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

For the 2022 GMC Sierra 2500 HD 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 when ambient conditions are below 0\u00b0F (-18\u00b0C) to improve cold starting. AMSOIL recommends using Signature Series 15W-40 Max-Duty Diesel Oil<\/a> and an AMSOIL oil filter<\/a> for optimal protection.<\/p>\n

What oil does a 2022 GMC Sierra 2500 HD L5P take?<\/h2>\n
