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

For the 2018 GMC Canyon equipped with the 2.8L 4-cylinder LWN 1 Diesel Turbo engine, the oil capacity is 6 quarts (including filter replacement). The recommended viscosity is 5W-30 for temperatures above -29\u00b0C and 0W-40 for temperatures below -29\u00b0C. AMSOIL recommends using AMSOIL 5W-30 100% Synthetic Diesel Oil<\/a> (DP530QT-EA<\/a>) paired with a WIX Oil Filter<\/a> for optimal protection.<\/p>\n

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

The 2018 GMC Canyon with the 2.8L LWN 1 diesel engine requires an oil grade of SEOA5. The specific viscosity depends on your operating environment: use 0W-40 for temperatures below -29\u00b0C and 5W-30 for temperatures above -29\u00b0C. Always check the oil level after refilling.<\/p>\n
