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

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

The 1982 Cadillac Seville with the 5.7L 8-cylinder Engine Code [N] requires an oil viscosity of 10W-30 for temperatures below 16\u00b0C, 15W-40 for temperatures between -18 to 16\u00b0C, or 30 for temperatures above 0\u00b0C (preferred for continuous driving). The engine oil capacity is 7 quarts with a filter change. AMSOIL recommends using their Signature Series or Heavy-Duty synthetic diesel oils for optimal protection.<\/p>\n
