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°C is SAE 15W-40, though 5W-40 is recommended for all temperatures when ambient conditions are below 0°F (-18°C) to improve cold starting. AMSOIL recommends using Signature Series 15W-40 100% Synthetic Max-Duty Diesel Oil (DMEQT-EA) paired with an AMSOIL Oil Filter (EAO52-EA).
What oil does a 2016 GMC Savana 2500 6.6L take?
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°C. If you are operating in environments where ambient temperatures drop below 0°F (-18°C), use a 5W-40 viscosity to improve cold starting capabilities.
