What oil does a 2001 Chevrolet Silverado 3500 6.6L Duramax take?<\/h2>\n

For the 2001 Chevrolet Silverado 3500 with the 6.6L LB7 Diesel Turbo engine, the recommended oil viscosity is SAE 15W-40 (preferred for temperatures above -18\u00b0C) or 10W-30. For colder climates below -18\u00b0C, 5W-40 is recommended to improve cold starting. The engine requires 10 quarts of oil with a filter change. AMSOIL recommends Signature Series 15W-40 100% Synthetic Max-Duty Diesel Oil<\/a>.<\/p>\n
