What oil does a 1985 Pontiac Parisienne 5.7L Diesel take?<\/h2>\n

For the 1985 Pontiac Parisienne 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 30 weight is preferred for continuous driving above 0\u00b0C. The engine requires a capacity of 7 quarts with a filter change. AMSOIL recommends using Signature Series or Heavy-Duty synthetic diesel oils for superior protection.<\/p>\n
