For the 2012 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 fall below 0\u00b0F (-18\u00b0C) to improve cold starting. AMSOIL recommends using Signature Series 15W-40 Max-Duty Diesel Oil<\/a> paired with an AMSOIL oil filter<\/a> for optimal protection.<\/p>\n
