Hello!

i have a 2005 ZX3 se.

I have:

Changed the Spark Plugs

No Air Filter..it has the box thing...

Cleaned the MAF Sensor

I have proper tire pressure.

SO...what else can I do to get more MPG's per gal. of gas????

First off, how are you measuring your MPG? Are you taking the amount of miles you drive and dividing it by the amount of gas you used?

A lot of other factors will affect your mileage:

- running the car's a/c compressor or windshield defroster/defogger
- extensive stop-and-go driving
- automatic versus manuall transmission (you didn't post what tranny you have)
- do you drive "like a granny" or do you tend to boot the car and take corners hard?
- gas formulation being used at the gas station(s) you're filling up at (especially if you're in a colder climate, the recipe used by gas companies might be different, and you'll end up using more gas)

Sorry!...

Its an Auto...

Using Chevron 87 Octane.

on an average tank I let it go no lower than the 3 quarter mark....So I usually get bout 145miles doing suburbia driving...stop & go...etc..

Now driving on the freeway...going like 75MPH...I can get 189miles on a tank.

That just seems VERY low for a 4-Banger.

My other car is a Scion tC w/ a 2.4 Liter DOHC engine that get Twice the MPG's as the Focus...

Should the Focus be getting better MPG's?....since its Smaller & Lighter?

Stop being lazy and shift your own gears The autos on these cars do kill the mileage. That being said, your mileage does seem low. I average 32-34 w/ my mostly highway commute. I've gotten as high as 39. In town, I figure I get somewhere in the mid 20's.
