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

For the 2022 GMC Sierra 3500 Pickup with the 6.6L 8-cylinder L5P 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 to improve cold starting when ambient temperatures are below 0\u00b0F (-18\u00b0C). AMSOIL recommends using Signature Series 15W-40 Max-Duty Diesel Oil<\/a> (DMEQT-EA<\/a>) paired with an AMSOIL oil filter<\/a> for optimal protection.<\/p>\n

What oil does a 2022 GMC Sierra 3500 6.6L L5P take?<\/h2>\n

The 2022 GMC Sierra 3500 with the 6.6L L5P engine requires an oil grade of CJ-4. For standard operating temperatures above -18\u00b0C (0\u00b0F), SAE 15W-40 is preferred. However, if you are operating in environments where ambient temperatures drop below 0\u00b0F (-18\u00b0C), using a 5W-40 viscosity is recommended to improve cold starting performance.<\/p>\n

The total oil capacity for this engine is 10 quarts when performing a service that includes replacing the oil filter. It is essential to check the oil level after refilling to ensure accuracy. When performing the oil change, remember to replace the drain plug seal and torque the oil drain plug to 18 ft\/lbs.<\/p>\n
