Jeep Liberty Diesel

unclebubba

I actually knew about this one! My brother-in-law drivers fuel tanker in SOCAL (southern california), and he educated me about gas/diesel and a brand having little to do with where it comes from. One brand that has it's own loading dock (in SOCAL) is or was AMOCO. When delivering to AMOCO they had to load only from the AMOCO site, right next to the other brands loading site. That was then, have no idea what it is now.

We discussed power service and redline months ago and I also stated I wanted something with post combustion benefits. I was also worried about strong synthetic detergents because of possible seal damage if viton was used.

Redline's tech sheet for their gas additive which I have used, claims that their strong detergents survive the combustion process.

A quick scan of their diesel catalyst whitepaper tech info refers to "thermally-stable detergents". The tech sheet also discusses diesel fuel seal leakage and swelling. Seal leakage is not unheard of.

That is why I think the combination of the power service(ps) and redline might have saved my egr so far.

Here or at the other places, I believe I remember someone stated that their egr failed and they were always using the year round ps formula w/anti-gel. Someone with I believe 15k miles finally had their egr go.

I still have summer and all year ps and now mixing with CRC (which warns about oxidizers, viton, and f?????). I may switch back to all redline products. The last time I saw redline it was still 4.99 at auto-zone but 6.99 or 7.99 at pepboys. CRC at napa is priced like ps by the gallon.

I'm trying to save my egr with additives with post combustion benefits. It seems the egr is a pain for anyone to work on - problems/mistakes have happened when some of them were replaced.

I'm in the dfw area and just changed my oil for the third time at 12,500. From now on it's every 6,000 miles. I'm still using 0w40 mobil 1 but since 5w40 is an approved option, I may "may" switch to that next summer.

We had a ford that used 5w20 (class III hydrofractured oil?). Have you read the ford/honda people edmund's board over that issue years ago - pure anguish. I anguished but used it with no problems. I think the oils now leave a good film for lube for the close tolerances of modern engines and I think the thin oil is used as an additional coolant as well as provide for high pumpability.

I don't have a provent - we have an additional 7yr/100,000
dc warranty with first day rental. I will keep 225 75 16 bridgestone's unless we move up north or to the country.

Uncle Bubba -

Gasoline is a fungible commodity. The various companies' proprietary additive packages are normally added at the rack. (This is where Texaco becomes different from Conoco becomes different from Sunoco, etc.) It sounds as if the terminal from which your brother-in-law was hauling was large enough that they had pre-mixed the additives (before the product reached the rack), which would account for different racks for different brands. Make sense?

This was a great post:
Shell: 45
Mobil/Exxon: 41 - 43
Chevron/Texaco: 40 (48 in CA)
ARCO: ULSD in CA 54
AMOCO: 45

It also got me thinking. If you go to the CRD website and click on the "economical" tab it will ask you for your ZIP code. When you enter it, it will show you Jeep stations that sell desiel. However, it did not show me ALL the stations in town. Oddly enough, the sites it did find were those listed above with a cetane of 45 or higher (in my case Shell and Amoco). It did not the four others that sell diesel for cars (LPV's).

I wondered why they listed only these two stations but I never inquired. You have solved my mystery.

Thanks.

Boiler -

Interesting site, but don't put 100% faith in it. It showed 1 Marathon in Columbus which has never carried diesel and totally ignored a Shell, a Speedway and a Thornton's at Taylorsville, plus a Marathon at Edinburgh, all 4 of which do carry diesel.

I think their information might be as reliable as Purdue football. GO IRISH!

There are Conoco in my area, none of them have diesel that is any higher than 40-45 Cetane.

Actually, I don't know of diesel (other than biodiesel)in my area that have diesel that is any higher than 40-42 Cetane and only 3 or 4 stations in all of Chicago that are suspected of having premium cetane diesel.

