O/D use?

I read something here once, but can't find it, now. I have a '99 WJ with the 4.7 V-8. I'm not sure when to use the O/D. I don't tow anything ( I may someday, just don't now), and most driving is only a few miles back/forth to work but it does include highway time. Is it preferable to use the O/D on a regular basis, or only when towing loads? I know nothing about what it's function is other than when I turn it on, my rpms go up. Does it effect the already crazy-bad gas mileage (12-16 highway, 10-12 city)?

All overdrive is in another gear. When you push the button to turn it off you're just keeping the transmission from shifting into the highest gear.

Od is always on. Leave it on, unless you're towing.

Typing on phones sucks.

Ahhh, I was confusing "off" with "on". D'OH!
