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

p<\/p>\n

For the 2021 GMC Savana 2500 equipped with the 2.8L 4-cylinder Diesel Turbo engine (Engine Code [1] LWN 1), the recommended oil viscosity is 5W-30 for all temperatures, or 0W-40 for temperatures below -29\u00b0C. The engine oil capacity is 5.9 quarts when performing a change with a filter. AMSOIL recommends AMSOIL 5W-30 100% Synthetic Diesel Oil<\/a> (DP530QT-EA<\/a>) for outstanding protection in this diesel application.<\/p>\n

What oil does a 2021 GMC Savana 2500 2.8L Diesel take?<\/h2>\n

The 2021 GMC Savana 2500 with the 2.8L 4-cylinder diesel engine requires an oil viscosity of 5W-30 for all temperature ranges. If you are operating in extreme cold (below -29\u00b0C), a 0W-40 viscosity is recommended. The AMSOIL lookup note mentions that vehicles originally using GM Dexos2 may use a GM Dexos D licensed engine oil of the appropriate viscosity grade.<\/p>\n