My 2006 Liberty CRD starts to chug after accelerating to 50 miles per hour. This usually happens after it has been running for about 10 minutes and only lasts a couple seconds. The vehicle only has 1000 miles on it, so could this be just part of the breaking in process?

rudolf_1

EN 590 is the European specification for Diesel fuel. It defines the fuel lubricity, cetane limit, sulfer content, among others. If we could define a similar standard in the US it would be very beneficial for all of the diesel related fuel and air management systems.

paulc7

I have been working privately with a service manager of a Jeep dealership , & have brought forth the egr concerns . He says he has not had any vehicles in for such service. They only come in for oil changes ?? There seem to be so many posts with egr concerns . , perhaps a stronger voice from all of you owners is needed. I live in Canada, & have been driving diesel vehicles since 1977 , never any problems . HELP :confuse:

When your head gets snapped back into seat,thats when the turbo kicks in. Speaking about turbo's,you have to let the engine idle a little bit to prevent the bearings from COKING. It is'nt because you have a diesel,it's because you have a turbo.I strongly recommend if you have CRD to get a pyrometer gauge.(exhaust temp).By the way,my engine light came on at 1900 miles.I had a 1/4 tank of fuel left.I went to the gas station and filled er'up and the light went off.Go figure.You people that are having problems,I suggest you drive it like a jeep instead of driving it like a Mustang GT!(Look out GT owners when I get a power programmer installed)since they have the same torque ratings.

banshee1

What smell and what noise? Try owning a 7.3 power stroke.The smell? I put my nose up to exhaust pipe and was able to keep it their. Try doing that to a gas engine. I love my CRD and hope to have it for a long time right along with my King Ranch 6.0.

vtdog: I am right there with ya. This is my first Diesel ever, and I am 60 years young. One thing I do know is that if I do it the DC way they will foot the bill if a failure occures. I get an honest 21.6 to 22mpg which is some what of a downer as I exoected to get 24mpg, I now have 3,800 miles on the CRD. I have used the BP Amaco fuel from the same station every fill up.

There is one thing I agree with totally, the tires that came on it were flimsey and thin. I changed them at 500 miles for 8 ply and made a more stable, just as smooth a ride as the oe's.

Perhaps time and experience will help figuar this out a little more easier.
Farout

vtdog

Hang in their with the mpg farout. My mpg was about what you are getting until after about 6k miles. I have about 12 now and get 24 +/- half gallon now on average. If I just do hiway miles its up around 26. I use an occasional tank of b-20, but not very often as the only place i can find it is not near me. The b-20 does not seem to change mpg, but it does run "smoother".

I still have original lousy tires on. I'm waiting until just before snow to change out. I figure every mile on these pieces of junk is one less on new tires. The goodyear people should be arrested for impersonating tire engineers.
I'm thinking about getting BFG Long Trails which is what I had on my XTERRA which I traded for the CRD. They are certainly not the best tire, but the price is good, they run fine, and I got alot of miles on them on the XTERRA.

farout

vtdog: Well that's incouraging that mpg seems to improve. As for tires, I went with the Goodyear FORTERA 8 ply tire. They say if you are unhappy with the tire in the first 6,000 miles they will put on whatever tire you want in the same price range. I live on a steep rough gravel road which we get snow and ice in the winter. So far I am pleased. This is the first time I have ever bought a Goodyear tire. For the most part I always dump the oe tires when I get a new car or truck. Time will tell. I traded my 2005 Liberty Limited in on the Sport CRD. Even with all the goodies I gave up, the SprotCRD rides and handels so much better. As for acceleration the 3.7 was slightly quicker, but was not near as comfortable. I think the heated leather seats are quite firm and hard to sit in foe long periods of time.

I do not blame Goodyear for the cheap tires it;s what DC said what they wanted, and they got what they paid for. Thanks for the reply.

The transmission went out totally on my liberty with 17,000 miles. DC had to replace the entire transmission. Has anyone else had issues. It happened when I was traveling and 900 miles from home, dealer took 1 week to get a new transmission. DC would not cover rental car and hotel expenses. I am less than happy with DC or my Liberty.

I honestly don't understand why Certane level is not posted like Octane is on gasoline. I am brand new to this diesel stuff, so pardon my ignorance, but why is the certane not listed?

