What oil does a 1983 Chevrolet Malibu 4.3L Diesel take?<\/h2>\n

For the 1983 Chevrolet Malibu with the 4.3L 6-cylinder Engine Code [V] V Diesel, the engine requires an oil viscosity of 10W-30 for temperatures below 16\u00b0C, 15W-40 for temperatures between -18 to 16\u00b0C, or SAE 30 for temperatures above 0\u00b0C. The oil capacity is 7 quarts with a filter change. AMSOIL recommends using their Signature Series or Heavy-Duty synthetic diesel oils for superior protection.<\/p>\n
