Hi All,

Can someone direct me to the correct rear end final drive oil to use in my differential? JLM21847 (75W-140) or C2D3650(BOT 720)?

Thanks!

 

Service manual calls for M2C 192A Synthetic which is a 75W140 synthetic gear oil but I don't know if it has friction modifiers

75w-140 GL5 gear oil - I use Amsoil 75w-140 severe gear oil. There is no drainplug, so you need to either split the diff cover open or vacuum / suck out the old diff oil which is what I did.

 

no. friction modifiers are not required in that diff.

 

A few photos and description of my differential oil change experience are in the attached link.

Thank you Stuart for posting the summary of 4.2l fluids and routine maintenance parts. Very handy!

 

I went with two o these:

There's tons of options out there, Liqui Moly is acceptable, among many others. I've used the DSG fluid, diesel purge and several others products from them in VW/Audi cars, and bought from FCPEuro many times; so I went with them and it's been uneventful since the change 10k ago in my 07 XKR.

 

Just a note that the first 2014 url (https://www.jaguarforums.com/forum/x...s-list-122939/) in post 1 says that the ATF in the ZFhp26 uses Shell 1374.5 (true) and Dexron III (not true). Most folks know this by now, but don't want newbies to be led astray. There are Shell 1374.5's out there, including ZF's LG6, and a Ford variant, but Dexron III isn't one of them. If someone has a spec sheet from ZF that says Dexron is acceptable, please post it.

Yep agreed. The guy hasn't been around since 2015 and although he said it wasn't a typo and even though this thread is about Differential oil, I'm going to add a comment to start the ATF wars, but really as Panthera said, correct some ATF info stated in the 2014 thread linked above:

Shell Spirax S4 is compliant with M-1375.4. Shell makes M-1375.4. We all know that.
Shell Spirax S4 also meets requirements for Fords requiring Mercon SP type aka, Ford Type D fluid.

Dexron III was compliant with Ford built between 1983 - 1996 where Mercon Performance was called for and specifically should not be used where Dexron® VI, Mercon® V or Mercon® SP are required. Not that hard to google this stuff but maybe there was less info on the inter web back then:-). That info is from Castrol.

 

Thanks! I see the note..

Differential, Rear......GL-5
All TEMPS......75W-140
80W-140 Synthetic Long Life Gear Lube

Does Jaguar have a released part number for the 75W-140? I have had two different places recommend either JLM21847 (which looks to be a 75w-140) or C2D3650which is "BOT 720" and is released for almost all older style cars (X100's X300's, 308's, including the F-type.. ) kinda scratching my head what this fluid is.

 

Certainly no interest in that discussion anymore, I hope. We beat it to bloody death on the BMW forums, certainly, as I assume was done here as well.

Kind of like starting an oil thread.....

Cheers---
