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

For the 2014 GMC Savana 2500 equipped with the 6.6L 8-cylinder LGH M Diesel Turbo engine, the oil capacity is 10 quarts<\/strong> (including filter replacement). The preferred viscosity for temperatures above -18\u00b0C is SAE 15W-40<\/strong>, though 5W-40<\/strong> is recommended for all temperatures when ambient conditions are below 0\u00b0F (-18\u00b0C) to improve cold starting. AMSOIL recommends Signature Series 15W-40 Max-Duty Diesel Oil<\/a> and the EAO52-EA oil filter<\/a>.<\/p>\n

What oil does a 2014 GMC Savana 2500 6.6L Diesel take?<\/h2>\n

The engine requires an oil with a CJ-4 specification. For standard operating temperatures above -18\u00b0C (0\u00b0F), SAE 15W-40 is the preferred viscosity. If you are operating in extreme cold where ambient temperatures drop below 0\u00b0F (-18\u00b0C), AMSOIL recommends using 5W-40 to improve engine cold starting performance.<\/p>\n