I am also confused about all the requirements that seem to be needed like additatives for anti-gel, rasing Certane levels, and lots of ideas on how and when to change the oil to water sepperator filter, and the need to let the trans warn up before moving. Is all this extra attention needed for what is suppose to be a real tough excellent engine? This all seems rather complex. Why not just follow the "B" schedule, is that not good?

So far with 3,800 miles I have used no oil, had three times the engine jerked for about 4 seconds while in OD. I had the dealer show me how to drain the water filter, and none was in there at 2,600 miles. I like the idea of a efficant 4 cyc. engine, and if I could fine any Bio diesel near me I would try it.

Anyone with suggestions I would appreciate. I enjoy this forum because there are some real experts that seem very experienced at this diesel stuff. Thanks!

By the way, it's spelled cetane. I only mention it in case anyone else does a search using the correct spelling so they will be more likley find your post.

Over 7K miles on our CRD now and I just have to comment again on how cool this engine vehicle combo is to drive. It just keeps pulling the hills at such low RPMs you'll be amazed to recall it is only a 4 cylinder engine. I find it actually fun to drive taunting it to down shift, but it keeps lugging right over the top with power to spare. Gone are the deisel "dog" days. Mileage is up now that the engine is broke in. These engines will be "the" swap in choice for rock crawlers and trail rigs. Watch it become the most exported stolen vehicle on the insurance institute's list(not cool). Use the engine block heater and enjoy instant heat this winter(cool or not cool).

bullhead

Your post made me recall our trip last summer pulling a mountain pass grade at 6% with four persons aboard and a 2,500# travel trailer in tow. The stock 2005 CRD is somehow programmed to lug awesomely at about 40 MPH (OD. locked out). Now that was about the coolest music you could want an engine to make!

That being said, the sustainabilty of the condition is still a question mark. The engine temperature rose above the 3/4 mark pretty quickly (but it was 90-95 degrees F and there was a slight tail wind, which explains some of it). Yet, still very impressive for a "do-it-all" auto. Obviously, fuel mileage is soooo... much better at 1900 rpm versus well over 3,000 for an equivalent gas-powered tractor (well, that's what it becomes!).

We're all still learning what this vehicle can do. Perhaps it can do certain things even better with some aftermarket goodies and tweaking of its on board program.

I am looking for assistance in installing a brake controller to my 2005 CRD. I can not seem to find a plug or blue wire for the controller.

I have the 7 pin connection with the tow package. I have found that in the 2003 3.7L with a trunk release that a blue wire exists behind a white plate. However, my 2005 CRD does not have a rear release. I have about 600 miles on my new CRD and absolutely love it. I am glad I read the manual, otherwise I would have never know about the turbo cool down.

trumpet_washer

Methinks thou protesteth not enough. Without being profane, state your concerns to both the dealer and DC, in writing, with exactly the remedy you desire. When dealing with DC, remember to state that you have given the dealer ample opportunity to satisfy your request. Somebody will cough up the bucks, probably the dealer under pressure from Jeep. Good will has a price for car makers. They will pay to avoid having you tell everyone you know that you weren't treated well.

trumpet_washer

Many of the early model problems were TCO by Jeep. All the TSB services will have have been performed on a vehicle you purchase. My Liberty was built in July and purchased in October. I am now past the mileage where many of the early problems were encountered. Buy one and enjoy it! I wish we had the variety of diesel vehicles available in Canada.

paulc7

trumpet_washer: thank you for your reply. I will be considering a demo model Limited version. The manager will try to get the vehicle for my use for a weekend, for a decent test drive.Thank you once again.

semo1

I wrote a detailed letter to DC stating the issues and asking for reimbursement. Their reply was a phone call from a customer service rep who stated that it was DC's final position not to cover any of the costs. The selling dealership did not even respond. The dealship that repaired the vehicle did so when he had the new transmission so I dont have issues with them. My next avenue is to go to court that is why I am looking for others who may have issues with the transmission in their liberties.

biodieselman

To FAROUT, I am curious where you heard that you can swap tires in the first 6,000 miles. My 2005 liberty has the Wrangler ST version. They have a much more open and aggressive tread pattern than the factory tires on my 2002. Those were horrible in the wet slushy snow. They wouldn't turn worth a hoot. These tires seem to be better but if you know about their handling in the snow please tell us more. The almanac is predicting a snowy winter!!!!

biodieselman

My 2005 with only 300 miles on it does the same thing. It happens because you are accelerating moderately (as you should for good fuel mileage). If you were stepping hard on the pedal (and wasting fuel) you probably wouldn't notice that.

