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

For the 2016 GMC Savana 2500 with the 6.6L 8-cylinder LGH 7 Diesel Turbo engine, the oil capacity is 10 quarts (with filter). The preferred viscosity for temperatures above -18\u00b0C is SAE 15W-40, though 5W-40 is recommended for all temperatures when ambient conditions are below 0\u00b0F (-18\u00b0C) to improve cold starting. AMSOIL recommends using Signature Series 15W-40 100% Synthetic Max-Duty Diesel Oil<\/a> (DMEQT-EA<\/a>) paired with an AMSOIL Oil Filter<\/a> (EAO52-EA<\/a>).<\/p>\n

What oil does a 2016 GMC Savana 2500 6.6L take?<\/h2>\n

The 2016 GMC Savana 2500 with the LGH 7 diesel engine requires an oil grade of CJ-4. For optimal performance, SAE 15W-40 is preferred for temperatures above -18\u00b0C. If you are operating in environments where ambient temperatures drop below 0\u00b0F (-18\u00b0C), use a 5W-40 viscosity to improve cold starting capabilities.<\/p>\n

AMSOIL product recommendations<\/h2>\n
