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

For the 2018 Chevrolet Equinox with the 1.6L 4-cylinder Diesel Turbo engine (Engine Code [U] LH7 U), the oil capacity is 5.3 quarts with a filter change. The recommended viscosity for all temperatures is 5W-30, though 0W-40 is suggested for temperatures below -29\u00b0C. AMSOIL recommends using AMSOIL 5W-30 100% Synthetic Diesel Oil<\/a> (DP530QT-EA<\/a>) paired with an AMSOIL Oil Filter<\/a> (EA15K35-EA<\/a>) for optimal protection.<\/p>\n