45-50 is the point at which the transmission shifts to the highest gear and the torque convertor locks up to eliminate slippage in the transmission. That just means the engine is having to slow down and pull at a lower RPM. The electronic control system won't allow that to occur until the engine has warmed up sufficiently. As long as it doesn't lurch or jerk there should be no problem, but always feel free to contact your dealer with questions that is what they are there for. If you feel there is a problem, always save the paperwork so you have documentation to prove you had a problem investigated at an early point. I once got a problem on my Dodge Omni fixed 1,000 miles after warranty expired because I had complained about it twice while still under warranty.

unclebubba

Makes sense to me!

trumpet_washer

Sounds like you are covering all the bases. A letter from the Law Offices of Grabyer, Purse, and Scram wouldn't hurt. Have them ask DC to put in writing what the CSR told you. Did you get a file process number or complaint number from DC?

winter2

When your head gets snapped back into seat,thats when the turbo kicks in.

Only partially true. Turbos kick in whenever there is a demand for power whether it is a little or a lot. It is not an all or none deal.

unclebubba

Just wanted to give you and update. Of course nothing was found at the dealers, I could not duplicate the action. Decided to try a cetane booster. I started using Power Service: Diesel-Kleen + Cetane booster and the "hiccuping" or "stuttering" as I call it has all but disappeared! Use 16oz. per fill up to raise the cetane number 6 points.
It may be my imagination, but the engine seems to be quieter and run much much smoother than before.
One thing I can vouch for as certainty is this: I have experienced an increase of just over 5% in mpg! That is a definite.

I picked up my new Sport last Wednesday and had 150 mile drive down from Flagstaff, AZ to Phoenix. There is one relatively long steep grade to climb out of and I was impressed that the CRD never shifted out of OD but just purred up the hill. Ride comfort isn't quite as nice as I expected (after reading about the differences between older Liberty's and the new CRD) but wasn't bad either, stiff, like one should expect from a Jeep I guess. (first Jeep). Dead stop throttle response is as has been posted on this forum, slow, but once rolling is quick to resond. Not the vehicle to shoot the gap in (coming from a 454 Chevy!)
I now have close to 300 miles on the first full tank and still have over 1/2 tank showing on the guage I hope the guage isn't like my Chevy which dropped fast on the second half tank.
I'm also use to a huge dash board to load extraneous stuff onto, the Liberty doesn't have this nice feature.
The AC works great (being in Phoenix this is a must). Radio sounds better than all my other vehicles including the upgraded system in my wife's Subaru Outback, now I just need the XM modulator installed!
This Sport came with the Wrangler ST's which seem to be OK, especially for the dry conditions I experience most of the time here.
All in all, I'm happy with the vehicle performance. Time will tell if it stays like that.

Hey Bubba !,
Where did you pick up the cetane improver?

I am trying to find a place that carries it.
Also what brand would you suggest?.
I already use Kleen Flo ,but can't find the cetane improver..
Speak Soon.

Hey,

Just had to get a new EGR valve put in at 15K. What additives do you use, and how do you Blow out the EGR so I can keep the new one from toasting out? Any other problem areas with the Diesel Liberty that I should take preventative measures against?

Thanks

winter2

Additives I use
1. RedLine: Diesel Fuel Catalyst. I get this from my local PEP Boys.
2. Amsoil: Cetane Boost Additive. Get this from an Amsoil dealer. Will treat up to 200 gallons of fuel.

I do not use them together.

