Post subject:  Over dive in the springs?

Since I live in the more hilly part of the springs, i ws wondering how people are using their overdrive switch. Do you drive without overdive in the city? Do you turn if off and on depending on the nature of the road. Do you even turn it off?

I tried to do some test, turning it off for stop and go, hills, and turn it on just for curusing, even if it is 45 on the flat side of academy or 50 (yeah right 50) on the flat side of powers. But since both me and my wife drives it, some times we both forget and so don't know for sure if there are any real benifits.

At one point in time, I was driving all the time and it seemed that i got better gas milage (two or four miles or so) changing it for the type of road and traffic. but now, I don't see that any more. I have done the following changes;

Using mobil 1 every 3-4k and oil filter of course. I use the Mobil 1 that is stated for SUV and trucks. I have the bosh platinum+2 (change the old ones at 26k and I am at 28k now). Rotate tires, Changed the xfr case and diff fluids at 26k as well.

Going to get the trans fluid changed at 30k. Might even have the radiator power flused as well. I got it used, and it was a rent a car for 15k of its life. so, I figured I change everything just to be at a base line for my self. but it is just taking time as I had to learn all this stuff as what to do for a 4x4.

It really should not matter unless you are towing a heavy load or have theKJ loaded down inside.Keeping the OD on empty in hilly terrain will not hurt anything,then again locking out OD will not hurt anything ether unless you are doing 50 mph or faster then your mileage will suffer.I don't lock out my OD unless I'm towing my trailer.

The only time I ever turn off my OD is when I'm up in the mountains or when I'm towing. On a couple of occassions I also turned it off when I was doing about 45mph and the trans either wanted to be in OD or 2nd.

I have been driving with mine off around town. With 32" tires, I get a lot less gear shifting. Even some of the smaller inclines would cause it to downshift. It seems to help with mileage, but I may just be kidding myself. I do think it is easier on the tranny though.

that is what I have been noticing, it always changeing gears on hills, it down shifts a bit to early i think. If I had a 5 speed stick, i would not go to fifth for a hill. or I would shift at later times, so I have an auto and it is 4 speed.

My overdrive stays on 100% of the time regardless if I'm towing, mountain driving etc... than again, I have a CRD and gobs of torque,

Later
