Contrary to others I will stay with Mobile 1 0-40. However. No matter what brand of oil you think is best, I would stick with synthetic oil 0-40. The 0 is where you get the better starts and even fuel mileage. If you think fuel additives help then use them. I personally have found no benefit from these additives, perhaps with only 10,500 miles I dont need them or not able to notice their effect. I differ with some that say to change the oil often. I change my oil every 9,000 miles, until I see the need to change it more often.
I have noticed that there are those who give their CRD
a lot of attention, more than their wife, perhaps. I do not get to deduct or claim this CRD as a dependant at tax time so I will give it only the attention called for in the owners manual. Good Jeeping.

I have noticed a difference in mileage and performance with changing the differential fluids to synthetic as well.
I had gained about a 1 mpg better on average,so I believe every little bit counts.
This was a nice suprise ,since I was getting it done for the warranty service interval.
But also for peace of mind since I do tow periodically.
The 245's you speak of, will fit,but you'll have to grind off the plastic ,and metal ferrings,for the mud flap mounts to get them on.
In my opinion unless your adament about an extra inch of ground clearance,there isn't much difference between 235's and 245's.It just alot less trouble.
If that is the case just get a lift kit,then they'll fit easy.

About changing your oil..
You might also want to get a passifier for leverage.
for the wrench.She'll be a little tight at first.
Be careful when taking off the plug ,there is a retainer washer underneath.Treat this like gold as it will help keep the seal from leaks.
And no...you don't have to get a new one every oil change.
I would inspect it to make sure there isn't any gouges in it.If so then change it. It seats against a flat surface so I doubt it'll have to be changed.
Good luck ..

To answer your questions.
1. The boost solenoid filter has been mis-labeled. It is actually the vacuum solenoid filter. Look behind the air cleaner air box. You will see a small plastic filter with pleated paper hanging down. That is the filter in question.
2. There is no break-in oil per se. It is the Mobil 1 0W-40 oil. I would watch the level closely for the first five to seven hundred miles. Some people, including myself, experienced some consumption (up to a quart) during this period. I got rid of my initial factory fill at about 1.5K miles. It felt gritty in my fingers. Changed it again at 4.5K miles but to Amsoil 5W-40. I will be changing it again in late April or early May but will go to Amsoil 15W-40 until the November. By then, ULSD will be entrenched and I will go back to the 5W-40 once again. Be sure you change the oil plug gasket with each oil change.
15w40 does flow at -51F. With your experience with amsoil, should we really be woried about winter time. It's the warranty that bothers me not winter temps. Do you use amsoil oil filters and are they donaldson's. I saw the donaldson amsoil air filters. Only the one for cummins has an extra foam "prefilter?" The filter is not washed like aem nano fibers but is wiped or vacuumed. How does one get the grimy mess off them. Are you using amsoil air filters?
As far as the oil filter I went with the Fram Tough Guard. Has a 99% micron efficiency vs. 96% for some of the leading competitors including the plain orange version that they sell. Tough Guard at Wall Mart only an extra $1.25, again, cheap insurance and piece of mind.. what's left of it anyway. :sick:
At one time did use their foam air filters. I stopped using them because they were a pain the butt to clean and oil. I use K&N air in my wife's Chrysler but use Amsoil oil filters on both. Never had trouble/issues with them in the many years I used them. Unfortunately, Donaldson does not make filters for our CRD. They make filters for the big stuff like Mack, Kenworth, Peterbilt, etc. Amsoil does have a "nanofiber" oil filter that will fit the CRD and I intend to use one when I change oil in April. For now, I am going to stick with the stock paper air filter until I see something specifically designed for the CRD.
I have considered a K&N in the CRD but there have been enough postings that have stated that there is a decrease in fuel economy when using them. I have read this in articles about VW TDI and MB turbo diesels as well as in this forum.
Thanks again.
One of the things I have learned is that I can alter my cool time somewhat depending on the type of driving I do. If I have been on the highway and then get into stop and go driving once I am off of the highway, I take into consideration the amount of time I sit at a light(s) and shorten the cool down time by half or more. The other thing I will do is unload the Jeep after shopping while the engine/turbo is cooling down.
Surely, you mean haul!

The VW Toureg is out of my price range and an Excursion is too massive for my better half to navigate. I've never been that big diesel fan until I heard about bio-diesel and WVO. Now, I'm all about it. I just need something big enough for my family of 5 to travel 1,000 miles to grand ma's house for Christmas, and have enough room to carry most everything. I would love a Commander sized vehicle.
I'm not hugging any trees with bio-diesel, but I like the price of the homemade stuff and the fact I'm not sending money to the Middle East or Venezuela. By the way, those places don't like us, but we keep through money at them and they use it against us.
No more politics, but would love to hear some info if anyone has it.
Also, the Dodge Nitro (a bigger Liberty) will.
Jeeps upcoming 4 door Wrangler eventually will.
Time will tell for sure (and the EPA 2007 laws). :mad:
I've heard rumors about future diesels in Jeeps, Suburbans and other SUV's, but nothing has been confirmed. So, here's what we're considering for the interim:
1. A used diesel suburban. I've seen a handful of 98-99 models that are reasonably priced and appear to be in reasonable shape.
2. A Duramax based Chevy conversion van....kind of expensive, but it may be worth it given the limited choices out there.
Hope this helps.

The topic of cavitation is increasing my concern for yearly monitoring/maintaining the condition cooling system along with identifying an SCA to include when doing a cooling system flush and fill.
I have a model 2003 and it must have been a prototype series for yours. In fact I haven't found any sensor besides my turbo pressure sensor on the intake manifold.
On yours the emissions controller seems to use an atmospheric pressure gauge before the filter + flowmeter + turbo pressure gauge combined with the egr air control flap and egr position feedback. Mine is a chopper compared to yours
Winter2 and I have been avoiding the provent issue. One suggestion mentioned a long time ago was to make the factory stock ccv hose go uphill (to let oil drain back) before going down to the turbo. I believe winter2 is looking at 15w40 to keep the oil in the motor.
Our "pilot" vacuum if disconnected will through a cel.
Thanks for the resistor padding value-I probably won't try it-computer programming. Is your exhaust the same inner diameter from the exhaust manifold back? That is an easy big improvement in highway kpl's and performance.
retmil46 at lost talked about the freightliner ceo telling them the 2007 emission vehicles are better performers than ours because no emissions activity was performed by engine manufacturers thinking that the friendly business party in power would make the current emissions go away. Maybe we should just hang in and buy a new diesel from whomever we like very soon.
We bought a 7yr/100,000 mile extended warranty. Maybe we will give it to the next owner.

I can't believe it!! The check engine light has not come on for almost 2000 miles!! The redesigned EGR and EGR Air Flow Control Valve seem to be working well (Yahoo!!)
Seems to be a lot going on here in the two weeks I was on vacation, but not a lot on the EGR problem. Maybe those issues are finally being resolved. This CRD Liberty is really a great little car! Now if only that check engine light would never,ever come on again...!
Just about ready for the second oil change and I will be staying with the Mobil-1 SUV 5W40. Anyone got suggestions as to what the best brand of oil filter might be??? I am leaning towards a Purolator but am curious as to any input you might have. Thanks.
As to the Amsoil 15W-40, again, it specs out so closely to Mobil's 0W-40 and 5W-40 oils, I see no harm in using it. Plus, Amsoil's base stock comes from plants in this hemisphere and not from the middle east.
The other day my wife and I did a test drive of a VW Jetta TDI and I loved it. :shades:
