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

What oil does a 2018 Chevrolet Colorado 2.8L Diesel take?<\/h2>\n

The 2018 Chevrolet Colorado with the 2.8L 4-cylinder (Engine Code LWN 1) diesel engine requires an oil capacity of 6 quarts when changing with a filter. The recommended viscosity is 5W-30 for temperatures above -29\u00b0C, or 0W-40 for temperatures below -29\u00b0C. AMSOIL recommends AMSOIL 5W-30 100% Synthetic Diesel Oil<\/a> (DP530QT-EA<\/a>) for this application.<\/p>\n
