Ceratec with oil change
Tomorrow I will give my C63 an oil service, as the manual says that the motor needs 8.5L oil I have the following question. I will add 2 cans (600ml) of Ceratec (for the first time) in combination with Liquimoly 5w40 oil.
1. Does that mean that I have to fill the oil till 8.0 liter with liquimoly oil and then 2 cans of ceratec 600ml is together 8.6L?; or
2. Fill liquimoly oil till 8.5 liter and then add 2 cans of ceratec 600ml, together 9.1 liter?
Please let me know, because it is the first time my engine gets the ceratec after reading all positive comments on this forum about that product. Of course I will give the engine also an ''engine flush'' treathment.








I'm probably crazy.




Don't completely fill with oil first then add the Ceratec/MOS2 or you will overfill.

2 bottles of ceratec is something like 1 quart. proceed to add 7.5 quarts of oil after the 2 bottles of ceratec. if you are completing a total fill of 8.5 quarts. also, make sure you drain your oil cooler.
fyi, the W211 E63's take 9.2-9.5 quarts of which i fill my engine to. the updated M156 dip stick registers 8.5 quarts when full which i ignore.

Did yesterday the oil service with an engine flush first and then Liqui moly 5w40 + 2 bottles Ceratec. Good combination, engine runs fine and smooth. For the next oil service I should only add 1 bottle MOs2, no more ceratec right?








1. Don't flush as any built up crud can dislodge and block the finer oil galleries .
Shouldn't need it anyway .
What does Ceratec do ?
What is the MB oil spec for the C63 ?
