I know for engine oil, Mobil 1 turbo diesel truck seems to be one of the most popular (I use it myself). For antifreeze we need HOAT coolant. Zerex is what I have and I believe is the most common.

What do you guys use for other vehicle fluids? Transmission? Front axle? Rear axle? Transfer case? Do you pick something that meets the owners manual specs or is there one that seems to work best?

I use Rotella T6 for oil, it's usually cheaper and I've had good luck with it in all my trucks.

My neighbor who owns a transmission repair shop and drag races likes Schaffer products for driveline fluids.

Im not a brand loyalist.

For engine oil, either:
Mobil 1 TDT 5w-40
Shell rotella T6 5w-40
Delo 400LE 5w-40

For coolant, Zerex G-05 is the only HOAT I can find locally.

For the diffs, I have Richmond Gear synthetic 75w-140 gear oil.

For the trans and transfer case, ATF+4 only.
This is the best deal I have found https://www.amazon.com/dp/B00M1Y3NL6/ref=twister_B00XY8XNXG?_encoding=UTF8&psc=1

I agree, best GEAR oil, for front and rear Diff. It may be fine for transfer case also, but I'd stick with atf+4 for that.

Mobil1 TDT or Rotella T6, whichever is cheaper. Usually that's the Rotella T6, but at one point Autozone had the M1 on clearance for like $5 a gallon or something stupid. I bought 20+ gallons which held me over for a long time. Everything was very clean when I removed my intake manifold and the stock rockers felt very good.

I have not done the trans yet, but I just bought the Supertech ATF+4 from walmart. Would probably do the same for the diffs and transfercase(supertech i mean).

I use Shell Rotella T6 5w40 for engine oil. Zerex G-05 coolant, I for the Differentials I don't remember what brand I used, I think it was Valvoline that the store had in stock. I don't think it matters what brand, only that you use the correct weight gear oil for each.

For transmission fluid I have used or topped up with many brands and that is not supper critical just be sure you use ATF+4 and that it is an approved FCA licensed brand from this list:

Use an engine oil that is engineered to meet Chrysler's MS10725 specification. That is what the manual stipulates, and given the problems this engine has had with valve train issues, it would be foolish to use anything else.

Amsoil will have a diesel engine oil with an additive package that meets this specification, and the prices are reasonable. I am uncertain if either Shell Rotella or Mobile 1 has an additive package that meets this specification. All engine oil manufacturers have toll free technical help line numbers so you can call them and ask if the oil you are thinking of using has the appropriate additive package to meet the MS10725 specification.

Using an engine oil because it works well in other engines is NOT a good reason to use it in the CRD engine. Basing your decision on price alone is also foolish. The R428 engine that powers the CRD is a completely different animal than most older domestic diesel engines and is subject to conditions like the ridiculous pollution control standards that most diesel engines over 10 years old do not have to endure.

What many people don't know about Shell, is that they make and sell TWO different Rotella T6 Full-Synthetic Heavy Duty 5W-40 engine oils for turbo diesels.

One Meets API CJ-4 PN# 550019914 This is the one many people continue to buy because of it's lower cost. This is not saying it's a bad oil. It still meets or exceeds the requirements of our R428 VMM engines. (CI-4)

One Meets the much more stringent API CK-4 PN# 550045347, and is compliant with all current tight-clearance, low emissions , and previous models of TurboDiesel engines. These are currently heavily discounted at Wal-Mart online, and at Amazon.

By law, (at least in the US) Engine oils must be API backwards-compatible, OR, If they are not, it must be clearly stated.

There is more than one specification to meet, GordnadoCRD.

CJ-4 and CI-4 only speak to the general classification of the diesel engine oil and how the designation changes with the advancement of lubrication technology over time. As time marches on and there are general advancements in engine lubricants to deal with the greater demands put on engines, so goes the advancements in API Engine Oil Lubricant Specification. CG-4 advances to CH-4, which in turn advances to CI-4, then CI-4 Plus, then CJ-4 and now CK-4. Please see the following link...

http://www.oilspecifications.org/api_eolcs.php

These designations do not deal with the specific and unique requirements of the R428 engine in the Liberty CRD. This is the case with many internal combustions engines and is the reason why you will see more than one specification on any given container of engine oil. The owner's manual and the factory service manual specifically state that the CRD engine must have engine oil that meets Chrysler's MS10725 specification. This is in addition to and regardless of the basic diesel engine oil specification of CI-4 or CJ-4. MS10725 probably is a special additive package required for the unique challenges the R428 engine has to face, especially here in North America.

