    I am a new member and looking to purchase a 2005 Wrangler after my beloved 1998 Cherokee was totaled. I am interested in feedback on the 2.5 engine vs the 4.0 regarding maintenance and longevity. I am pretty familiar with the power situation. Thanks

    Welcome! Both engines are tanks, and will require similar maintenance. Arguably, I would put longevity if the 4.0 higher than the 2.5.

    4.0 is a lot better than the 2.5 higher torque lets u pull more plus last a lot longer the the 4 cylinder

    5" lift, 4.11 gears, tru-trac limited-slips, winch, bumbers... you know the rest.
    So in 2005 the wranglers came with the 2.4 DOHC or the trusty 4.0. I've owned both and worked on both. The 2.4 is higher maintance and has a timing belt but gets about 22mpg on average and the 4.0 is bullet proof but gets 17mpg on average. I vote for the 4.0 it has good power, longevity and is very modable. I was getting 20mpg on average with my 06 wrangler 4.0 with the right mods.
