Use ONLY engine oils that have one of these designations: CI-4 or CH-4 for DURAMAX diesel engines.
Use SAE 10W-30 if temperatures stay above 0Deg.F (-18Deg.C) before your next oil change. When it is very cold, Below 0Deg.F (-18Deg.C), you should use SAE 5W-30 to improve cold starting and prevent engine damage. DO NOT use other viscosity oils such as SAE 10W-40 or SAE 20W-50. |
