Fuel Consumption

Just for kicks and giggles this morning I was attempting to calculate the fuel consumption of the 3vze in gallons per hour. I may be a little off here but I figure someone can look over the math.

I used 60 miles per hour just to make things simple.

60 Mi/Hr X 1 gal/17 miles (mpg reciprocal)= 3.53 gal/hr

1 hr/3.53 gal X 17.5 gal (approx tank size)=4.96

Note the following:
1. For mpg I used 17, since this is freeway speed assuming flat, no wind, sea level or close.


2. Miles per tank:

4.96 hrs X 3.53 gal/hr X 17 mi/gal = 297 miles / tank (seems a little high, but close)

I understand the fuel consumption will change throughout the rpm range and will also vary with load and all sorts of other stuff 4wd etc.

I was really curious how long the truck would sit at idle before exhausting the tank.

I was also wondering what kind of milage people were getting in 4wd, slow trail type stuff under 20 mi/hr

I've gotten as low as 11mpg on a trail run. That same event I averaged better than 23mpg on the highway on the way home.
