ok not exactly 4000 miles but DANG close... 3982 miles this past week when the wife and I went to florida for vacation. i was pleasantly suprised at how well my 02 Dually did with fuel.
Odo start - 189945
Odo end - 193927
Gallons used - 207.3
On the way down from Michigan we cruised at about 2-3 MPH over the speedlimits. once down there just cruised around... only getting on it when needed, most of the time the truck was on cruise. on the way home from Auburndale to Atlanta was stop and go traffic. From Atlanta to home we cruised 80-85 MPH with some bursts faster to pass (time to get home). We stayed in Auburndale, visited Tampa, Paradise Island, Orlando, Miami, Key West, and other areas i forget. Probably could have gotten over 20 MPG
if my fuel bowl didnt start to leak halfway thru the trip, it would leak about a quart an hour at idle, no idea what it was doing going down the road...
For mods on the truck they are as follows.... Stage 2 Injectors, 38R, exhaust, DIY
intake, built trans, PHP chip (this trip was ran in the ECONO setting the entire time). for gears i got 3.73s and running cooper discoverer A/Ts @ 80 PSI
lets just say im alot happier i took my 9000 LB
truck rather than the 02 explorer as it only gets about 15 MPG
on a good day...
