How often do you change oil in Mercedes Benz C300?

Mercedes-Benz recommends changing the oil in the C300 every 10,000 miles or once a year, whichever comes first. However, you may need to change the oil more frequently if you drive in severe conditions, such as dusty or muddy roads, or if you tow a trailer.

Here are some signs that your C300's oil needs to be changed:

* The oil level is low.

* The oil is dark and dirty.

* The oil smells burnt.

* The engine is knocking or making other unusual noises.

If you notice any of these signs, take your C300 to a qualified mechanic to have the oil changed.
