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

What oil does a 1982 Chevrolet Impala 5.7L Diesel take?<\/h2>\n

For the 1982 Chevrolet Impala with the 5.7L 8-cylinder Engine Code [N] Diesel, the recommended oil viscosity depends on ambient temperature: 10W-30 for temperatures below 16\u00b0C, 15W-40 for -18 to 16\u00b0C, and SAE 30 is preferred for temperatures above 0\u00b0C. The engine requires a capacity of 7 quarts with a filter change. AMSOIL recommends using their Signature Series or Heavy-Duty synthetic diesel oils for superior protection.<\/p>\n
