Are any of you guys running a standard synthetic 75-90 or does everyone run the Mercedes fluid in the NON limited slips diffs? I have a CL55 that I'm going to do the fluid in tomorrow and would like to hear a few different opinions.

If I remember right Mercedes calls for a 85-90 Hypoid. Let me know if I'm wrong.

 

I use 75w-90 royal purple. Never had a problem.

 

i just bought an lsd from jerry at EC...its being shipped but i am curious as to what others are doing, diff lub????... doing a tranny service next week, you boys what inexpensive oil Shell ATF 134

Will this do on an SL55- 75-90

I was going to do 75-140 but why I don't have LSD..

FCP Euro keeps suggesting 75-140 otherwise and so does every other site..

 

I use the Hypoid gear oil SAE 85 W 90 that MB recommends

 

Thank you, searched showed half the e55 guys using 75 LMAO!

Apparently the 85 isn't synthetic -https://www.fcpeuro.com/products/85w-90-hypoid-gear-oil-1-liter-lubro-moly-lm1035

While the 75 is -.-

 

So 75-90? How much does the diff take? I am going to do my diff and the transmission in the spring. Called around and the dealer wanted ~$900.00. Uh no.

 

I'm reading a lot of 85-90 as well. Apparently alot of AMG owners review's on amazon and 85-90 is 9$ for 1 liter(we need 1.5) on FCP...LiquiMoly is the only supplier for this available.

I think I'll do 85-90..

Let me know if you find anymore info.

Same here with the Spring maint.

 

I used the same stuff the M5 guys did. I looked up the sauce for the limited slip E63 and its the same stuff.
