I guess that this is something that everyone should know so, shame on me that I have never learnt that.

Could someone please explain in very simple steps how one could measure the fuel consulption of a car without the use of any tools?

 

You fill up your gas tank
you set your trip odometer to zero
you drive around for a few days
you fill up your tank again
you divide the miles on the trip odometer by the gallons you put in.

 

I tried this method and kept getting 9.733

Does that sound right???

 

Depends on how you are driving.

I can get 24 MPG cruising in 6th on the HWY
I can also get 6 MPG doing 4 / 25 minute runs on Pocono Raceway.

 

Just got my new 2007 black M/T GT.. Only had 3 fillups so far but the mileage per tank is as follows :

1st tank 17.0 mpg
2nd tank 15.9 mpg
3rd tank 15.65 mpg

The more I break it in, the more I raise the rpm's. Hope the mileage doesn't dip below 15.0mpg combined street and highway. Can't wait to hit 9000 rpm's when I reach 1000 miles. Only 250 more miles to go.
