Comparison of 3.0, 4.4, 4.6is and 4.8is

[pepatrick]

The 4.6is is a 5 speed. The 6 speeds did not come out until 2004. Both the 4.4i and the 4.6is get about the same really poor mileage...

Another thing we all compared was gas mileage. While the 4.8is and 05 4.4i claim they get better mileage...they all get pretty close to the same. My MPG button was not reset when I picked it up...we all compared..and mine was at 15.7 mpg and theres were about 16.0 and 16.1 mpg. Not enough difference to sneeze at. I took a 100 mile cruize this afternoon to my office and back and in no traffic nailed whopping 21.6 mpg during the entire trip at about 70 mph...I didnt think that was too bad.
