2018 Mercedes C63s Coupe
Differential Service Oil
Hello. I have a 2018 pre facelift C63s Coupe and due to the car being modified and me driving it hard im doing the 30000 mile transmission and diff service early. I got the parts for the transmission maintenance easily but im a bit confused on which oil to use for the differential. When i asked at a mercedes parts store here in my country they said that using my vin the oil that the system tells them it takes is 75w90 GLS but i've seen some places online that i should use 75w140. What is the correct oil type and how much do i have to buy? Thanks in advance.

They'll give you a list of approved fluids and you can take advantaged of their "lifetime replacement guarantee" which does also apply to fluids. Buy new fluid, change said fluid, and when it comes time to buy new fluid again, ship back the used old fluid (the one originally purchased from them) and get a full refund as store credit.
