Follow the manufactures recommendations. I always used Motul V 300 10 W 50. But all depends of the way you drive and the temperature where are living. That´s important too.
It is important to know the capacity for the fluids in a car. For a 1999 Mercedes c230 Kompressor has an engine oil capacity of 6.1 quarts.
2005 Mercedes C230 Kompressor requires 6 quarts of oil.
c230 2004, how many quarts of oil is needed?
I use 5/30 synthetic oil for my 99 C230 Kompressor, and 03 C240
If it is the 202 motor, then 10-40 synthetic (Mobil brand is recommended)
To remove the oil cap on a C230 Mercedes Kompressor, first ensure the engine is off and cool for safety. Locate the oil cap, which is typically situated on top of the engine near the front. Grip the cap firmly and twist it counterclockwise to unscrew. If it's stuck, gently wiggle it while twisting to help loosen it.
