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

For the 1982 Cadillac Eldorado with the 5.7L 8-cylinder Engine Code [N] Diesel, the required oil viscosity depends on ambient temperatures: 10W-30 is used below 16\u00b0C, 15W-40 between -18 to 16\u00b0C, and 30 is preferred for continuous driving above 0\u00b0C. The engine oil capacity is 7 quarts with a filter change. AMSOIL recommends using Signature Series or Heavy-Duty synthetic diesel oils for optimal protection.<\/p>\n