MS-10725 is an obsolete specification. (CI-4)
Until Jxaxnxuxaxrxy CURRENT DATE of this year, (my mistake, the new one hasn't been published yet) it remains, for 0W-40, MS-12633. (CJ-4) Until the new one is published.

Put shortly, both types of Shell Rotella T6 meet and exceed MS-10725, as well as MS-12633. (0W-40)
MS-10850 is the spec for full synthetic 5W-40 of CJ-4 quality.
MS-10902 is the spec for full synthetic 15W-40 of CJ-4 quality.
MS-11116 is the spec for full synthetic 5W-30 of CJ-4 quality, suggested for the 3.0L V6 CRDs.

The "specification MS-10725" is, in a nutshell, best currently available (at year of manufacture) full-synthetic 0W-40 weight, Multi-fuel (CI-4 / SL), engine oil. Since the latest API specifications were introduced through legislation so recently, FCA are most likely holding off until YM 2018 vehicles or later to publish the new oil spec.

While what you say regarding API classifications is technically true, In this instance, MS-10725, or any other current or former "Chrysler" (FCA) specification doesn't refer to any particular additive package. They just re-package the specification of the best current API classification, and put their own title on it. (MS-12633)

I been looking and I am not finding current oils that are available at mass market or auto parts stores that are rated ms-10275 for diesel engines. closest so far I found is this Penzoil product that meets a newer Chrysler spec and can also be used in SRT engines that require ms-10275. the thing is SRT engines are not diesel they are Gasoline.
http://www.pennzoil.com/en_us/products/full-synthetic-motor-oils/pennzoil-ultra-platinum/_jcr_content/productDetails.stream/1460058459415/cbaf42eae4dcbcd08bee4f669a8ee71a73584bf793056ec459c9cdd99445c116/Pennzoil-Ultra-Platinum-0W-40.pdf

I searched Mobil one's web site based on our make/model/engine. this was the result:

"Based on what you've told us, your vehicle manufacturer recommends a 0W-40 or 5W-40 viscosity and oil that meets Chrysler MS-10725. We currently do not offer any motor oils in the United States that meet these specifications."

The Chrysler/FCA MS-10275 spec is out of date, has been superseded by newer spec that is not related to diesel engines so I don't see how it really matters like it once did. the oil I use meets newer more stringent specs than the oil they originally recommend in the owners manual. Rotella T6, M1 turbo D truck, and Dello 400 LE are all good.

I see an oil war starting here again..... so

O.K.... Message understood. I thought the designation was for an engine oil with a special additive package.

I can understand why Chrysler and FCA would do this as it puts all of the specifications of a particular engine oil into one number for the customer to remember.

You are seeing mirages, mikey1273. I am not arguing with GordnadoCRD about what oil to use. This is merely a clarification of what MS10725 means.

Folks why are we spilling "ink" on the oil topic arguing about the meaning of what the Owner's Manual says. It was written 10+ years ago calling for "Engine Oil Viscosity (2.8L Diesel Engines ) Use SAE0W-40 Synthetic Engine Oil that meets API categories SM and CF (SM/CF) or better and the requirements of Daimler Chrysler Material Standard MS-10725. If you cannot find SAE0W-40, then SAE5W-40 Synthetic Engine Oil is acceptable." Please NOTE the "or better". The SM rating is irrelevant as it's for gas engines and the diesel CF rating is a 1994 standard suitable only for diesel with over 0.5% weight sulfur NOT ULSD which is the only diesel you can legally buy in the USA after October 2006.

