Drove from Houston to Baton Rouge and back yesterday. 3 people in the car. Some luggage, not too much.

Gas mileage:
Houston to Baton Rouge (Gas: Shell 89) - Average speeds 85-90 mph, no cruise control - 19.11 mpg
Baton Rouge to Houston (Gas: Shell 89) - Average speeds 70-75 mph, 50% cruise control - 27.5 mpg

It was hard to believethe numbers atfirst, but just a 10-15 mph reduction in speed,in addition to smoother acceleration and driving,increased my gas mileage by 8 mpg which is a lot!It surpised me. But driving at 70 mph with the cruise control on is really boring though.

Thought I would share, especially with gas prices being such a soresubject with everyone.

 

Good numbers! The max I've gotten with mine is 23 but I havn't taken any long trips yet. Good to know with the correct speed to drive at.

 

Right now my 2.7t is getting 18.6 with everyday driving.

 

I wish my everyday driving involves more highway, I'm only getting 17.4 mpg, everytime I come out from a red light it's alway 6.X to 5.X, and it hurts to see those figures..

 

haha, my 2.7t was getting 14.7, but after an oil change and your average 4,000 mile work its about 17! before I chipped it was 19.5!! I drove like an old woman though

 

I get 19 in city...thinking its low for the model and engine but maybe not.

 

Around 14 in town and 25 on the highway in my 05 4.2.

 

I usuallu get 17-19 in everuday driving which involves traffic in town driving mostly and short distances. Going to the beach thru mostrly back roads and some 4 lanes, I got high 23's. HWY probably 24's

 

Well my 01' 2.7t got to 15.5 and now down to 15.3 and isnt moving for sh*t.

 

Cruise control at reasonable speed makes a big difference in mpg - but it is boring. If I cruise to Detroit at 70-72 I get about 23-25 mpg; when I drive at a fun speed like 75-85 it drops to 21-22. I've never had the patience to drive at 55-60 but the computer shows 27-29 mpg at that speed for short distances.