How to blow the EGR's "nose"

1. Make sure the engine is thoroughly warmed up.
2. Lock out O/D.
3. From a dead stop or near dead stop, mash the gas. Get to 60 mph and hold it there for about 10 - 15 seconds. I had to repeat this process a few times the first time I did it to make sure all of the junk was out, namely no smoke out of the exhaust.

unclebubba

I actually found it at Advance Auto Parts store. Should be able to pick it up pretty easily at larger parts stores. The brand I use is made by Power Services (?) the name of the product is Diesel Kleen + Cetane booster. Costs about $5.25 U. S. for a 32 oz. bottle. I use half a bottle when filling up almost empty, to get a six (6) point cetane increase.
So far it is proving to be worth the investment. Good luck!

ungn

with about 2000 miles on the OD, I'm up to 24 mpg on my daily commute. My 2.0 Neon gets 28-29 on the same commute but it can't tow 5000 lbs.

Found a trick to get it to unlock the Torque Converter and idle down at high speeds going down steep grades in OD (like it does in the other gears).

Hit the OD lockout button twice.

Power Service in the white bottle (Wal-Mart) or Stanadyne Performance Formula both contain cetane booster. They do other nice things for your fuel, as well. Some companies, like Lucas and Amsoil and Redline make products which are strictly cetane boosters. (They make other fuel treatments as well). More than 3/4 cup of Stanadyne or Power Service is enough to treat 30 gallons of fuel. When replacing the fuel filter on my VW, I used to fill the filter with Power Service Diesel Kleen before re-installing it. Cleans the injectors REAL good. Also runs smooth, but at $5.00/quart it's a little pricey to run al the time.

lightnin3

Thanks for the info Bubba !,
I'll have to call a few more parts stores here in Windsor,Canada.
Most haven't heard of cetane booster yet.I may have to visit Detroit to get what I want.
I have been getting the engine light and
" EGR buzzing " ,and have an app't with the dealer to get it fixed.But I am looking for ways to avoid this again,until we start getting ULS Fuel,I'll have to depend on the additives like you guys suggested.

Oh I found out a way to get more Mpg,by using the cruise control.
I first set up the overhead console to read the mileage,
set cruise at 60mph,
push reset on the overhead console ,this will start a more accurate reading of mileage,
Then lower my speed to 51mph slowly till my rpm's are at 1700 without losing the OD.I ended up with 30 mpg on the console,now how accurate is this thing?.

I found better mileage at lower cruise speeds,if it is practical.
I experimented and found this,
lowered my cruise speed to 41mph - 33mpg,
and the best so far was 35mph - 40mpg,which just hummed down the road.
I have a 30 mile trip each day in 2 lane highway,where the speed limit varies 35mph 1/3 -65 mph2/3 of my trip,so I am going try and see if this will give me the mileage it suggests.
I find it easy to go to work on midnights following big trucks who travel at 50mph.
Most drivers here are curtious,when passing.
Anyways thanks again guys ! .

Speak Soon ..

Your statements about RedLine and Amsoil are wrong. Redline Diesel Fuel Catalyst does contain cleaning additives as well as cetane improvers. Amsoil's Cetane improver does contain cleaning additives too. Read the label completely.

Before the hurricanes I bought B-100 for $2.65 a gallon. Today the price is $3.92.9 a gallon. This is the customer appreciation that is being shown by Taylorsville Shell which is located on the corner of rt. 26 and rt. 27 in Maryland. Another note is that their dino fuel is NOT shell.

trumpet_washer

I have read them, and they do contain the stuff you mentioned. Diesel folk commonly refer to them more as cetane boosters than as fuel conditioners. Probably because until last year, Power Service didn't contain cetane booster.

I have a 2005 Liberty crd purchased in june, march manufacture date. The trans module went bad, dealer replaced and said they had to re flash the computer. After the re flash my OD locks up at 63 now. It use to lock up at 58mph and as a result my fuel economy has dropped because in 55mph traffic its more difficult to lock up OD. Is there an old program any where to be found, or can the shift curves be adjusted. Looking for help on this one, talk to me?
