yeah, I used to those things (including the ill-advised drafting behind a semi) back when gas prices peaked back in 2008 - a new term was coined: "hyper-miling". i certainly drive less aggressive than I used to.So anyway if I want to get great gas mileage here's what I do:
I use my cruise control a lot.
I don't stomp on the gas pedal.
I make sure my tire pressure is correct even adding 1 psi more than required. It won't do any harm.
I try to coast before stopping at the red light.
I try not to brake too hard. Remember that the gas you used to accelerate that vehicle is energy wasted as heat when you brake (assuming that you are driving on level ground. Worse when you are driving up an incline, free if you are going down)
Driving style affects mpg a lot.
Cruise control probably works better in the older CVT or any of the manual trans Compasses, but its not worth a hoot with the 9 speed auto. Too much frequent downshifting on the highway when you encounter a hill, or a breeze, or bump into a fly with your windshield...jeepney_driver said:I use my cruise control a lot.

Very true but where you live has a lot of influence on how you must drive, many parts of the world have a slower pace of life than others. People who have to do a lot of 75 MPH freeway driving and merging on ramps don't have the luxury of putsing around to get better gas mileage.jeepney_driver said:Driving style affects mpg a lot.
works just fine, i use it every day. sure it will downshift at times, all trans willCruise control probably works better in the older CVT or any of the manual trans Compasses, but its not worth a hoot with the 9 speed auto.

I'd be willing to believe its a touch better in the Latitude and TH trims, since they have lower final drive gear ratios than the Limited trim, but either way its still going to downshift way more than a traditional 4 speed auto tied to a V6. There is simply not enough torque in the lower RPM range of the 2.4, combine that with really tall gearing in my Limited trim and piss-poor transmission programming and you get downshifts for every slight breeze and almost every hill.mdram4x4 said:works just fine, i use it every day. sure it will downshift at times, all trans will
A quick reminder. US MPG and UK MPG are different since US gallon and UK gallon are different. So the values are not directly comparable. So a MPG of 40 for UK is about 33 for US.UK 2.0lt 170bhp diesel 9 speed auto
On a run keeping below 70mph can average just about 51-53mpg
Mixture of town and motorway - typical commute to work 38-43mpg
Driving more around 80-100mph mid 30s mpg
Fastest I've had it 131mph on speedo which showed 126 on the u-connect GPS

You left out winter-blend gasoline as a reason for your fuel economy drop during the winter months....I know my fuel economy will drop because of the snow tires and of course lower temperatures as winter approaches.
The US Environmental Protection Agency (EPA) says conventional summer-blend gasoline contains 1.7 percent more energy than winter-blend gas, which is one reason why gas mileage is slightly better in the summer.
True.You left out winter-blend gasoline as a reason for your fuel economy drop during the winter months.
From What is the Difference between Summer- and Winter-Blend Gasoline?:
Air resistance also makes a big difference.True.
I still think the tires make a huge difference, too. I'm talking about a 10% decrease.
