level. That will also save you early wear and tear and replacement costs on your tires.

But other than that, a lot depends on the roads you drive. If your typical daily drive takes you through high-density driving with lots of stop lights, then your gas mileage is going to suffer -and there'* nothing you can do about it. Your best mileage will be on wide open highways, so if you're lucky, your typical daily drive is mostly highway.

My daily drive to and from work for the last eight years has been a short 12 mile hop on mostly freeways, and I average 20 to 22 mpg on nearly every tank.

But if you want significantly better mpg all the time, you should get a car that weighs less than 3500 pounds, and has an engine smaller than 3.8 liters.

Fuel...from the sound of your desired driving technique. You won't have good mpg. change the technique and you could see great results.

All things considered, our cars do very well for their size and comfort.

Yeah, I forgot to mention I average 20 MPG. That'* with promarily rush hour traffic, and a "wussy button" (aka Remote Starter) which guarantees 15 to 30 minutes of just idling a day during the winter.

I have never gotten above 22, but I have never done a long trip in my car. I ALWAYS get 18, and my O2 is brand new.
