Ted, that nothing to complain about, that is for sure! Thats great for a 5.3L V8!

 

I've had my 2001 Monte carlo LS since the end of January 2009 and I have never had lower than 23-24 mpg in city driving. My trips are usually shorter than 15 miles each way and I have gone as much as 350 to 375 miles on a tank of gas of city driving and that is with 160,000 miles on it.

 

I recently made a road trip up to Duluth, MN. I got 33.75 on the way up, 30.8 on the way back (fighting the wind). Both trips were with the cruise control set at 70 MPH.

 

2001 Monte Carlo SS 3.8L V6, Stock (Just bought it)

I average about 30-32 miles per gallon. My commute and driving is about 10% city driving and 90% highway. It's awesome to have something with power and gas mileage. My sister's saturn sl1 gets around 3MPG better on the highway, which is really saying something because it has a 4cyl and doesn't feel nearly as solid, not even going to mention the take off.

 

I see fairly consistant mpg with the montes..... right now my avg. is 24 city drags it down some due to the fact i have somewhat of a lead foot..usually on the highway where i spend most of my time i usually get around 28-30..I dont think thats too bad for a 5.3L

 

thats awesome for the ls4 i average around 16-17 mostly city.
