Jeep Liberty Diesel Oil Questions



  • I just bought a 2005 Liberty and plan on using B99 Biodiesel in South Florida.
    I have had great success with my 2001 Freightliner FL70 3126 Cat.

    The secret to success with Biodiesel is slow intergration and filter changing.
    5%, 10%, 20%, 99%
    This process took me 3 months to do.

    Is there anything I should know with the Jeeps operation on B99?
  • George,

    Can I get the name of the dealership and service manager you brought it to.
    I want to know what went wrong and why.
    I'm going to run B99 and want to know if I can override these problems.

  • Dear Gang,

    Let me tell you what happened with the BioDiesel in my 2005 Liberty.
    I went to the store and out of the blue lost 90% of the engines power.
    However, when I put it in neutral I got 3-4000 rpm.

    This is a sign that the BioDiesel is cleaning out the system.
    At this point my buddy who has been a diesel mechanic for 30 years said to shut it down before the glow plugs melt.

    I changed the filter. It ran fine again.
    Remember....carry an extra filter and one pint of BioDiesel (in a non-plastic container) in the Jeep.

    If anyone has questions, please feel free to contact me.

    After a Cat3126 in my FL70 and the Jeep CRD I think I get it by now.
  • Hi! I was wondering if you have figured out the problem? We have recently bought a 2005 Jeep CRD and are having this issue. Please let me know. Thanks!!!

    Hi slowzuki2003,
    Some oil additives seem to migrate through the hose material. There is nothing to worry about besides getting your hands dirty.

    I have a 2005 Jeep liberty diesel and it is burning oil. At idle I get a large amount of smoke from the exhaust This is engine oil smoke and not diesel smoke. I have replaced the Pressure relief valve that is connected to the intake (preturbo) and that did not remedy the oil smoke from the exhaust. My concern is: could it be the turbo seals or is it more likely to be piston ring failure? I have no power loss and it seems to be running fine but the other cars at the stoplight get smoked out when I'm waiting for the light to change. It is really embarrassing to be driving such a nice vehicle and to have it smoke like the engine is going to blow up. Please help!!!!!!!

    I have this same problem and I replaced the pressure relief valve and clean all of my intake hoses. My problem is that my jeep smoke at idle at stoplights and stopsigns. I am wondering if anyone has had this problem as well and if I should be concerned about turbo shaft seals or if it's a more pronounced problem like piston ring failure.

    My comments are directed at those who complain about the poor quality of the Jeep.

    Let us face it, the issue is not so much the engine as in the care or lack there of, not following the reasonable guidelines set out by Chrysler, the use of inappropriate lubricants, and on some occasions poor dealer/service quality.

    Let us face it, America is really not ready for good quality European diesels. Americans are not willing to invest the few extra minutes it takes to keep these engines running properly. Let us also consider that most American diesel fuel is swill and it is a wonder that these engines run as well as they do. I add goodly amounts of cetane improver and other additives to each tank of fuel resulting in less smoke, easier starting and better overall performance.

    I have spoken to several MB diesel mechanics who have told me that when the MB diesels arrive from Europe they run beautifully but after a few tankfuls of American diesel, they do not run as well. Whatever component failure they do see, especially turbos is usually a result of poor care by the owner. That makes me wonder. At my dealer, the tech is really very good. They have several other customers with CRDs who do not care for them as they should be cared. I have, with the dealer having asked me to do so, spoken with at least one of these people in an effort to help them. I have pointed people to this and other forums and had them look especially at the advice given by Caribou1.

    I know we are all busy, but investing a little time into caring for this very good engine has big dividends.
