I get about 320-330 city and over 400 hwy.

 

MPG update.

Getting 400-420 on a tank.

Not tooo bad ay?

 

i dun know, when I took my cats and mufflers off, my mpg increased

 

Yes then with the pulse and glide method you can get over 70 mpg.

(Research: Prius Pulse and Glide)

EDIT: On a serious note you could put on narrower tirers & wheels.

 

I think I had 470 one tank once. Must have had a tail wind, and was driving in a state where the maximum speed was 70. Navi showed 30mpg, but was actually closer to 28.

 

I think i saw improvement after switching to synthetic.

 

Things like the Tornado have no real evidence to support them working. There are government studies showing similar modifications don't work. If they DID work, wouldn't Infiniti, and everyone else, be dying to put them on as factory equipment to promote their improved MPG?

There are things you can do, as outlined on this board and elsewhere, to improve your MPG. First, if you want to check it accurately, or at least as best as you can, fill the tank at the same pump, so it has a chance of shutting off at the same amount of fullness, for several tanks and average the MPG that way. Judging by how far you get on a tank is pretty variable, unless you let the tank run dry, which obviously is not a good idea!

To improve your MPG, don't accelerate quickly (some chance in a G, huh!) or brake hard, don't drive too fast (wind resistance goes up by the square of your speed, I think), drive at a steady speed without constant accelerator adjustments, keep your tires inflated to the recommended pressure (sometimes a little higher, but never lower), don't carry extra weight in the car, keep the windows and sunroof closed, be sure the spark plugs are good and the car does not need a tune-up (both are less of a problem these days, don't let your car idle for long periods (don't let it "warming up" for more than 30 seconds usually, and don't sit in a parking lot with the engine running).

I'm sure others will have additional suggestions.

Enjoy your car!

 

wow

 

In general, I feel the same away about these miracle devices. Companies come under pressure to improve fleet mileage, and if there was a device that could do it, they would go with it.

In theory, if they worked, but the car had a lot less perceived power, they may not do it on a car like the G35. But they would do it on the Camry's of the world. Wouldn't a 40mpg Camry help? And be cheaper than a Hybrid?

 

after i got my crawford plenum my MPG went up about 1.5 with same driving style......

 

After a bunch of mods, my milage is now to 30 mp2g.

I.e. 30 miles per 2 gallon

 

you sedans suck!
i get 280mi if i'm lucky. half city/half highway

 

Go buy a prius if your worrying about gas..i dont think any of us here baught the G to help the enviroment be a better place.

I'm getting about 205-210 miles per half tank...

 

There is an episode of Top Gear where Jeremy Clarkson drives some insane distance in an Audi A8 diesel. Some of the tecniques he used were feathering the accelerator, no heater and no electrial gadgets.

I think a trip computer would also help. To bad the 2003-2006 did not come with one like on our 2004 Passat, which displayed mpg.
