4wd vs 2wd: gas milage?

I have a 2000 GC Laredo V6, Selec-Trac. What is the difference in gas mileage between 2WD and full time 4WD?

You have an I6 4.0L (Inline), not a V6.

The difference is negligable...

Travelled to my parents today and was in cruise at 58(ish) read out told me 30 which is 36 mpg for me ( UK gallon being different etc)

NOT that i ever expect to do that other than on a day with a W in it, with a pink moon, following a 50ton juggernautt and singing "We Will Rock You " in a chipmunk style. ....still i DID get that read out for over 10 minutes

(my normal everyday mpg is 18+20% btw on 99 wj 4.0)

That was a NP231 T-case. The WJ uses the NP242 which has a full time 4x4 option that doesn't lock the case, giving it a AWD style setting. It's fuel usage compared to the 2wd option, is almost identical.

Quit complaining, gas is set to go as low as 1.15 in the not so distant future.
