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

For the 2006 Chevrolet Express 3500 equipped with the 6.6L 8-cylinder LLY Diesel Turbo engine, the oil capacity is 10 quarts with a filter change. SAE 15W-40 is the preferred viscosity for temperatures above -18\u00b0C, while 5W-40 is recommended for temperatures below -18\u00b0C to improve cold starting. AMSOIL recommends using Signature Series 15W-40 Max-Duty Diesel Oil<\/a> (DMEQT-EA<\/a>) paired with an AMSOIL Oil Filter<\/a> (EAO52-EA<\/a>) for optimal protection.<\/p>\n

What oil does a 2006 Chevrolet Express 3500 6.6L LLY take?<\/h2>\n

This vehicle requires an engine oil with a CH-4 specification. For most operating temperatures (above -18\u00b0C), SAE 15W-40 is the preferred viscosity. If you operate in extreme cold (below -18\u00b0C), using a 5W-40 viscosity can help improve cold starting performance.<\/p>\n
