AMSOIL diesel oil guide for trucks, vans, SUVs and diesel engines<\/figcaption><\/figure>\n

What oil does a 2010 Chevrolet Express 3500 6.6L LMM Diesel take?<\/h2>\n

The 2010 Chevrolet Express 3500 with the 6.6L 8-cylinder LMM 1 Diesel Turbo engine requires an oil capacity of 10 quarts<\/strong> (including filter replacement). The preferred viscosity is SAE 15W-40<\/strong> for temperatures above -18\u00b0C, though 5W-40<\/strong> is recommended for improved cold starting when ambient temperatures fall below 0\u00b0F (-18\u00b0C). AMSOIL recommends the Signature Series 15W-40 Max-Duty Diesel Oil<\/a> and the AMSOIL Oil Filter (EAO52-EA)<\/a>.<\/p>\n
