Sounds contradictory to me that it's ok to deviate from manual for LD oil for warranty but not engine oil.

Thanks for sharing the results of the efforts that you have put into this today, much appreciated.

It's interesting that the Redline Web site in the USA do specifiy 75W-85, however I take Redline Australia's point re the elevated temperatures here in Australia. I would have thought that parts of the US get quite hot as well, but probably not to the same extent as Australia.

I wonder what oil the JGC's have in them for a factory fill? I suspect the 75W-85, but we will never know.

I still believe that a quality 75W-85, combined with the "too frequent" diff oil changes that are specified by Jeep Aust would be OK for for normal use. Let's face it, most of these vehicles will never see off road and are really glorified shopping trolleys.

However if you do a bit of towing or plan on long road trips in the middle of Summer, then I think that 75W-90 is the way to go. Incidently, 75W-90 is not just 12.5% thicker as some people might think, it's actually about 50% thicker. A point to note thate these diffs have aluminium casings (with cooling fins from memory), and are not the old steel casings of yester-year. That will likely also help to reduce heat buildup.

So for me, as I do some towing from time to time, will probably go with 75W-90 next diff oil change. I'm just not comfortable with putting in oil that is too thick in these diffs if they have been engineered for 75W-85. I want to be sure that the oil is getting into those bearings very quickly when cold. (The "W" or winter viscosity of oils varies significantly when the "Warm" viscosity is altered, even if the 75W is the same).

In some ways, this conversation is redundant for most because a lot of original owners will likely change vehicles either near the end of warranty or 3 to 4 years when their lease or finance is up, and the reality is that no matter which oil of those discussed up the page is used, the vehicle should get to the expiration of warranty.

However there are those of us that keep their vehicles longer. We usually change our vehicles about every 8 to 10 years, depending on how well it is aging mechanically, so we like to get these sort of details right.

I do agree with Redline Aust re the engine 5W-30, and if I can get a low ash 5W-40 (by low ash I mean 0.6% by weight, not 0.8% as some so called low ash oils have, don't want to have to pay to replace that DPF anytime soon!!) that meets all other specs, then when the vehicle is out of warranty, I also will move to that. After the vehicle is out of warranty I will also be happy to ignore the Chrysler MS-11106 spec.

I take your points Swampy, which are well made. I was leaning towards 75w90 but after speaking to redline, I am going to use the 75w140 I bought for this service. Worst case scenario, I would rely on the wording of the owners manual which specifies 75w140 in the unlikely case of a warranty dispute. The reality is that if the 140 proves too thick I would drain it out and use 75w90.

I normally change my cars every 3 years but intend to keep this vehicle for much longer, so I want to make sure it is serviced correctly with the right parts and lubricants.

Agree with most of what Redline says. Also the addition of a friction modifier adds a safety factor. I would use the same friction modified oil front and rear. No sense in buying different oil, unless money is an issue. The issue of the engine oil I'm not sure about. With the tight tolerances of modern engines, the additional lubricity of the thicker oil can be offset by its inability to get into tight spaces, or so I've read. This is not a issue with diffs which are chuncky beasts.

Naturally every oil blender is different.
Too true! Also it depends on what one calls cold. 40C is pretty hot for most people whereas the SAE 75W test is carried out at -40C. No doubt they had a North American winter in mind.

Agreed. However Oil viscosity differences for "W" Winter usually widen as you get colder. At least the warm side of an oil, i.e. XXW-90 that has different Winter values usually stays about the same.

Re: Jeep service costs

Guys, this post has a tremendous amount of good info, good that we all seem to be around the same kms and can share excellent researched info to help the masses. I for one really appreciate you sharing your knowledge. Just on the front and rear diff, (bit confused especially with inacuracies in the manual), on a 2012 CRD Overland, do I go friction modifier front and rear, or just rear. I intend to carry out this oil change myself (using a 75W90) straight after the 40k service this week. Not sure if I have quad drive or quad track...ELSD etc. Any guidance is appreciated

Re: Jeep service costs

Hi Glenn

Overland should have the Quadra-Drive.

Friction modifiers are only technically required for the rear ELSD but can go in the front, no probs. The reason they specifiy that friction mods are not required for the front is that it can be slightly cheaper.

Just be sure the oil is GL5.

Re: Jeep service costs

Just about everyone has their own favourite in regard to oils. The reality is that a lot of the same spec oils from different blenders have the same base stocks and each blender adds their own mix of additives.

Personally, I'm running Redline Oil in the diffs, but can be hard to get hold off and a little pricey. However Penrite would be my second choice and I use that in my other vehicle which is a conventional sedan.

Both Redline & Penrite have Gear oil products whose synthetic base oils contain PAO and Esters, which are pretty much top of the Wazzer in regard to oils. (How much they include, who knows?).

I have never used Nulon however I do recall a fellow Member Enforcer who liked the Nulon products, not sure about the Gear oils though. He may read this and make comment.
