C55 Alternative Brand Differential Fluid?
For those who have experience with other brands what is your feedback?
What is the Mercedes brand fluid? Castrol?
Thank you.
The change interval is dependent on the temperature and conditions that the differential is exposed to.
If one drives their car hard a lot and the fluid gets a lot of heat it will need to be changed more often. These fluids all pass a SAE test that consists of different categories but I know viscocity breakdown over time due to heat is one of them.
