My 06 is a FWD model and has always averaged about 10 L/100 (23.5 mpg)
Stay light on the pedals, keep it tuned there should not be any tricks or modifications needed.
Only time I see milage really suffer is in winter, often trips are too short for the engine to warm properly. :frozen:

Haha yeah stay light on the petal. My college is about 35min away and it's a 40mph zone with lots of lights. Usually when I speed up I never go over 2500rpm, sometimes I don't even hit that. And its not that there's traffic, theres really not much, just staying light on the pedal makes a big difference, When I first got the car it was averaging 18mpg never being reset back to 0.

2005 M Luxury (3.0 , 4WD) .. 11 years old and just shy of 86K Mi. ..

My Ultraguage claims I am getting 15.6 MPG on the highway (stays at 15.5 elsewhere). I am unsure how concerned I should be about that. The all knowing internet says I should be getting UP TO 16/21, but again, its 11 years old. I don't drive like a maniac so I guess 15.6 isn't too bad(?) :confused:

Recently just replaced my Ignition coils at 85.5k, not much of a change, also cleaned the Mass Air Flow..

So yeah, here's my contribution to this thread, in the Mariner Manor :yes:

Don't look at the gauge... calculate it yourself.

I reset my trip meter on every fill up and then do a rough calculation myself. On good trips I get 25 MPG (9.2L/100km), at 90 kph (55 MPH).

Even with Canoe on the roof and pulling my popup trailer I get about 19MPG (12l/100km), at 90 kph (55 MPH)

I also think that light acceleration and low speed are biggest savers.

The K&N is pretty much a waste if you're going for as much economy as possible. If you're driving for economy you should not be pressing the pedal enough for the factory filter and airbox to create any kind of noticeable restriction on economy. The only mod I did to mine was to remove the cold air snorkel and let the factory air box pull air directly from the engine bay. Helps a little bit in the winter.

Also, +1 on not trusting the dashboard fuel economy readout. Mine tends to read 2 MPG high.

Or you can use Fuelly to calculate your mileage.
