I hope there are many more who can say their CRD's do as well.

Did change my oil today at 2380 mi. 8 mm allen wrench on the drain plug surprised me. Used Mobil 1 0W-40 from WalMart at $4.86 a quart and a NAPA Gold #1516. And yes, I changed the air filter too. The K&N is on the shelf. Got a WIX. The original factory filter had info on it I'd like to check with that filter testing guy. It said 98% efficient, 130 grams max dirt and 0.035 bar pressure drop. WIX had a dozen or so more pleats and each pleat was a bit longer. Tried for an A/C but the A/C warehouse didn't list the number y'all had for it. Got A/C's for everything else I own.
It was fun. The bottom of my Jeep is cleaner than the top.

I know this is the right way to do this because DC replaced my Caravan with 21,000 miles at a cost of $12.00 for me. Never once did I expect such respect, kindness or think they (DC) cared about what customers did with their problems. This made a believer out of me!
I wish you well, but remember not all of us agree on which truck is better than another, perhaps you will find the Chevy forum more informative at this point and time for yourself and us who like our CRD's. Thank you and good luck.

You are right. I would never take a loss on a new vehicle like that. I would have dogged everyone involved until they screamed uncle. Losing that kind of money goes against all my moral principles. I have followed this thread from the beginning and realize you guys have had some issues. I appreciate those that are taking on a new vehicle. I am hoping they bring out the Wrangler with a CRD it should have most of the bugs worked out as a result of your perseverance. Also by then the diesel across the US should be much better for the CRD to live with. Good luck to all of you Jeepers. I miss my old CJ3.

The passenger side tab slot that holds the air box cover on was boken - three of four tabs hold the cover on. The cover continues to want to lean rearward against the intercooler hose and getting close to the vacuum filter.
Lost poster alljeep just reported the same thing.
I suspect too much weight/stress on the cover with nothing substantial to secure the bottom of the airbox.
Donaldson, afe, amsoil, somebody give us a cold air so we can replace this junky setup.

At work, we're concerned about our diesel's and have monthly samples sent to Southwest Research for analysis. Our engines are running Mobil 1 15W-50 and it's almost 10 years since we last changed it. BUT we're talking a 800 gallon oil change and a 5,000 hp diesel.
A lot of regular oils are now "Group II" or "Group III" base stocks. Very highly refined mineral oil with the oxidation stability of the synthetics. Synthetics earn their pay in the "extreme pressure" category (keeping metal away from metal under pressure like at the gear teeth and piston ring to cylinder bore and piston wrist pin areas.
Regular Penzoil, Chevron, Citgo engine oils are Group II/III. (Castrol went to court to get to call these Group II & IIIs "Synthetic".)
ALSO you can run oil longer now because fuel is much cleaner than in the '70s AND combustion is controlled much better. (Some changes to cars to get cleaner air have helped the engine.)
Oil change intervals should be based on the rate of build-up of "pentane insolubles", time to breakdown of oil viscosity and additive life. Oil sump capacity is supposed to be sized on this (then on the next even size of oil container?)
If you have to run synthetic in a car, that'd be like having to run premium fuel in it to me and would be an objection to overcome before I'd buy the car. A 15,000 mile change interval might be enough to convince me to use the expensive oil. 30k would be better. :shades:

It is possible to get 600 miles on a 20 gallon tank of diesel driving 65 MPH all highway on cruise with minimal stopping in warm to hot weather, #2 diesel fuel, no head wind and nothing is wrong with the vehicle. My personal experience is that 800 miles on a tank is impossible and 500 miles is more likely. My overall fuel economy since new is 24.4 MPG 50/50 city/highway.
Expect 3 MPG lower fuel mileage on winter fuel.
I was hoping that someone, other than caribou1-who mentioned the airbox months ago, would look at the airbox.
There seems to be 2 issues.
The plastic inlet tube attached to the radiator mount is too long and/or too hard - it pushes the airbox rearward. Cut the tube and adapt real flexible tubing or do away with it entirely and get some hot engine air and and hopefullly no water in the box.
Secondly, the air box top does seem to be too tight for the filter or the tabs too weak, we all know the crd and the gassers use the same air filter.
I'm on my third dc filter. With 4,000 miles on the newest, it looked like it was a secondary ccv filter with the turbo backflushing crap into it.
Filter flow vs filter resistance links here. Out of frustration, yesterday I bought an eight dollar cheap paper air filter from O'reillys and took a road trip today. I felt the thinner paper let the diesel breathe better. I made the same mistake dc did, changed more than one variable at a time-new thin air filter and the aero-turbine muffler.
2200 to 2600 rpms and 25.8mpg's.
I am also interested in the manual.
Anybody use it?
Thanks