It's self-evident and no surprise that DCJ simply copied and pasted old oil specs into the CRD owner's manual as the 2005-06 oil specs should have called for oil meeting CI-4 specs that were introduced in 2002 for ULSD and engines with an EGR systems. Per API the CJ-4 and CK-4 are later oil specifications and are backward compatible hence perfectly suitable for use in the CRD per the "or better" standard of the owner's manual.

As near as I can tell Shell does NOT currently make 2 versions of Rotella T-6. Shell used to make a CJ-4 version (what I bought in 2015 from Amazon) which may still be on some shelves (apparently not Amazon) and possibly discounted in price. That has been replaced with a CK-4 version. Both are blue bottle but different shades of blue and both are ok for the CRD.

Anyone that wants to try and find CF oil and use that out dated spec oil in the CRD is free to do so at their own risk. While I no longer have my CRD, my son has his, I cannot recommend stepping backwards.

Here ends the rant.

You have stated that well and that was my point. current oils are better than the outdated specs that the manual recommends as long and you use diesel engine oil of 0w40 or 5w40 full synthetic. I am not seeing any Mirage, not even one by Mitsubishi. Chrysler MS-10725 rating is not listed on any current oil labels that I have found at retail. as said above CJ-4 and CK-4 exceeds the specs the manual calls for so that should be fine. saying it has to meet MS-10725, I don't think is important anymore. The only product that might still list ms-10725 on the label is probably Amsoil.

This subject has been discussed in great detail before and resurfaces from time to time as new members come on board!
Take aways: make your own decisions on what is the best oil for your vehicles based on type of driving, temperature conditions vehicle will be exposed to, and most importantly API ratings...
Here is some of the general discussions around this subject.

Mobil 1 0W-40 IS NOT AN API DIESEL RATED OIL!!!!!

See this Web page for API Oil Ratings:> http://www.api.org/products-and-service ... categories

It has NO diesel API ratings! It does not meet or have diesel CJ or CI ratings...

Mobil 1 0W-40 oil is rated: API SN, SM, SL, SJ
(all are GASOLINE engine oil Ratings!)

Mobil 1 Turbo Diesel Oil is rated: API CJ-4, CI-4 PLUS, CI-4, CH-4/ SM, SL, SJ
CJ, CI, & CH are all DIESEL engine oil API ratings!

Why in the world Mopar ever recommended a non API diesel rated spec oil for a turbo-diesel engine w/EGR system is ludicrous!
(No wonder many have had rocker arm/lifter failures!)

But if you need to know, this is the Mopar Specification that superseded it:
Keep in mind, this spec oil was listed for several Mopar GASOLINE engines!
Part No. - 68171066GA
0W-40 MOPAR® ENGINE OIL, synthetic MS-SPEC: MS-12633
Specifically formulated for the needs of Chrysler SRT engines where MS-12633 is required. It may also be used in SRT engines originally recommending Chrysler MS-10725
They no longer list the MS-10725 Spec on their "Mopar International - Lubricant and Chemical Cross Reference Chart"
It is an obsolete Specification!

A little more insight as to why Mobil 1 may not list the MS-10725 specification anymore:
May have been withdrawn due to a clause in their contract?
Apparently M1 0w-40 used to carry that spec in the US in the past, but no longer list it.

From another forum:
I do not believe this was Fiat's doing given that it still meets 3 Fiat specs. It has been mentioned this change took effect during Daimler's ownership.
This is possibly the result of a Non-compete clause that Chrysler placed into Mobil's Factory Fill contract.
Something along the lines of...In return for us extending exclusive use of your product in our vehicles, you agree, after termination of this agreement, to forfeit the marketing and/or approval of this specification, so that it can be exclusively extended to a subsequent party for X amount of years.


Use what you wish; I simply would never run or recommend a API non-diesel rated oil in my diesels or anyone else's diesel period!
The ratings are engineering developed standards and are rated as such for a reason!

Mobil 1 Turbo Diesel and several others including Rotella T6 all are good diesel oils with the correct API ratings...

We all have opinions and interpretations of all the available information!!!
But I do trust the API Ratings!
To each his own; I simply would never recommend Mobil 1 0W-40 oil to be used in any diesel engine when there are so many better choices of diesel rated oils available for the user....
