I'm having a hard time finding out what the part number is for our LSD oil for the 09 C63. Anyone know what the part number is? Thank you in advance.

If the information was already posted, I couldn't find it in the search function...

rantarC63

I have searched for the same thing to no avail. Anyway, the owner's manual lists "Fuchs Titan EG 5010 D" as the rear differential oil for the C63 AMG but it does not specify if this is for LSD equipped cars or for non-LSD cars. A search for the oil revealed nothing so I contacted Fuchs directly and this is what they replied:

"The Titan EG 5010 D is sold as Titan Sintopoid FE SAE 75W-85. It was formulated for European applications, and so it was never tested in a full GL-5 program. The formulation offers the frictional properties required by MB 235.7 - additional frictional modifiers are not necessary. "

I sent a follow-up question about the PP equipped C63 to find out if it uses a different fluid as I would expect a 75W-140 oil in an LSD. Check out this post:

https://mbworld.org/forums/c63-amg-w204/255753-important-note-all-you-c63-pp-owners.html#post2983306

What this post says is consistent with the information posted here:

http://www.motor.com/product_updates.asp

The information on that site indicates that the LSD cars (other than the C63) use the 75W-140 oil whereas the non-LSD cars use the 85W-90 oil (a seeming inconsistency with the information from Fuchs but there may not be much difference between the 75W-85 and the 85W-90 - more research is needed). I would expect all AMG cars to generally use the same diff oil across product lines with a difference between LSD and non-LSD cars, however.

This site "http://www.minotek.com/lubeinfo/key.pdf" states:

"Mercedes-Benz: 6-Speed Manual transmission use P/N 001 989 2603 or approved products listed on MB Sheet 235.10. All others manual transmissions use as noted P/N 000 989 2603 or approved products on MB Sheet 236.2. Rear Differential 2008 S63 AMG and 2008 S65 AMG use Fuchs Titan EG 5010 D."

If the 75W-140 oil is the correct one for the LSD cars, I will likely use Motul instead of Castrol. See this link:

I'm still sponsored by Motul, so I guess I have to really ask which one is better... when I spoke with them, they didn't know which diff oil was correct. They were also telling me that they should have the AMG certified engine oil over here in the states early next year.

rantarC63

I decided to ask the dealer about this and after some back and forth (including them trying to tell me to put MB ATF fluid in the diff) they finally produced a document which listed the Castrol SAF-XJ 75W-140 fluid as the correct differential fluid for the C63 AMG fitted with an LSD. That is additional confirmation of what others have posted and I think the Motul Gear Competition 75W-140 fluid should work just fine.

hey bro, ur just on time information is really really helpful to me, coz i am going to bring my sweety to da dealer tmr, and i am gonna ask them wat type of oil they gonna use. Thanks alot indeed!!

paulGT3

The first diff change is under warranty right? Take it in and ask?
I think its at 1800 miles.

jackrycheung

yea, I think so, its about 3k

dlbello

Yes it is....

tazma61

Does anyone know how much is required...

My dealer said that the diff change is not covered under warranty, and it will cost me over $100, so I'm playing the waiting game...

AMGBeleza

I think the LSD oil in the C63 is the same as the CL63. The AMG LSD oil p/n for the CL63 should be MB A0019895203-0003. Hope that hasn't already been covered.

Edit: I will get an answer and make sure that it is the same p/n and will repost here.

rantarC63

I looked into the properties of the Castrol v. Motul oils and here are the specs:

Castrol:
Viscosity grade 75W-140
Density at 15°C (59°F) → 0.861
Viscosity at 40°C (104°F) → 177.2
Viscosity at 100°C (212°F) → 25.0
Viscosity index → 174
Pour point → -54°C

http://www.ge39.com/files/SAF_XO_SAF_XJ_B1174_96.pdf

Motul:
Viscosity grade 75W-140
Density at 15°C (59°F) → 0.906
Viscosity at 40°C (104°F) → 170 mm²/s
Viscosity at 100°C (212°F) → 24.7 mm²/s
Viscosity index → 178
Pour point → -36°C

http://www.motul-oil.co.uk/motul%20d...235%20(GB).pdf

See this link as well for diff oils used by MB:
http://www.billsden.org/fileadmin/me...ducts_2005.pdf

The numbers are close except for the pour point which is fairly lower for the Castrol. Any chemical engineers or chemists out there mind explaining these numbers?

