Jeep Liberty Forum : “How many miles will I be able to put on my jeep liberty”

if you have the in line 6 cylender,expect,350.000 or better.

The 3.7L V-6 in the Jeep Liberty (4.0L Inline six was never available in the Liberty line-up) is an excellent engine which has been in use since at least 2003 across the Jeep/Dodge/Chrysler lines.  Expect excellent longevity.  You will want to make sure you keep up with your oil changes as early 3.7s had some engine sludging issues which have mostly been corrected with the newer engines.

If you want long life with little maintenance, go for the CRD (Diesel) model.  MUCH LESS MAINTENANCE and better long life.
