For the 1984 Pontiac 6000 with the 4.3L 6-cylinder Engine Code [T] T Diesel, the oil capacity is 6 quarts (including filter replacement). Recommended viscosities include 10W-30 for temperatures below 16\u00b0C, 15W-40 for -18 to 16\u00b0C, and 30 viscosity for continuous driving above 0\u00b0C. AMSOIL recommends using Signature Series 10W-30 Max-Duty Diesel Oil<\/a> paired with an AMSOIL oil filter<\/a> for optimal protection.<\/p>\n

What oil does a 1984 Pontiac 6000 4.3L Diesel take?<\/h2>\n
