Your gas mileage sucks!

I just checked mine again today and fully loaded for camping running 50
miles in 3rd gear 4x4 low and the rest on rural roads (top speed 50 mph)
through towns with stop and go at lights and I just did 260 miles from
the last fill up and put in 60 liters.

Conversions are a pain, but I believe that works out to about 17 mpg. I
guess it would be city/off road more or less.

Just running on the highway, I normally get 21-23 mpg or so.

I have the 258 with the BBD and no computer turning 3.31 gears with 33"
tires on a 3" lift. I kinda like that damned BBD, it performs for me
and I don't mind doing a tune up every couple years....

Hi,

If you were driving a lot on pavement in 4H, you *may* have stretched
chain in the t-case. If the chain stretches enough, you can wear a hole
in the t-case.

The graphic on the shift lever is kinda misleading, if you don't know
that the line is the shift pattern...

Your t-case shift movements should be:

2H 2wd high range
| shift down to
4H 4wd high range
---- shift to the right then down slightly to
N Neuteral for towing (leave transmission in 1st gear when towing)
| shift down to
4L 4wd low range


You will know when you are in N because you don't go in any gear. You
know you are in 4L, because you can start the car in 5th gear and not
clutch the engine.
