I am low on fluid, part number on the sticker says 124 584 4321 A however I can not find the fluid anywhere. There is fluid in the reservior however not enough to even though the little dipstick. Am I searching for this part number wrong?

The container usually had some form of green label which was the "code" for the mineral based oil. I know I have seem a Castrol version of this in a small plactic bottle at some Beck Arnley stores in Southern California. And yes, it is far more expensive than most other oils. I absolutely would NOT use anything other than a mineral based oil in these systems even if only temporarily. It won't take much to kill all your seals.

- Hydraulic Fluid Substitute for self-leveling suspension?

That same thread says that Haynes book suggests "Shell Aero Hydralic Fluid", any comments?

I think it uses that Febi(sp) Oil, it's available at the dealership, I dont know if you can use any other fluids though

You can buy LHM from Brad Nauss Automotive in Mechanicsburg PA. Or you can buy Kendall Hyken Glacial Blue, which is the same thing, from any oil supplier.

LHM++ is 16.00 quart, Hyken is 8.00 per gallon.

The basic difference is that LHM++ can also be used in aircraft hydraulics and it will not slow up too much at -100 windchill, in case you take your plane to the Arctic, like the Air Force does.

Hyken has worked fine with my cars and it can be added to LHM.

If you were close, I'd pour you a quart, I have 5 gallons.

@Aquaticedge - I have a feeling that is what the dealer would want you to think. =)

@Strelnik - 5 Gallons??? Goodness that is a lot of hydrolic fluid; no I don't think it has even been -1 in New Jersey since I have been around, so I am not too worried about LHM++ freezing (or slowing up).

How much did that cost you dare I ask?
I can't seem to find anything on it, what does LHM stand for?

Do you guys know how much they charge for this stuff @ the dealership?

Shell Aero Hydraulic is the same fluid Western calls for in their plows- Another potential source of the fluid?

Hi
In Houston, the dealer quoted me $30/ liter. Mercedes also approves Shell Tellus 15 (was called Tellus 17) which is about $70 for 5 gallons.

If you look a little closer at (that place in Arizona), you'll usually note the actual Mercedes part number listed.

This fluid is now A000 989 91 03 10 and according to

http://www.getmercedesparts.com

MSRP is $14 and their price is $10.50 (plus shipping) per liter

5 gallons is not a lot when you consider that I service other peoples' Cits and usually the cars need fluid changes.

5 gallons cost me 44.00 plus tax at Imperial Oil Supply, Pontiac, MI

LHM stands for: Liquide Hydraulique Mineral (French) or Mineral-oil based Hydraulic Fluid. This is the second generation hydraulic fluid following a synthetic or hybrid (with vegetable oil) version Citroen used from 1954-1968 in their cars and that Rolls used too in its suspension which it bought from Citroen.

It doesn't burn, doesn't attack paint, has a very high flash point, flows better at low temps up to -100 F, is not hydroscopic (attracts no water) and is not poisonous.

LHM has been around in a couple versions since 1966. It is not compatible with the earlier LHS. Cits and Benzes that use LHM use seals made of different polymers than vegetable oil cars (called LHS cars) which use seals made from EPDM.

Ask away I know a lot about this stuff, I have compared various fluids for quite a while in an effort to find one that matches all the tech specs like the Kendall Hyken does.

As mentioned above by lkchris the part number for the proper hydraulic fluid is A 000 989 91 0310. The Febi-Bilstein P/N is 02615 and it comes in 1 liter bottles. It is a special mineral based hydraulic oil that is unique to the Mercedes SLS system. The World PAC P/N is W0133-1635777 (Fastlane, etc.)

I'd like to see the tech specs on this stuff. I'd send them to independent testing engineer Mark Bardenwarper, who has been studying hydraulic fluid as a life's application. He can tell you more about that stuff than you would ever want to know.

He is also an amazing mechanic who gives away practically everything he knows, because he's tired of people being screwed.

Hyken Glacial Blu or Golden MV?

edit: Never mind, I failed to read the above...

frankstallone · #13 01-22-2010, 08:55 AM

@Steve - Thank you my friend for the current part #'s

@Strelnik - Do you want me to ship you a bottle of this stuff so you can have your guy take a look at it? =)

@Everyone - What happens when you are low on the fluid in the reservoir? Does the back sag? Does it loose it's ability to recover quickly after a bump? I realized I was almost 2 liters down! X__X

Whiskeydan · #14 01-22-2010, 10:53 PM

I wonder if a viscosity change will affect the dampening rate?

Perhaps the Golden MV fluid will provide a stiffer ride.

Pictures are always fun--Best OEM equivalent choice as Steve mentioned, any WorldPac reseller. (www.importeccatalog.com) 10.69 a liter