As for the amount of oil, I would think it takes a liter at a minimum. The dealer also said that you had to put in the new fluid, drive the car (doing circle eights), and then top if off again. I've never heard of such a thing and don't put a lot of faith in his comments as he wanted to sell me ATF fluid. When it comes time to do my change, I will get the service manual for the procedure and find out what the correct procedure and amount is.

Straight from AMG/MB:

"In response to your inquiry, Motul Competition Gear is not approved by
Mercedes-Benz.

The MB recommended differential fluids are:

Castrol SAF XJ 75W-140
MB 235.61 AMG Hypoid Gear Oil 0019895203 75W-140

The fill capacity is 1.2 litres."

I just got my diff fluid changed today and they charged me about 200$ or so

.. has anyone else is Canada received this free?

jackrycheung

yea, mine is even more, he said around 300 bucks, I am going to do it tmr

rantarC63

I just paid $21 for each 500ml bottle of diff fluid so that should give you some idea of how much the materials should cost ($63 for the 3 bottles required).

I refuse to get my work done at the dealer as they always screw something up and are overpriced but some folks have no decent options. I am lucky to have a good shop nearby that has the most meticulous mechanic I've ever met. Just wait until you do your oil change at the dealer and pay another $300 for that (filter is $22 and a quart of oil at PepBoys is $6.70).

AMGBeleza

Yes, that's the right part number. Same as I posted before.

Glock Guru

Mine was free, both times (see 2000k service post)

Java

fyi,
Had mine done today
what it says on invoice
I called the dealer in advance to inquire abt the drain plug. They had to order it

Part # / Description / Price
3 001-989-52-03-10 Transmission 72
1 001-990-23-17 Piston 22.50 (drain plug?)
1 002-989-23-71 Adhesive no charge (no idea what this is)

labor $ $115.00
with tax and Hazz mat,
total was $230.32

Strafe1

Paid $143 USD. Got the Castrol (3-1 litre bottles were used), drain plug replaced, fill plug replaced (had to be ordered from Germany ahead of time). Not covered under warranty. Expect to pay, but it looks like someone got the service for free in Lousiana?

I went through all this on my E63 with Performance package.

Castrol SAF-XJ 75W-140 is the only one that does not void your warrantee.

It should be serviced for free at your first visit. I went through this with my dealer because I did he change myself before I found they should have done it. In the end the comp'ed me an A service.

There are only 2 sources for this gear lub.
1. Mercedes dealership
2. BMW dealership.

I got it at the BMW dealership because it cost 1/3 that of the MB dealer. You just need to bring your own container. Now I have enough to change it again.

For those doing it themselves, it is a 17mm hex and takes about 150ft lbs to break free. I did not use new plugs, and I have had no drips or weaping. I did put a little silicon sealer on the threads.

BSinSTL.

Could some one tell me where to find some official numbers or
document from MB or AMG on this LSD oil.
I showed the dealer the post from rantarC63,
of course not a problem they tell me.
Well picked up the car today and they charged me $4.80 for gear lube and
$63.48 for labor.We all know they put the right stuff in it,cant argue with
stupid.
Thanks in advance for all your help.

I'm going to do the diff service myself since the local dealer told me it would be over $300 for them to do it and that it was not a complimentary service. I talked to the parts dept and they need to order the drain plug for me. I'm assuming that the drain plug and fill plug are the same so I need to get 2 of them. Can anyone who has had this done or done it themselves verify that the drain and fill plug are in fact the same part # and that you do replace both of them.

Thanks,

Mike

Oftopic. I have a 08 and it has a self lockig diff the dealer don't change my oil on the diff but my owners manual saying to change it? I'm lost here and well over the 1800 mile. LOL thanks

I just bought the Castrol SAF-XJ 75W-140 diff lube today at the local BMW dealer as was suggested by a post I saw on this board. The price with my CCA discount was a little over $10 per .5l. About 1/3 of the price the MB dealer wanted. For anyone else doing this fluid service on their own, I would definitely recommend going this route.
