The recommended oil type and capacity for the 2003 Mercedes-Benz C-Class is 0W-40 and 5.8 quarts, respectively. Using high-quality oil is crucial for keeping the engine running smoothly. Problems can arise if the oil is not up to par. For instance, you might hear knocking sounds coming from the engine, or experience the engine stopping altogether due to poor-quality oil. Another common issue is a strong burning odor, which should be addressed promptly to prevent any serious complications, such as engine failure. Regular oil changes are essential, and a good rule of thumb is to do so every 5,000 to 10,000 miles. Neglecting to replace the oil can lead to engine issues down the line.
The 2003 Mercedes-Benz C230's standard 1.8L inline-4 engine uses 5.8 quarts of synthetic oil, while both versions of the 2.6L V6 engine in the 2003 Mercedes-Benz C240 require 7.9 quarts. The choice of oil viscosity is dependent on the weather conditions: temperatures below -4 F can use 0W30/5W30/0W40/5W40/5W50, while temperatures above -4 F require 10W30/10W40/10W50/10W60, and those above 5 F need 15W40/15W50, and above 23 F should use 20W40/20W50. Note: 2003 C230s with an oil cooler will require additional oil.
