This maybe in theory, however be careful as that is rarely the case.

Example is Redline Diff Oils

75W85 @ 40deg C cSt = 68
75W90 @ 40deg C cSt = 112
75W140 @ 40deg C cSt = 179

Naturally every oil blender is different.

Re: Jeep service costs

Hi all, I've got a MY2014 Laredo CRD that we bought in October. The dealer sticker on the windscreen says first service is at 5000km. That's not normal is it? We're nearly at 5000km now. Isn't this thing supposed to have 10000km servicing?

Re: Jeep service costs

There is a 1,000km checkup that only some people have done or were told about. Aside from that it is 10,000km service.

Re: Jeep service costs

Yes, definately 10,000km is the next service.

Re: Jeep service costs

thanks guys, I won't be taking to them for a 5000km service then and paying money for no reason. The 6 month interval will likely be up before we do 10,000 so we'll get it serviced then, in about March.

After ringing 4 Jeep service departments in Sydney, I have 4 different recommendations as to the correct diff oil to use:

Dealer 1) 75w85 in the front, LS90 in the rear

Dealer 2) 75w140 with friction modifier front and rear

Dealer 3) 75w90 in the front, 75w90 with friction modifier in the rear

Dealer 4) 75w85 sounds right. No friction modifier in the front. Check on the Castrol website and go with what they say. Vehicle takes 6lt of diff oil - 3 lt in each diff. (Not according to the WK2jeep website it doesn't)

I reckon if I rang another couple I still wouldn't get the same answer twice. The only thing I can take from this with any certainty is that none of the dealers are using the Mopar oil listed in the owners manual.

Re: Jeep service costs

Did you try Jeep Customer Service in Melb?
They would probably tell you something like " Use oily stuff "

Close, they said to ring the dealers because they have no-one there with technical expertise.

Mind you, it didn't sound like dealer 4 in my previous post had any idea either.

(That is the dealer you take your JGC to BTW)

You get full marks for perseverance, and thanks from me…..i don't think i would have sufficient tolerance.
I'm sure you are right in that no dealer (OK there may be a rare animal out there), is using anything remotely like the correct Chrysler spec oil for the diffs (o sorry, we don't know what that is either!).
No surprise after researching what dealers are putting in as engine oil - regardless of the Chrysler spec.
I've come to believe that the quality Redline 75W85 previously mentioned or the Mobil 1 LS75W90 should be fine for the job. Certainly it will be a better option than letting my local dealer "just change the oil".

I also contacted Redline Australia to clarify which oil they recommend. They actually sound like they know what they were talking about, as opposed to the service departments I spoke to earlier. They do not recommend 75w85 for the JGC. It is too light for the JGC and does not provide sufficient protection in their opinion. They stated that manufacturers tend to specify the lightest grade oil they can as it will marginally improve fuel consumption figures. While the difference is not noticeable in the real world, the better fuel figures look better in the published vehicle specs.

For Australian conditions they recommend 75w90 at a minimum, with either 75w140 or 80w140 as their pick. The first figure is largely irrelevant and only makes a difference at sub-zero operating temperatures. The 140 grade provides better lubrication at higher temperatures as experienced in Australia, or heavy duty applications such as towing or off-roading. They recommend 140 grade for both diffs.

They also mentioned that they recommend 5w40 engine oil for the CRD but advised to use 5w30 as specified in the handbook to comply during the warranty period, even though they stated 5w30 is too light for the vehicle.

As an aside, they asked me where I purchased my Redline gear oil from and advised that they provide no manufacturer warranty for any products bought from GL Lubricants who are a grey importer. (I suspect the same holds true for Mobil, Royal Purple etc) GL Lubricants however, claim they have no liability for any product bought from them according to their website. I checked and at the foot of the homepage in 6pt grey type that is barely noticeable is this disclaimer:

Disclaimer: We, as GL Lubricants Pty Ltd, will not be held liable for any manufacturing defects or non-performance issues of the products we sell.

Something worth considering when purchasing from them and contrary to Australian Consumer Law.

The last dealer I spoke to actually admitted they service 8 brands of vehicle and dont carry seperate oils for each, so I guess that they would have a couple of 44 gallon drums of different engine oil grades and some generic gear oil. I figure the best you can hope for is that you at least get a 5w30 engine oil suitable for DPF.

Let's face it, 99% of customers wouldn't question what oils and lubricants are used as long as the dealer stamps their warranty book.

Re: Jeep service costs

I guess this is why many of us like to change our own oil.