My commuting mileage during the past year went from 10.3L/100KM to 12.2 last week (20~% worse).
I came across a recent Renault service document that stressed the need to clean these valves as soon as possible because they were having too many problems only related to the EGR.
I disconnected mine, and BINGO
The engine runs like when I first bought it, mileage is back to normal, shifting between 4th and 5th is sharp, when in overdrive at 60 mph acceleration is instantaneous when I need to overtake traffic.
This valve comes into play at around 1600 rpm and below 2500 rpm apparently. It stays closed at idle speed and under load. Mine definitely delayed to close the circuit and this affected turning off the engine as well as acceleration. When I turn off the engine now, it instantly stops :shades:
Driving in heavy traffic is easier because shifting responds to my toe. What a difference !!!
Now my question: could this be the cause of the erratic shifting some people mention here?
Renault/Nissan owners report a lack of power in the 4th and 5th gears, but never in 3rd. When we lock out the overdrive, we are in 3rd gear.
You'll have to ask yourself what kind of driving will you do?...
Do you travel far distances? and towing?
I would suggest the "diesel liberty",just because it would out perform the gas 3.7L in mileage alone.
3.7L =350 miles /tank 22mpg/hiway typical sport $29 000ca
2.8L =500 miles/hiway 27mpg/Sport Diesel $34 000 ca
You can get the diesel Liberty in the sport package ,and save yourself $4000.Compared to the LTD .Unless you like heated leather seats and want to impress "Les Femmes".
But I would at least get the class 3 ,2" inch sleeve hitch
and 1,7/8" ball for most boat trailers,and make a deal with the dealer to trade in those crappy Wrangler tires they put on,and get some half decent All terrain T/A's ,because you'll most definitely will need traction ,there in Quebec.
Michelin makes an ATS and an LTX M/S that is reasonable .
B.F Goodrich all terrain T/A KO is the best grippy tire you'll find,but expensive.
You'll love the 4X4 in the liberty and the room inside compared to the little VW's is nice when you take out friends .You don't have to cram into a small car anymore,and get decent mileage,plus a multi purpose vehicle that is comfortable on the hiway.
A prochaine...

With the air outlet in the lid, a cold air tube probably will never be made by an aftermarket company. There is a lot of tension from the outlet tube on the bottom of the airbox. I don't know if dc is going to help with the small number of kj crd's-my bet (and I should've listened to that mature mechanic at the selling dealership) do you want to be a guines pig. I think we are orphaned. The vm motor in the small kj engine compartment is a disaster. I'm going to lurk off roaders and try to find an airbox answer-any help here or from lost members will be greatly appreciated.

Was wondering if anyone else has it and if the claims are true or not. Thanks for any imput. I'm always skeptical of user "reviews" on a product's webpage. The forums here seem to be the best for finding the truth.

If the CRD is set up to use ULSD, then a sulfated ash of 1.6% is on the high side. The Mobil 1 0W-40 and Delvac 1 5W-40 have polyalpha olefin base stock and sulfated ash of 1.2%/1.35% respectively (both blessed by Daimler Chrysler/Mercedes 229.3 and 228.5 respectively.) Back when I got my Cummins powered Dodge 1990, I bought Cummins Premium Blue. Then came the semi-synthetic version. My company's oil jobber had a drum of it in the corner. They said the additives had separated out. I'm sure Valvoline has fixed that problem.
The sulphated ash number comes from "ashing" the oil and treating it with Sulphuric acid. It measures the calcium sulphonate (TBN, anti-acid), ZDDP and other additives that have minerals that don't burn away like the hydrocarbons do in the combustion chamber. The oil that gets past the rings and valve stem seals carries the TBN to counteract the sulphuric acid formed when fuel sulfur is burned. Too much unused TBN ends up as deposits on your piston crowns and ring grooves.
Chevron has the same base stock as this Valvoline, calls it ISO-SYN and has worked to use hydrocarbon based additives rather than ash producing. I like the Chevron Delo 400 line if not using the Mobil synthetics.
Long live the CRD! (so Steve won't run me off to the other forum)
