Model: 4Runner
Year: 2006
Engine/Size: 4.7L V8
Transmission: 5-speed auto
Mileage: 12,000
Tire Size: 255/85R16
Gearing: 3.73 (stock)
Weight (if known or approx): Bone Stock: 4,520 Current: 5,440
On highway MPG:
Original stock baseline, repeatable flat freeway test loop @2,433-miles: 55.8-miles, 65-MPH (66-indicated) 20.94 MPG. Computer/PCM display claimed 22.6-MPG.
Since all my modifications/weight I have yet to repeat the above test, but think it will be close to 17-18-MPG. Odometer error is known and factored in. A few recent, interesting mostly freeway/highway trips yielded the following:
Trip from Reno to Eugene OR, then over to the Oregon coast, and then back to Reno. Total miles 1,199-miles. Trip average MPG- 17.808. High was the first leg of the trip at 19.41, low was 16.99
Regional highway trip at 60-70 MPH (depending on speed limits), 109.7-miles 19.84-MPG.
Total Trip MPG for my 2007 ExPo Trophy trip, includes:
Towing Chaser and Gross Combined weight of 7,840, off-highway, and a high-speed return trip home (all in one day). Total Miles: 1,808-miles MPG-11.82
In-town & freeway/mixed miles MPG ranges between 12.5 - 15.5
Off highway MPG:
Just like city/in-town driving there are far too many variables to give good comparable numbers, and my car is too new for me to have a real feel for different types of off-highway MPG I may get. Having said that...
My first 4x4 trip pulling the Chaser, not far from home & only a 30-mile round trip, almost all crawling in low-range, the PCM indicated 4.0 MPG going up the mountain, and it rose to 5.9 when we drove down the other side and as our speed increased a bit. That was probably pretty close/accurate, but I didn't fill up until I had driven a couple hundred miles.
Currently, for trips towing the Chaser and general mixed on/off-highway travel I'm figuring total trip fuel cost using 10-MPG. I’m hoping that turns out to be a bit pessimistic.
